Recovering email data in Microsoft Exchange Server is important to deal with issues like database corruption, accidental deletions, or server problems.

Microsoft also is advising customers who rely on the on-premises version of Exchange to move to the 2019 version as soon as possible. Microsoft will support Exchange Server until October 14, 2025.

Microsoft says customers should ensure their Exchange server patches are up to date to prevent cyber criminals from deploying BlackCat ransomware.

Microsoft is giving such organizations a one-year grace period. Microsoft wants Exchange Online users to switch to Continuous Access Evaluation instead of using Client Access Rules.

In the Cached Exchange Mode, a copy of your mailbox is saved on your computer. The copy offers prompt access to your data and is often updated with the server that runs Microsoft Exchange.
