Microsoft Retires Exchange Server OWA Access to Online Archives

Microsoft's April 17 announcement that OWA in Exchange Server will not support access to online archives after May 12, 2025, surprised quite a few people. However, the decision is entirely logical and is driven by falling mailbox numbers on-premises and the need to match engineering and support costs with revenue. Outlook classic continues to support access to online archives. Maybe Outlook will be the Exchange on-premises client for the future.
