  • Can you post the détails of the 4001 error message?

    Does it look like this:


    "Event ID = 4001

    Source = MSExchange System Attendant Mailbox

     A transient failure has occurred. The problem may resolve itself in awhile. The service will retry in 56 seconds. Diagnostic information:

    Could not find any available Domain Controller.

    Microsoft.Exchange.Data.Directory.ADTransientException: Could not find any available Domain Controller."


    If so, it may be a domain controller that just stopped working, or network connectivity that just stopped working. Could be as simple as a Layer 1 cabling problem.

    Can you ping your domain controller(s)?

    Are your domain controllers functioning OK?



    In the EMS, you can run this command to see if all essentials services are running:


    You could also run the Exchange Best Practices analyzer for a more genral view fo what's working or not.
