Greetings from Red Cross Germany!
We have an exchange server 2013 with a connection to Microsoft 365 running locally on our network. We use Windows Server 2012 R2.
This exchange server should now receive the cumulative update CU23. Unfortunately, the update process did not go through properly and the Exchange server services are no longer available locally.
The installation ended with error 80040667
Already googled possible workarounds unfortunately did not provide a solution.
