Upgrading Exchange Server causes the server to go offline unexpectedly

Symptoms

Using the setup wizard to upgrade an Exchange Server to a newer Cumulative Update causes an Exchange server to be marked offline in Exchange Active Monitoring during prerequisite analysis and prerequisite installation. If the setup wizard isn't advanced to continue the upgrade process, the server will remain in an offline state until the setup is allowed to proceed. Also, if any of the setup /Prepare* switches are used to update Active Directory on a functional Exchange Server, the server is marked offline in Exchange Active Monitoring.

Cause

This issue occurs because the setup puts the server in an offline state before the binary upgrade process is ready to proceed. 

Resolution

The setup will delay and make a server offline until the binary upgrade process is started.  

For Exchange Server 2013

To fix this issue, install Cumulative Update 14 for Exchange Server 2013 or a later cumulative update for Exchange Server 2013.

For Exchange Server 2016

To fix this issue, install Cumulative Update 3 for Exchange Server 2016 or a later cumulative update for Exchange Server 2016.
