Microsoft Exchange System Attendant failed to read the membership of the universal security group '%1'; the error code was '%2'.
The problem might be that the Microsoft Exchange System Attendant does not have permission to read the membership of the group.


If this computer is not a member of the group '%1', you should manually stop all Microsoft Exchange services,
run the task 'add-ExchangeServerGroupMember,' and then restart all Microsoft Exchange services.
