  • Hi Mahfuz,

    If your Exchange server is working fine and still getting this error message, Kindly check and verify Microsoft recommended Exchange file,folder and process are excluded in  Antivirus.

  • Hi,

    What's the detailed information about your Exchange server version? What changes have been made recently which may be related to the issue, such as changing certificate.

    I searched the below similar threads about your issue above:

    Event 146, Cannot log into OWA or ECP

    Please Note: Since the web site is not hosted by Microsoft, the link may change without notice. Microsoft does not guarantee the accuracy of this information.

    Check your bindings in IIS, make sure 443 binds to the certificate you are using and 444 binds Microsoft Exchange certificate

    And this: We are getting this recurring event ID on our MSExchange OWA / Id: 146 Exchange 2013

    The error states the user doesnt have an exchange mailbox, it may be a AD user and have disconnected mailbox.
