Microsoft Exchange Online Archiving Annual

Keep email history available without expanding on-premises storage with Exchange Online Archiving for Exchange Server Annual. This subscription adds cloud-based archiving capabilities to Exchange Server environments, helping organizations retain mailbox content for compliance, legal discovery, and operational reference. It is designed for IT teams that need a controlled way to extend message retention while keeping primary mailboxes on Exchange Server. By separating active mail from archive storage, it can reduce pressure on local infrastructure and simplify long-term retention planning. For regulated organizations, archiving is not optional. This license supports a more disciplined records strategy by keeping older messages accessible while preserving the performance of the primary mail system. The annual NCE model also gives procurement teams a clear renewal cadence and a straightforward way to align archiving coverage with user counts and retention policy requirements.
