    I tried all the above options but still the migration wouldn't start.

    Strange thing is that it already run once without any problems. Can you please contact me to fix the problem?

    Same issue as Nero Blanco,

     

    Just got blasted with a wall of :

    Your migration failed while checking source credentials. Unable to flush accumulated pending requests = 11. UnauthorizedSharePointException: Cannot Flush Client Context: The remote server returned an error: (401) Unauthorized. ---> WebException: The remote server returned an error: (401) Unauthorized.

     

    On a bunch of accounts that the credential verification worked fine on.

     

    Not sure why.
