Although Exchange 2016 and 2019 are now out of support, some customers have purchased the Exchange 2016 and 2019 Extended Security Update (ESU). We have therefore decided that until the end of this Exchange 2016 and 2019 ESU period (April 2026) we will make an explicit update related announcement even if we DO NOT release anything for that particular month.

There are no security releases for any version of Exchange Server in April 2026, for customers with Exchange SE, or Exchange 2016 or 2019 ESU.

Please keep upgrading your organizations to Exchange SE.

    This is the last such announcement, right?

      I mean the ESU period is ending... but we might still do announcements when there are no releases.

        I think it's very helpful to know we're not waiting for a post to say there are updates - the clarity that there are no updates is the best no-update update!
