Microsoft Purview: Data Lifecycle Management-Increase in expansion limit for auto-expanding archive beyond 1.5 TB Beta
Data as of 3 hours ago (26 October 2026)
Description
Previously, auto-expanding archive mailbox expansion was supported only up to 1.5 TB, after which mailboxes would become inoperative. Archive mailboxes can now automatically expand beyond the 1.5 TB limit, ensuring uninterrupted retention and enabling scalable archive growth as storage thresholds are reached. This capability to expand archives beyond 1.5 TB will be available to customers with eligible E5 licenses.
