Microsoft Purview: Data Lifecycle Management – Increase in expansion limit for auto expanding archive beyond 1.5TB

Originally posted by Microsoft Apr 24, 2026 Uncategorized 0 Comments

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 will be offered as a consumption‑based feature for auto expanding archive beyond 1.5 TB and will be billed at $0.25 per GB per month (or $0.0082 per GB per day).
