Error

Hi,

I have deployed Exchange 2013 co-existence with Exchange 2010, Currently doing migrations and now we are getting below error. When I try to access other user mailbox (B) from Account (A) which is having full permission on mailbox B.

I tried by reset attributes and inherit permissions but, issue still persists....
