Is it possible to add an AD security group to a mailbox with Send On Behalf permissions? I have been trying to do this via powershell with the Set-Mailbox command (Set-Mailbox Mailboxname
-GrantSendOnBehalfTo @{Add="GroupName"}) but I keep getting an error that it cannot find the object (groupname) and make sure it's spelled correctly. I know my groupname is spelled properly. I've checked the PublicDelegates in ADSIEdit and there are no old user ID's here. Just wondering if it's because I'm trying to add a security group instead of users, and security groups are not allowed.
