Upgrading to 24.2.1

If you are upgrading from a MailStore version before 24.2.0, please also note the instructions for upgrading to version 24.2.0.

• Upgrading Archive Stores
  If you upgrade from MailStore 24.2.0, the archive stores need to be upgraded. To do this, proceed as follows:
  • Log in to the Management Console.
  • Click on Instances
  • Select the instance to upgrade
  • Open the Storage tab

  The master database is upgraded to Firebird 4 during the first start of an instance. This process might extend the time required for the first start of the instance by several minutes.
• Upgrading Archive Stores
  For the update to Firebird 4 the databases of the archive stores must be upgraded. Proceed as follows to upgrade:
  • Log in to the Management Console.
  • Click on Instances
  • Select the instance to upgrade
  • Open the Storage tab
  • Click the Upgrade All Stores button to upgrade all archive stores of that instance.
  • Click on OK to start the upgrade process or click on Cancel.

Until all archive stores have been upgraded, retention policies are not available.

• Python API Wrapper

  In order to be able to use the new API commands, an update of the Python API wrapper library is required.

Known Issues

• As long as an internal, Firebird-based archive store has not been updated, no recovery records will be written for emails in this archive store. This bug was fixed with version 24.2.1.

Upgrading to 23.4.0

• System Requirements
  Windows Server 2012 and Windows Server 2012 R2 support has been removed from MailStore in this version. For a current list of supported operating systems, please refer to System Requirements.
• Python API Wrapper

  In order to be able to use the new API commands, an update of the Python API wrapper library is required.

Upgrading to 23.3.0

• Microsoft Exchange 2013 Support

  Support for Microsoft Exchange 2013 has been removed from MailStore in this version.

Upgrading to 23.2.0

• Outlook Add-in

  Starting with version 23.2.0, MailStore SPE instances support multi-factor authentication for users with integrated authentication. To support multi-factor authentication an update of the Outlook Add-in is required.

  The Outlook Add-In 23.2.0 is not backward compatible with older MailStore SPE versions. When updating, MailStore SPE should be updated first and then the Outlook Add-in.

• Scheduled Tasks, Management API, IMAP Access
  

  When multi-factor authentication is enabled for a user and that user wants to schedule client-side archiving profiles, access the Management API or access the IMAP server, an app password has to be used instead of the regular password.

• Python API Wrapper

  In order to be able to use the new API commands, an update of the Python API wrapper library is required.

Known Issues

• When using the E-mail Archive client to connect to an SPE instance, the given username must not contain any upper case letters otherwise an error message will appear. This issue has been resolved in version 23.3.0.

Upgrading to 23.1.0

• System Requirements
  Windows Server 2008 R2 support has been removed from MailStore in this version. For a current list of supported operating systems, please refer to System Requirements.

Upgrading to 22.4.0

• Management API
  Administrators have to use an API password to use the Management API when MFA is enabled for them. That API password can be generated in the Management Console.

Upgrading to 22.3.0

• Outlook Add-in

  Starting with version 22.3.0, failed login attempts will slow down the login process. While this process is backwards compatible to older Outlook Add-ins, we strongly recommend updating the Outlook Add-in for the best user experience.

Upgrading to 22.2.x

• System Requirements

  Starting with version 22.2 MailStore Service Provider Edition and its components require Microsoft .NET Framework version 4.8. Please refer to our System Requirements.
  

  If the framework is installed by the MailStore setup, the system might reboot without further notice.

Upgrading to 13.x

• Update of MailStore Client and Outlook Add-in
  Irrespective of MailStore Client's auto-update mechanism, a reinstallation of MailStore Client and the MailStore Outlook Add-in is required to make use of the following improvements:
  • Unified validation of TLS certificates.
  • Unified evaluation of group policies.
  • Distinct error messages for certain certificate errors.
  • Outlook Add-in: Due to the required changes of the login process to support modern authentication with Microsoft 365 and Google Workspace, the Outlook Add-in must be updated to version 13 to be able to connect to MailStore SPE 13.x. Connecting to an older version of MailStore SPE is no longer supported after the update.
• Microsoft 365 Support

  A new directory service synchronization profile Microsoft 365 (Modern Authentication) as well as new profiles for archiving and exporting emails from or to Microsoft 365 have been introduced. These support modern authentication (OAuth 2.0 & OpenID Connect) and customers of Microsoft 365 are advised to regularly check for Microsoft's announcement on the timeline for removing HTTP Basic Auth from Microsoft Exchange Web Services (EWS) and to plan the migration to the new profiles in advance.
  

  Once Microsoft disables support for HTTP Basic Auth in Exchange Web Services on Microsoft 365, the existing directory service synchronization profile Microsoft 365 (Basic Auth) (formerly named Office 365) and the Microsoft Exchange archiving and export profiles will stop working.

• Google Workspace Support

  The Google Workspace directory service synchronization profile has been extended with support for modern authentication (OAuth 2.0 & OpenID Connect). Customers of Google Workspace are advised to regularly check for Google's announcement on the timeline for removing support for less secure apps, and should plan the migration to the new setting in advance.
  

  Once Google disables support for Less Secure Apps in Google Workspace, the existing directory service synchronization profile Google Workspace will no longer allow users to login to MailStore as long as the authentication method is still set to IMAP.

• GPO Templates

  GPO templates are now bundled with the application. End customers may download the GPO templates from the default page of the Client Access Server. See the index.html file in the sample branding folder on how to integrate the corresponding link. As the Email Archive Client and Email Archive Outlook Add-in use the same registry keys as MailStore Server and MailStore Outlook Add-in, the GPO templates provided are those bundled with the original MailStore products.

• IMAP Access to Archive

  When using either the new Microsoft 365 (Modern Authentication) or Google Workspace directory service synchronization profile, users that have been added by these profiles cannot access their archive via the integrated IMAP server as a MailStore SPE instance is not able to verify their credentials by itself.

• Mobile Web Access

  The dedicated Mobile Web Access has been removed due to no longer supported third-party components (e.g. jQuery Mobile) and in favor of MailStore Web Access, which has been received major enhancements in terms of performance and usability.

• Legacy Web Access

  As parts of Legacy Web Access are representing the server-side of the Outlook Add-in, the Legacy Web Access is still present, but no longer advertised on the login screen of the Web Access.

• Group Policies

  The following group policy settings are no longer supported in MailStore 13

  • MailStore Client: Accept Thumbprint

    If a server name has been defined by a group policy, the certificate used by the Client Access Server must be trusted by the client computer and it must not be revoked or expired.

  • MailStore Outlook Add-in: Accept Thumbprint

    If a server name has been defined by a group policy, the certificate used by the Client Access Server must be trusted by the client computer and it must not be revoked or expired.

Upgrading to 12.1

• TLS Compatibility
  To connect to Instances in environments that support TLS version 1.1 or 1.2 only via the MailStoreCmd command line util, the Email Archive Client launcher must be updated by downloading and reinstalling it either manually or through a GPO.

Upgrading to 12

• Expired Certificates

  Irrespective of whether the certificate's trust can be verified, no connection is established by the E-Mail Archive Client to Client Access Server's whose certificate has expired or was revoked. In such a case, the certificate on the Client Access Server must be replaced first.

Upgrading to Version 11

• Upgrading Archive Stores

  Depending on the archive size this can take an excessive amount of time. On average 50.000 messages are processed per minute during the upgrade.

  Until the archive stores have been upgraded, not all functionality of the software is available. To facilitate

  • retention policies,
  • the search functionality,
  • the improved recovery records,

  the databases of the archive stores must be upgraded.

  Proceed as follows to upgrade

  • Log in to the Management Console.
  • Click on Instances
  • Select the instance to upgrade
  • Open the Storage tab
  • Right-click on an archive store and select Perform Upgrade to upgrade a single archive store.
  • Carefully read the notices and click on OK to start the upgrade process or click on Cancel.
• Retention Policies
  If not all attached archive stores are available (State: Archive here, Normal), or their status is Write-Protected, no automatic processing of retention policies takes place. Therefore verify if an archive store is set to Disabled or Write-Protected after the upgrade and change it to one of the above states or detach it completely. Please notice that only end customers are allowed to manage retention policies.
• Jobs
  With the release of this version, the service provider administrator $archiveadmin is limited to manage only his own jobs.
• Access via Integrated IMAP Server
  To access the archive via the integrated IMAP server, an encrypted connection is now mandatory. If necessary, adjust the configuration of your email clients accordingly and enable TLS or STARTTLS.
• SMTP Settings
  In order to being able to select system administrators as notification recipients in the new SMTP settings, the email address needs to be configured in the properties of the corresponding system administrator.
• Management API Commands Get-/SetComplianceConfiguration
  The property globalRetentionTimeYears has been removed from the commands. Own scripts using these commands have to be adjusted accordingly. To manage retention policies, two new commands are available: GetRetentionPolicies and SetRetentionPolicies.

Upgrading to 10.2

• Branding
  For the new responsive Web Access additional branding parameters were introduced. Please review your branding configuration after installing the upgrade. See Branding for the full list of options.

Upgrading to 10.1

• Archiving Emails
  If not all attached archive stores are available (State: Archive here, Normal, or Write-Protected), no archiving takes place. Running archiving profiles are terminated with an appropriate message. Under certain circumstances this prevents the creation of duplicate emails while archiving. Therefore verify if an archive store is set to disabled after the upgrade and change it to one of the above states or detach it completely.

Upgrading to Version 10

• Upgrade of Master Database
  To facilitate encryption of the master database it is upgraded to Firebird 3 during the first start of an instance and encrypted afterwards. This process might extend the time required for the first start of the instance by several minutes.
• Upgrading Archive Stores
  To facilitate encryption the databases of the archive store must be upgraded. Proceed as follows to upgrade:
  • Log in to the Management Console.
  • Click on Instances
  • Select the instance to upgrade
  • Open the Storage tab
  • Right-click on an archive store and select Perform Upgrade to upgrade a single archive store.
  • Carefully read the notices and click on OK to start the upgrade process or click on Cancel.
• Archives of Other Users
  These are no longer visible for instance administrators if the Archive Access (formerly knows as E-mail Preview) is blocked. Administrative functions such as deleting or renaming user archives are accessible through Administrative Tools > Users and Archives > Archives in the Email Archive Client.
• Export E-mails
  The previous change may also have an impact on export profiles owned by an instance administrator, in case the export scope contains archives of other users. As these are no longer visible to instance administrators if the Archive Access (formerly knows as E-mail Preview) is blocked, they are not taken into account by export profiles.
• Auditing
  All activities that are exclusively executable by instance administrators are displayed as Enabled (locked) at Compliance > Auditing. Irrespective of the Disabled status, all activities of instance administrators, excluding MessageRetrieveContent, are written into the audit log.

Upgrading to Version 9.x

• System Requirements
  Please ensure that your system configuration matches the updated system requirements. MailStore Service Provider Edition now requires .NET Framework 4.5.1. The E-mail Archive Client and E-mail Archive Add-in for Outlook now require .NET Framework 4.5.1 and Internet Explorer 8 or higher.
• E-mail Archive Client Compatibility
  Due to a bug in version 8.5 of the E-mail Archive Client, it cannot update itself to version 9. Therefore re-deployment of version 9 of the E-mail Archive Client is required.
• PDF Support of Full Text Search
  PDF support has been removed from MailStore SPE's own indexer. Therefore it is required to either install a recent version of Adobe Reader or an appropriate IFilter driver (i.e. Adobe PDF iFilter on the Instance Host machines.
• MailStore Management API
  The Management API is now listening on its own TCP port, 8474 by default. It does no longer support sessions, thus login, logout and cookie handling is no longer required nor supported. HTTP basic authentication must be used instead. Please make sure to modify your scripts accordingly. The API is not enabled by default. You have to activate it in the Management Role.
