Microsoft Purview: Data Lifecycle Management-Auto-Archive for Exchange Online Beta
Data as of 2 hours ago (26 October 2026)
Description
A new capability called Auto-Archiving for Exchange Online will enter public preview in November 2025 (currently under private preview for selected customers). When a user's mailbox utilization exceeds 95% of its quota and archive mailbox is present, this feature automatically moves the oldest items excluding those tagged with “Never Move to Archive” from the primary mailbox to the archive mailbox to prevent mail flow disruptions by keeping usage below the safe threshold of 95% of mailbox quota.
Change history
Added to the roadmap 23 December 2025. Tracked here since 1 September 2026. Earliest target we recorded: February 2026 (since tracked — Microsoft may have moved it before we started watching).
