    Hello,

     

    soooooo.... The problem seems to be resolved. After the restart there are no more Event ID 9042 messages on the Exchange server.

    I still wonder why we can't figure out which mailbox was skipped and why. Why isn't this logged somewhere on the exchange server..?

Hello AnnTaeYoun ,

 

I changed the logging level as suggested. Unfortunately, I can't see anything helpful in the logs, there are no new errors, warnings or info that tell me where the problem is. Or what error the assistant has.

 

The log in the Exchange installation folder looks the same as yesterday. And there's nothing obvious in the event viewer as well.

 

 

I will change the logging level back to the standard. Anything else I can try?

 

Thank you very much.
