We have created one User and assigned with the Mailbox to the User , the
role was not assigned to the user .
We removed back the Mailbox and assigned it back again to the user but
the mailbox is not getting created for the user.

Checked the server logs we could able to get this error in the logs .

Could you please suggest what may be cause for this error reported.
