how concerned do I need to be about this error in even viewer ?
Microsoft Exchange System Attendant failed to read the membership of the universal security group '/dc=RILOT/ou=Microsoft Exchange Security Groups/cn=Exchange Servers'; the error code was '8007203a'. 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 '/dc=RILOT/ou=Microsoft Exchange Security Groups/cn=Exchange Servers', you should manually stop all Microsoft Exchange services, run the task 'add-ExchangeServerGroupMember,' and then restart all Microsoft Exchange
services.
