I Have two DAG members in Exchange 2016 with 3 DB, MB01, MB02, and MB03.

MBO3 Active Copy of First Server gives below error in ECP:

"The Microsoft Exchange Replication service encountered an error while inspecting the logs and database for MB03\EXC01 on startup. Error: File check failed: Logfile 'G:\MB03-Log\E0300000004.log' was not found."

Is it an urgent problem? What must I do to solve this?

    Hi,
    Check the storage location, is the log file missing? Did you manually delete it?
    Run the following command to check the mailbox database copy status and post the result:

    Get-MailboxDatabaseCopyStatus -Identity DB1 | Format-List  
    

    Can you find any related error in Event log?

    Hello,
    The log file "G:\MB03-Log\E0300000004.log" is not there really, it is lost. All filenames in that directory like "E03000007**.log" .

    The Get-MailboxDatabaseCopyStatus command results below:

    See my previous question:

    Are you running any anti-virus software on those servers? If so, make sure you are excluding the correct things

    Thank you, Andy David.
    Is there a risk of doing this process on Exchange? I am not so Experienced so should I be irritated?
