Hello everyone,
I am trying to backup mailbox by commvault , but job went to pending in 5% , i checked the logs i found the following message
"Exchange auto discover for CAS server for administrator failed with error [The remote server returned an error: (401) Unauthorized.]"
already assigned full permission for services account. this issue occurred suddenly earlier it was worked fine.
Also i checked commvualt docs and followed their guide , still same error when ran job again.
thank you
