Accessing the Archive with the MailStore Client software

Installation & Update

The MailStore Client setup file that matches your MailStore Server version is stored on the MailStore Server machine. Follow the Install MailStore Client on other Computers link on your desktop and copy the corresponding setup file to the client computer.

It is a regular Windows setup program, that can by executed on the appropriate client computer by double-clicking on the setup file. Just follow on-screen instructions.

Notice: Alternatively to installing the MailStore Client application manually, you can also deploy it to the client computer though the Active Directories Group Policy feature. More information on that can be found in the article MailStore Client Deployment

If an update is installed on the MailStore Server computer, MailStore Client updates itself automatically on first login to stay compatible with MailStore Server. Therefore a re-installation of MailStore Client is usually not required.

Starting and Login

Start MailStore Client by using the appropriate link on the desktop.

The window Connect to MailStore Server appears.

Enter the DNS host name of the computer on which MailStore Server is installed into Server Name. Be aware, that the pre-filled entry localhost only works if the MailStore Client is run from the same machine where MailStore Server is installed.
Click Connect to connect to MailStore Server.

Hint: Did you activate the option Always connect to this server and you want to change the destination server later? Hold the Shift key pressed while opening MailStore Client.

After establishing the connection to MailStore Server, MailStore Client checks if newer a version of its own program files is available for downloading and, if necessary, updates these automatically.

Once the connection was established successfully, the user name dialog appears.

Enter the user name of a MailStore user into the User Name field and click on Next.

MailStore Server now determines how the user is to be authenticated.

If MailStore Server is able to verify the user's credentials itself, the password dialog as shown on the right appears. Enter the password into the Password field and click on Log in.
If the user authenticates against Microsoft 365, Google Workspace or Active Directory Federation Services (AD FS), the default web browser will be opened to allow authentication through Microsoft's, Google's or the AD FS's authentication service.

If Multi-factor Authentication has been enabled , and the current device is not trusted, the user has to enter an MFA code.

The MailStore Folder Structure

For each user, MailStore creates a folder on the highest level of the folder structure which corresponds to the archive of the respective user. It contains all emails that were archived for this user and is labeled My Archive.

If the user has access to the archives of other MailStore users (as MailStore administrator, for example), their folders are listed as Archive of <User Name> under the top level folder Other Archives

Below these main folders, the individual email sources (e.g. Microsoft Outlook or Exchange mailboxes) and their folder structures (e.g. Inbox) are listed.

Notice: For MailStore administrators, accessing the archives of other users via the folder structure is blocked by default; this setting can be changed in the compliance settings. Additionally, MailStore administrators can manage archives via the Archives page.

Deleting Folders

Folders and the emails contained therein can only be deleted after the appropriate user privileges have been assigned explicitly by the administrator. If the folder to be deleted contains any subfolders, they will be deleted as well.

Moving, Renaming, and Creating Folders Manually

Within MailStore, folders can be moved, renamed or created. Regular users can only do this within their own user archive, while MailStore administrators can move and rename folders beyond the boundaries of user archives.During the archiving process, MailStore adopts the folder structure and the folder names of the source (e.g. Microsoft Outlook).

Please note that moving large archives across the borders of user archives can take some time because the emails being moved have to be gathered by the full text index of the target user.

The features New Folder..., Rename and Move to Folder... can be accessed by right-clicking on the corresponding archive folder.

If a MailStore administrator renames a user archive (Folder: Archive of <user name>) without renaming the corresponding user, an empty archive will exist with this user name until it is changed.

Hint: Using an already existing folder name when renaming a folder, allows to merge the content of both folders.

Changing Message Type

In case the message recipient is shown wrongly instead of the message sender or vice versa, an administrator is able to change the message type of a message.

Highlight the emails and select Change Message Type in the context menu.

In case the message type of other users' message should be changed, archive access has to be unblocked.

Verify the archiving profile settings if necessary, so that the message type is already set correctly during archiving.

Deleting Emails

Highlight the emails to be deleted by clicking on the emails while holding down the Ctrl key (Ctrl+A will highlight all emails). Right-click on the highlighted item(s) and select Delete. Users are only allowed to delete emails if they have received this privilege explicitly from the MailStore administrator.

Please keep in mind that allowing users to delete emails is not recommended; assigning such privileges makes it difficult, if not impossible, to comply with legal requirements regarding the storage of emails.

Moving Emails

Highlight the emails to be moved by clicking on the emails while holding down the Ctrl key (Ctrl+A will highlight all emails). Right-click on the highlighted item(s), select Move To Folder... and select a destination folder. Alternatively, drag and drop the highlighted emails into the destination folder. Emails can only be moved within a user archive unless you are a MailStore administrator.

Searching by Folder Structure

MailStore sorts all archived email into MailStore's own folder structure. Below the main folders, the individual email sources (e.g. Microsoft Outlook or Exchange mailboxes) and their folder structures (e.g. Inbox) are listed.

Viewing the Emails in a Folder

To view the emails in a folder, simply click on the folder name. The emails will be listed below the folder structure.

Click on the text Sorted by: <value> to change the order in which emails are displayed. Emails can be sorted according to:

Date
From/To (sender/recipient of the email)
Subject

Click on the Field to the right of Sorted by ("New to Old" in the screenshot) to reverse the order in which emails are arranged. By default, the latest email is displayed first.

Refreshing the View

To refresh the list of folders, click on a folder and press F5 on your keyboard.

Click on the folder again to refresh the list of emails.

Starting an Advanced Search in a Folder

To start an advanced search in a folder, right click on the folder and select Search here.... The advanced search is shown and the folder is preselected.

Quick Search

With quick search you can browse all emails located in the archives you have access to. This feature is especially suitable for simple queries; alternatively, the advanced search can be used.

Using Quick Search

The input field is located in the upper left part of the MailStore Client. Simply enter one or more keywords and press ENTER. The search results are displayed. Keywords which appear in the header or the subject line are highlighted.

Searching for Word Fragments

To display all emails containing a word with a particular fragment, use the wildcard character (*). For example:

auto*

will return emails with auto, automatic, automobile etc.

*example.com

will return emails with all email addresses and domains of example.com.

firstname.lastname*

will return emails with all email addresses of firstname.lastname.

Searching for Words with unknown letters

To view all emails containing a word where you do not know how to spell it correctly, you can use the question mark (?). For example

Me?er

would find emails with Meier and Meyer, but not Maier.

The question mark (?) cannot be used at the beginning of a word or at the end of a word, use the wildcard character (*) instead.

Searching for Phrases

To search for words appearing consecutively and in a specific order, use quotation marks (""). For example:

"Microsoft Windows"

will return the text Microsoft Windows but not Microsoft Works or Windows 95.

Phrases cannot contain the wildcard characters (?) and (*).

Narrowing by Fields

A search for keywords or phrases can be limited to specific fields. For example:

subject:News                  only in Subject
from:[email protected]         only in From
to:[email protected]        only in To
cc:[email protected]           only in Cc
bcc:[email protected]     only in Bcc
bcontent:billing              only in Body of message
acontent:billing              only in Attachments of message

Searching for Alternatives

Use square brackets [] to search for alternative words. Example:

[Support Request Form]

finds emails that contain the word support or the word request or the word form or any combination of these.

[from:[email protected] subject:important "very important"]

finds emails that come from [email protected] or have the word important in the subject or contain the phrase very important anywhere in the email.

Excluding Words

To narrow a search, you may want to specify words which must not be present in the emails. To exclude words from the search results, prepend the word with the minus character (-). For example:

ZDNet -download-tip

returns all emails from ZDNet which do not contain download-tip.

ZDNet -download-tip -"free gift"

returns all emails from ZDNet which do not contain download-tip and do not contain the phrase free gift.

Exclusions cannot be used in alternatives, so

[Microsoft Windows -Powerpoint]

is not valid, but

[Microsoft Windows] -Powerpoint

is valid and will find emails that contain Microsoft or Windows but not the word Powerpoint.

Valid is also

-[Microsoft Windows Powerpoint]

which returns all emails that do not contain any of the words Microsoft, Windows or Powerpoint.

Combining Search Options

Any of the search options described above can be combined. For example:

ZDNET -"Daily Update"

returns all emails from ZDNet which do not contain the consecutive words Daily Update.

from:ZDNET bcontent:ACME

returns all emails from ZDNET which have ACME somewhere in their message body.

from:[email protected] acontent:bill

returns all emails from [email protected] which have bill in any attachment.

to:[email protected] -sales

returns all emails to [email protected] which do not have sales in any part of the email.

[from:[email protected] from:[email protected]] acontent:Invoice -subject:Reminder

finds all emails from [email protected] or [email protected] that have Invoice in an attachment but no Reminder in the subject.

[from:[email protected] from:[email protected]] [bill admonition] -[to:[email protected] cc:[email protected] bcc:[email protected]]

returns all emails from [email protected] or [email protected] that do have bill or admonition anywhere and are not sent to [email protected].

from:[email protected] to:[email protected] acontent:bill -subject:admonition

returns all message from [email protected] to [email protected] which have bill in any attachment but do not have admonition in the subject.

About Special Characters

Words inside indexed emails or attachments which are a combination of alphanumeric (letters, digits) and non-alphanumeric characters (white space, line break, delimiter or other control characters), may be returned in search results when searching for the alphanumerical part only.

For instance, when searching for firstname, firstname.lastname and lastname, e-mails containing the word firstname.lastname will be returned.

Separators and control characters that cause this behavior:

Period (.)
Comma (,)
Semicolon (;)
Hyphen (-)
Underscore (_)
AT-Sign (@)
Slash & Backslash (/,\)
Null character (NUL)

When the original text was divided by a different character, e.g. firstname(lastname, then only the full term is present in the index and one has to know the full term or has to use the wildcard character (*) to find emails containing that text.

Special characters at the beginning and the end of text are stripped and not present in the search index. It cannot be searched for these characters.

Advanced Search

Using the advanced search, you can execute complex queries through the MailStore Client. Queries can be scoped to certain archive folders and may not only refer to the email content but also include fields such as email date, archiving date or email size.
