exchange online archiving

The exchange online archiving tag covers Microsoft Purview’s expanding archive capabilities in Microsoft 365, with particular attention to storage limits, retention, compliance, and licensing. Current coverage centers on Microsoft’s planned July 2026 increase to the auto-expanding archive ceiling beyond 1.5 TB for eligible E5 customers in worldwide multi-tenant environments.

It also highlights the practical distinction between a higher technical capacity and continued E5 licensing requirements.
