Recently, I've export some reports regarding the send on behalf rights in Exchange 2010.
However, I found out there're some unknown from my end as below.
I've got a mailbox, which has been granted to someone to have send on behalf rights as shown below.
But if I use powershell to find out the rights from this specific mailbox, it will turn out like this. There's a distribution list was granted to have send on behalf rights as well. The question is why I cannot see this from GUI as the above screenshot? If I do not use powershell, is there any method to remove it from GUI instead? Please advise and many thanks!
