  • Improved DATEV EMA migration profile allows the timeout to be configured.
  • Improved DATEV EMA migration profile supports the adaptation of error handling using JSON control files.

MailStore Server 13.0.3


  • Improved "Ignore SSL warnings" has been replaced by "Accept all certificates" in archiving and export profiles in order to avoid confusion with MailStore's own warnings when the option is activated. The behavior itself remains unchanged, since "Accept all certificates" is an insecure setting.
  • Fixed Certificate warnings cause RunProfileArc audit log events of the type "Error".
  • Fixed Client and Outlook Add-In do not check whether certificates have been withdrawn.
  • Fixed Discontinued product Zarafa in the list of included implementation guides.

MailStore Server 13.0.2


  • Note Before updating from version 13.0.1: If Microsoft 365 (Modern Authentication) is used as the directory service type, please check whether there are MailStore users whose email addresses contain capital letters. In such a case, please contact technical support for assistance in preparing the update.

  • Fixed directory services: Incomplete list of e-mail addresses when using the Microsoft 365 (Modern Authentication) profile when the Azure AD is synchronized with an Active Directory.

MailStore Server 13.0


  • Note In accordance with Microsoft's extensive renaming of products for private and corporate customers, the name Office 365 has been replaced by Microsoft 365 in the software. All references to Microsoft 365 are to be seen as synonymous with the Office 365 Enterprise and other plans that have kept Office 365 on their behalf.
  • Note In this version, support for unencrypted access to MailStore Server has been completely removed. This also includes the option for HTTP to HTTPS redirection, which can be viewed as insecure without the use of correctly configured HTTP Strict Transport Security (HSTS).
  • Note The Mobile Web Access has been completely removed in this version. Many improvements and bug fixes included in this version of responsive web access make it an adequate, modern and secure replacement on all supported mobile devices, including support for user logins directly against Microsoft 365 and Google G Suite.
  • Note In order to manage connections to remote SMB / CIFS network shares, the MailStore Server Service Configuration now offers built-in functionality as a simple and secure replacement for the startup script method in earlier versions. It is therefore strongly recommended to replace existing "net use" commands in the startup script with the built-in functionality. A corresponding warning appears on the MailStore administrator's dashboard if the use of "net use" commands has been detected in the startup script file. Please note that the Startup Script section is only displayed in the MailStore Server Service Configuration if a corresponding file already exists.
  • Note Microsoft has announced that it will remove HTTP Basic Auth in Microsoft 365's Exchange Web Services (EWS). Since the classic Microsoft Exchange archiving profiles only support EWS with Basic Auth, a new Microsoft 365 archiving profile with support for more modern OAuth authentication and a new directory service with support for user logins via OpenID Connect have been added. Microsoft 365 customers are strongly advised to follow regular announcements from Microsoft regarding a schedule for removing HTTP Basic Auth and to plan an appropriate migration to the new profiles in advance. It should be noted that access to the archive via IMAP is no longer possible if users are authenticated using OpenID Connect.
  • Note Google announced the removal of basic authentication types for IMAP in G Suite. MailStore uses IMAP to authenticate users against Google G Suite. The existing directory services options for G Suite have therefore been expanded to support the modern OpenID Connect authentication method. Google G Suite customers are strongly encouraged to follow regular announcements from Google regarding a schedule to remove basic authentication types and plan ahead for an appropriate migration to the new settings. It should be noted that access to the archive via IMAP is no longer possible if users are authenticated using OpenID Connect.
  • Newly dedicated Microsoft 365 profiles for archiving and exporting emails using modern OAuth authentication as required by Microsoft. Please note that for technical and organizational reasons, these profiles are only available to MailStore administrators.
  • New directory services: New profile for Microsoft 365, which uses modern OAuth authentication to synchronize users via Microsoft Graph API and enables these users to authenticate themselves directly against Microsoft 365 using OpenID Connect.
  • New Directory Services: OpenID Connect added as an authentication method to the G Suite profile, which allows synchronized users to authenticate against G Suite directly.
  • New two-stage login process in client, Outlook add-in and Web Access that supports modern authentication using OpenID Connect, so that users can authenticate themselves directly against Microsoft 365 or Google G Suite.
  • New management of network shares added in the MailStore Server service configuration as a simple and secure alternative to the startup script.
  • New templates for group policies for client and Outlook add-in are now included in the MailStore Server installation.

  • Improved On the dashboard of the MailStore administrator and in the results of the profile execution, information about potentially unsecure (e.g. unencrypted, SSL warnings ignored) outgoing connections to e-mail servers or directory services are now displayed as warnings. Since version 12, such notes have already been displayed as information in the same place.
  • Improved client: Clicking on the folder path in the message view opens the folder and displays the messages it contains.

  • Fixed Web Access: Open Redirect in Dereferrer. This allows an attacker to create specially adapted links that redirect the victim to potentially dangerous websites even though the link itself points to a trustworthy resource. Affected versions: 9.0 and newer

MailStore Server 10.0


  • New Full encryption of databases and audit logs. In addition to the existing encryption of archive content and sensitive information within the databases, all databases and audit logs are encrypted from this version onwards. This requires an upgrade of the archive stores. Please read the update instructions carefully to learn more about the upgrade process and the consequences of stronger encryption.
  • New rotation of keys for encryption.
  • New email notifications about the availability of software updates.
  • New Optionally activatable function to enable MailStore Server to send anonymized usage data so that we can better understand how the software is used. The raw data to be sent can be viewed at any time.

"Extended archive stores" of the "Directory (file system)" type are automatically converted to "Internal archive stores".
  • Improved The access restrictions for MailStore administrators have been extended and are activated by default for newly created archives. MailStore administrators are no longer able to search or export archives of other MailStore users as long as archive access is blocked by the compliance setting "Archive access" (formerly "Email preview").
  • Improved The standard password "admin" of the standard MailStore administrator "admin" forces a password change after login. Please note that you can still only log in with the standard access data on the same computer.
