Note that while Office 365 manages users in Azure Active Directory, this itself can be synchronized with on-premise user information. Even if Office 365 / Azure AD is not the primary source of user account information in your environment, it is highly recommended to synchronize MailStore directly with Office 365 to fetch all information that is relevant for archiving such as email addresses.

This implementation guide covers the specifics of archiving Exchange Online / Office 365 mailboxes. It is assumed that you already have a MailStore Server installation or test installation and are familiar with the fundamentals of MailStore Server. Please refer to the Manual or the Quick Start Guide for more information.

MailStore Server offers several ways to archive emails from Exchange Online / Office 365 mailboxes, which are described below. If you are not sure which archiving method best suits your company, please refer to the chapter Choosing the Right Archiving Strategy.

Please note: For better readability the term Exchange Online / Office 365 hereinafter is being referred to as Office 365.

Synchronizing Users

MailStore offers direct user synchronization support for Office 365. The setup procedure for the required service principal is described in the chapter Office 365 Integration of the MailStore Server manual.

Note that while Office 365 manages users in Azure Active Directory, this itself can be synchronized with on-premise user information. Even if Office 365 / Azure AD is not the primary source of user account information in your environment, it is highly recommended to synchronize MailStore directly with Office 365 to fetch all information that is relevant for archiving such as email addresses.

Archiving Individual Office 365 Mailboxes

In MailStore Server Office 365 archiving tasks are stored in archiving profiles. By following the procedure described here you can archive a single Office 365 mailbox for a specific MailStore user. The archiving process can be executed manually or automatically. You can find further information about executing archiving profiles in chapter Email Archiving with MailStore Basics.

Important notice: Archiving a single mailbox requires the Exchange Online feature EWS Application support. Please make sure that your Office 365 plan supports this feature. More information is available in this TechNet article.

For each mailbox, please proceed as follows:

  • Unless the mailbox of the current user is to be archived into his or her own user archive, log on to MailStore Client as MailStore administrator. Only an administrator can archive emails for other users.
  • Click on Archive Email.
  • From the Email Servers list in the Create Profile area of the window, select Microsoft Exchange to create a new archiving profile.
  • A wizard opens to assist in specifying the archiving settings.
  • Select Single Mailbox.
    Office365 mailbox 01.png
  • Leave the protocol under Access via on HTTPS. Also the option Ignore SSL Warnings should be left deactivated because Office 365 uses official certificates.
  • Leave the setting of Host to its default (Auto Detect).
  • Under User Name, enter the Office 365 login name of the user whose emails are to be archived (e.g. barbara.ross@example.com).
    Please note: Alternatively, any user with the appropriate access permissions for the mailbox to be archived can be specified. In this case, it is imperative that this mailbox is specified under Mailbox (see below).
  • Under Password, enter the user's password.
  • The field Mailbox must be left blank if a user, whose Office 365 login name and password is being used, wants to archive his own mailbox. Otherwise, the primary email address of the user whose mailbox you want to archive has to be entered here.
  • Click on Test to verify that MailStore can access the mailbox.
  • Click on Next.
  • If needed, adjust the settings for the List of Folders to be Archived, the filter and the Deletion Rules. By default, no emails will be deleted from the mailbox. The Timeout value only has to be adjusted in specific cases (e.g. with very slow servers).
    Xchg mailbox 03.png

    Important notice: Did you specify IMAP as the protocol and have also defined a deletion rule? If so, folders containing no emails, such as Tasks, Calendar or Contacts have to be added to the list of excluded folders manually. This is the only way to avoid these folders being archived and deleted according to the deletion rule specified. Please read more in chapter Archiving Specific Folders.

  • Click on Next to continue.
  • If logged on to MailStore Server as MailStore administrator, the Target Archive can be specified. Select the archive of the user for whom the selected mailbox is to be archived. If the user does not exist yet, click on Create a New User.
    Xchg mailbox 02.png
  • Click on Next.
  • In the last step, a name for the archiving profile can be specified. After clicking Finish, the archiving profile will be listed under Saved Profiles and, if desired, can be run immediately or automatically.


Archiving Multiple Office 365 Mailboxes Centrally

With MailStore, some or all Office 365 mailboxes can be archived in a single step. All necessary preparations, such as creating MailStore users, and also the archiving process itself can be executed manually or automatically.
Before the archiving process can be set up in MailStore, a service account needs to be created that has access to all mailboxes.

Important notice: Archiving multiple mailboxes requires the Exchange Online features EWS Application support and Role-Based Permissions. Please make sure that your Office 365 plan supports these features. More information is available in this TechNet article.

Step 1: Setting up a service account for accessing mailboxes

To be able to archive multiple Office 365 mailboxes, you need to create an Office 365 user first. Afterwards follow these steps, to grant access permissions to the newly created user on all mailboxes:

  • Log on to your Office 365 tenant through Microsoft's Online Portal with an admin account.
  • In the Office 365 admin center choose ADMIN > Exchange.
  • Now, in the Exchange admin center, navigate to permissions.
  • Under admin roles select + (New).
    Arch office365 multi 01.png
  • Enter a meaningful name (e.g. MailStore Impersonation) and description for the new role group.
  • Under Roles add the role ApplicationImpersonation.
  • Under Members add the user you want to give permission to access all mailboxes.
  • Click on Save to create the new role group.

Step 2: Configuration of MailStore Server

Please proceed as follows:

  • Log on to MailStore Client as MailStore administrator.
  • Click on Archive Email.
  • From the Email Servers list in the Create Profile area of the window, select Microsoft Exchange to create a new archiving profile.
  • A wizard opens to assist in specifying the archiving settings.
  • Select Multiple Mailboxes.
    Please note: In order to be able to archive multiple mailboxes, the MailStore users along with their email addresses have to exist in the MailStore user management. If this is not the case, MailStore will offer to set up and execute the directory synchronization at this point. Once completed, the wizard will resume.
    Alternatively, you can cancel the wizard and create users manually as described the in chapter User Management.
    Office365 mailboxes 01.png
  • Leave the protocol under Access via on HTTPS. Also the option Ignore SSL Warnings should be left deactivated because Office 365 uses official certificates.
  • Leave the setting of Host to its default (Auto Detect).
  • Under User Name and Password, enter the access data of the service account that has access to all mailboxes to be archived.
  • Click on Next to continue.
    Xchg mailboxes 03.png
  • If needed, adjust the settings for the List of Folders to be Archived, the filter and the Deletion Rules. By default, no emails will be deleted from the mailbox. The Timeout value only has to be adjusted in specific cases (e.g. with very slow servers). Please keep in mind that these settings apply to all mailboxes to be archived, as specified in the next step.
  • Select the users whose mailboxes are to be archived.
    Xchg mailboxes 02.png
    The following options are available:
    • All users with configured email address
      Choose this option to archive the mailboxes of all users who are set up, along with their email addresses, in MailStore's user management.
    • All users except the following
      Choose this option to exclude individual users (and thereby their Office 365 mailboxes) from the archiving process, using the list of users below.
    • Only the following users
      Choose this option to include individual users (and thereby their Office 365 mailboxes) in the archiving process, using the list of users below. Only the mailboxes of those users explicitly specified will be archived.
    • Synchronize with Directory Services before archiving
      If selected, the MailStore user list will be synchronized with the configured directory service before any archiving process is executed. This has the advantage that, for example, new employees will be created as MailStore users before archiving, so once the archiving process is executed, their Office 365 mailbox is archived automatically as well. This option is especially recommended when the archiving process is to be executed automatically.
  • Click on Next.
  • In the last step, a name for the archiving profile can be specified. After clicking Finish, the archiving profile will be listed under Saved Profiles and can be run immediately or automatically, if desired.


Archiving Incoming and Outgoing Emails Directly

Together with the Office 365 journal function, MailStore can archive the incoming and outgoing emails of all users automatically. This is the only way to ensure that all emails are archived entirely.

Basic Functionality

The Office 365 journal function makes it possible to record all incoming, outgoing and internal email traffic. At the time of sending and receiving, a copy of the respective email is created by Office 365. The copy is then attached to a so-called journal report and stored in a special journal mailbox. The journal report contains information about the actual senders and recipients; Office 365 also resolves BCC recipients and distribution lists.

With the corresponding archiving profile MailStore can archive the journal mailbox automatically. During this process, MailStore parses the information in the journal reports and assigns the emails to their respective MailStore archives. Therefore even with journal archiving all users have access to their own emails only.

Important Notes: Exchange Online as part of Office 365 currently supports only external, non-Office 365 mailboxes as journal mailbox. The free MailStore Gateway program provides mailboxes that are suitable as target for Exchange Online journal rules. More information about journaling in Exchange Online can be found in this TechNet article.


Step 1: Setup and Configure MailStore Gateway

Please refer to the MailStore Gateway Manual for detailed instructions about:

  • Installation and Setup of MailStore Gateway
  • Logging on to MailStore Gateway's Management Console
  • Creating MailStore Gateway mailboxes

After these steps, a mailbox with an individual email address (e.g. mbx-dead1234beef5678@gateway.example.com) should exist.

Step 2: Creating a Journal Rule

The following steps describe how to set up journaling for your Microsoft Office 365 account.

  • Log on to your Office 365 tenant through Microsoft's Online Portal with an admin account.
  • In the Office 365 admin center choose ADMIN > Exchange.
  • Now, in the Exchange admin center, navigate to compliance management.
  • Select journal rules.
  • Under Send undeliverable journal reports to select an alternate journaling mailbox that receives None Delivery Reports (NDRs) for undeliverable journal reports in case the primary journal mailbox is unreachable. This mailbox must be a dedicated mailbox, any mail sent to this mailbox won't be delivered and not journaled.
  • Click on + (New).
    The dialog window New Journal Rule opens:
    Arch office365 journal 01.png
  • Enter a name for the journal rule, e.g. Journaling.
  • In the If the message is sent to or received from... section select whether the rule should apply to all messages or to specific users or groups.
  • Under Journal the following messages..., choose whether to capture all messages, internally sent messages only, or only those messages with an external sender or recipient.
  • Enter the email address of the previously created MailStore Gateway mailbox in the Send journal reports to: box.
  • Click on save to activate the rule.

Step 3: Configuration of MailStore

Setting up archiving processes for MailStore Gateway mailboxes is done using archiving profiles. General information about archiving profiles is available in chapter Working with Archiving Profiles.

Before configuring MailStore Server, please make sure that a MailStore user account exists for each user whose emails are to be archived with the MailStore Gateway. Please refer to chapter User Management for more information.

Important notice: It is imperative that, in user management under Properties, the email address is specified for each user. This is the only way to make sure that the emails in the archive are assigned to the appropriate users.

Please proceed as follows:

  • Log on as MailStore administrator using MailStore Client.
  • In MailStore, click on Archive Email.
  • To create a new archiving profile, select MailStore Gateway Mailbox from the Email Server list in the Create Profile area of the application window.
  • A wizard opens that guides you through the setup process.
    Arch MailStore Gateway Office365 01.png
  • Select Microsoft Exchange Online / Office 365 and click OK.
  • Fill out the fields Host, Mailbox ID and Password. Click on Test to verify the data entered.

    If MailStore Gateway uses a TLS certificate from a certificate authority that is not trusted by the MailStore Server computer, the option Ignore SSL warnings might need to be checked.

    Arch MailStore Gateway Office365 02.png
  • Adjust any further settings such as how to handle emails with unknown addresses or asking MailStore to delete emails after they have been archived.
  • If the option Synchronize with Directory Services before archiving is enabled, the MailStore user list will be synchronized with configured directory service before the archiving process actually runs. This has the advantage that, for example, new employees will be created as MailStore users before archiving which enables MailStore to sort their emails into the correct archives.
  • Click on Next.
  • The timeout value only has to be adjusted on a case-by-case basis (e.g. with very slow servers).
  • Click on Next.
  • At the last step, select a name for the new archiving profile. After clicking on Finish, the archiving profile will be listed under Saved Profiles and can be run immediately or automatically, if desired.


Public Folders

MailStore Server can archive the emails from the public folders of Office 365 and make them available to some or all MailStore users. The archiving process can be executed manually or automatically.

Please note: Archiving public folders requires the Exchange Online features EWS Application support and Public Folders. Please make sure that your Office 365 plan includes these features. You can find more information in this Technet article.

Step 1: Creating a User Archive for Public Folders

Archived emails are always assigned to a particular user. You also need to specify a target archive when archiving a public folder.

As best practice, please create a dedicated MailStore user (e.g. publicfolder) whose archive acts as target for the public folder archiving profile. Through the MailStore privileges you can grant access to the archive of the user publicfolder to other MailStore users. This way the archived emails of the public folder are made available to those MailStore users.

You can find more information on how to create a new user in MailStore in the chapter User Management.

Step 2: Granting permissions on public folders in Office 365

Accessing public folders needs an Office 365 user that has a mailbox because the necessary permissions are implemented on mailbox level. If the above mentioned MailStore service account should be used for public folder access also, an Office 365 license has to be assigned to that account first.

To grant the Office 365 user the necessary permissions, please proceed as follows:

  • Log on to your Office 365 tenant through Microsoft's Online Portal with an admin account.
  • In the Office 365 admin center choose ADMIN > Exchange.
  • Now, in the Exchange admin center, navigate to public folders.
  • Click on the Ellipsis (…) and select Root permissions.
    Arch office365 pf 01.png
  • A new browser window opens. Click on + (Add).
  • Use Browse to choose the Office 365 user you want to grant permissions.
  • Choose Custom as Permission level and grant Read items and Delete all permissions.
    Arch office365 pf 02.png
  • Click on Save.
  • Enable the option Apply changes to this public folder and all its subfolders.
  • Click on Save.
  • Click on Close after saving has been completed successfully.

Step 3: Setting up the Archiving Process

Please proceed as follows:

  • Log on to MailStore Client as administrator.
  • Click on Archive Email.
  • From the Email Servers list in the Create Profile area of the window, select Microsoft Exchange to create a new archiving profile.
  • A wizard opens to assist in specifying the archiving settings.
  • Select Public Folders.
    Office365 public 01.png
  • Under Access via, leave the protocol on HTTPS. The option Ignore SSL Warnings should also be left deactivated because Office 365 uses trusted certificates.
  • Leave the setting of Host to its default (Auto Detect).
  • Under User Name, enter the Office 365 login name of the user you have prepared in step 2 for public folder access.
  • Under Password, enter the user's password.
  • Leave the field Mailbox to its preset value /public.
  • Click on Test to verify that MailStore can access the public folders.
  • Click on Next to continue.
    Xchg public 03.png
  • Adjust the settings for the List of Folders to be Archived. By default, all public folders that contain emails will be archived.
  • If needed, adjust the filter and the Deletion Rules. By default, no emails will be deleted from the public folders. The Timeout value only has to be adjusted in specific cases (e.g. with very slow servers).
  • Click on Next to continue.
    Xchg public 02.png
  • In the next step, select the archive of the user you have prepared in step 1.
  • In the last step, specify a name for the archiving profile. After clicking Finish the archiving profile will be listed under Saved Profiles and can be run immediately or automatically if desired.


Shared Mailboxes

Shared mailboxes grant multiple users shared access to a mailbox, somewhat comparable to public folders.

Step 1: Creating a MailStore User for a Shared Mailbox

A shared mailbox is a special kind of mailbox that, unlike a normal mailbox, is associated with an Azure AD account that has no Microsoft Exchange Online license assigned to it. Like for normal mailboxes, MailStore is able to create user entries for shared mailboxes via Azure AD synchronization. For this, you have to deactivate the option Synchronize licensed Microsoft Exchange Online users only in the section User Database Synchronization.
After synchronization you can grant MailStore users access to the archive of the shared mailbox by assigning privileges.

Step 2: Setting up the Archiving Process

Further steps are analog to the archiving of individual or multiple Office 365 mailboxes.
