Microsoft has reminded admins that Exchange Server 2013 is reaching its extended end-of-support date in 60 days, on April 11, 2023.
The first version of Exchange Server 2013 was released in January 2013, and it reached its mainstream end date four years ago, in April 2018.
"Exchange Server 2013 will continue to run after this date, of course; however, due to the risks listed above, we strongly recommend that you migrate from Exchange Server 2013 as soon as possible," the Exchange Team said.
"If you haven't started your migration from Exchange Server 2013 to Exchange Online or Exchange Server 2019, get going now!".
"If your organization chooses to migrate mailboxes to Microsoft 365 but plans to keep using Azure AD Connect to manage user accounts in Active Directory, you need to keep at least one Microsoft Exchange server on-premises," Microsoft says.
"If you remove all Exchange servers, you won't be able to make changes to Exchange recipients in Exchange Online because the source of authority is your on-premises Active Directory."
