Overview

Archiver 15.14 has been released and is available for download.

Release Date: September 17, 2026

New

• Added support for archiving Microsoft 365 (Exchange Online) mailboxes through Microsoft Graph, ahead of Microsoft's retirement of Exchange Web Services.

Fixes

• Microsoft sign-in settings and the archive security key are no longer lost when Archiver is repaired or reinstalled.

• The maintenance wizard now offers a Repair option, so continuing through it no longer removes Archiver.

• Archiving no longer stops with an incorrect licensed-user error when Archive Restrictions limit archiving to selected users or groups.

• Archiving is no longer skipped for some messages when Archive Restrictions are set to archive if any owner is in the list.

• Archive alerts are no longer raised when a backup snapshot runs at the same time as archiving.

• The Administration interface no longer takes a long time to load when user access rights include deleted users.

• Archive Assistant settings can be applied again — Use Default Settings and Customize Settings no longer stay stuck.

• Exports to PST now report a clear error when a search returns incomplete results, instead of stopping partway or finishing with only part of the messages.

• Fixed a failure when restoring email owners on Microsoft SQL Server archive stores.

• The new web interface now displays correctly in offline and air-gapped environments.

• Corrected the German wording of the Access Control status on the Configuration page.

• Bulk Schema Upgrader no longer fails with an empty database list after upgrade.

• Fixed stored cross-site scripting vulnerabilities in the administration and reporting interface (CVE-2026-48530 to CVE-2026-48539) - Reported by Alex Williams (Pellera Technologies).
