MailStore Version 25.4: Support For Microsoft Exchange Server SE and Improved Compliance Features

We’d like to present a new version of our email archiving software today: Version 25.4 of MailStore Server, the MailStore Service Provider Edition (SPE), MailStore Gateway and MailStore Home is now available.

New Features in MailStore Version 25.4

With MailStore 25.4, you can look forward to improved auditing, a new export method, support for Microsoft Exchange Server SE and several other new features and improvements.

Improved Auditing

The MailStore audit log is important for security audits and helps compliance officers verify that the archiving system is configured correctly and used in line with laws and regulations, such as GoBD and GDPR. With MailStore V25.4, we have added an export and delete feature for the internal audit log. Regular exports and backups of audit logs maximize data protection and help auditors analyze the data. Once exported logs can optionally be removed to save disk space.

New Export Method

A new export profile enables the export of selected archives as signed and zipped EML files. This facilitates secure data migrations to other MailStore solutions including the original archive dates. Digital signatures protect the exported emails from manipulation. Watch out for other MailStore product announcements.

New Message Search Criterion

Administrators can now search for message IDs to identify and verify which archive contains a specific message.

Support for Microsoft Exchange Server SE

Microsoft Exchange Server SE is the newest edition of the popular Microsoft on-prem email server. MailStore 25.4 integrates seamlessly with the new Exchange Server Subscription Edition just like with any previous versions. MailStore can synchronize users and mailboxes and archives and restores email messages via built in APIs and with various archiving methods.

Further Improvements

There are several minor improvements MailStore admins will find handy, such as the automatic updates of auditor permissions, delayed removal of emails from journal mailboxes and multidrop mailboxes.

Software security is a top priority at MailStore. For this reason, several third-party components have been updated to the latest versions and the standard for Windows authentication has been changed to Kerberos.

All other changes and news will be published in our release notes.

Updated Certification: Meeting Data Privacy Requirements

As usual, the latest version of our software, Version 25.4 of MailStore Server and the MailStore SPE, has been certified by an independent data privacy expert.

The certification takes into account all relevant aspects of the European General Data Protection Regulation (GDPR) and affirms that, when used appropriately, both MailStore Server and the MailStore SPE meet all the requirements governing the processing of personal data set out in the GDPR.
