Version 25.1 of MailStore Server and the MailStore Service Provider Edition (SPE) are now available.

 

Increased Security and Support for Microsoft Server 2025 and Microsoft Outlook 2024

In MailStore version 25.1, we have removed outdated Microsoft C++ runtime libraries to eliminate potential security risks. However, this means that old MailStore databases (Firebird Version 2.5 and 3) must be updated before you can use MailStore Version 25.1.
MailStore version 25.1 also supports the new Microsoft Server 2025 and Microsoft Outlook 2024. Use the MailStore App for this. For older Outlook versions without app support, you can still use our well-known MailStore Add-in.

Important note: Before installing MailStore version 25.1, you must update your MailStore databases (both the master database and the internal archive stores for email data) to Firebird 4. If you do not update your databases to Firebird 4 and install MailStore Version 25.1, databases can no longer be loaded in MailStore Version 25.1. An update to Firebird 4 is only possible with MailStore Version 24.4, MailStore Version 24.3 or MailStore Version 24.2. Please also read our message on this topic.

The following instructions will show you how to proceed:

As with other new versions, Version 25.1 is, of course, certified according to IDW PS 880 (DACH region only) and the EU’s GDPR.
