I posted a question previously about this and the solution worked, however it isn't really a solution at this time. I'm trying to grant John permissions to send as (send on behalf) of sales in Exchange 2007. I have given the following command in the EMC as well as in the gui to give Send as permissions and Send on Behalf of.
Add-ADPermission "sales" -User "john" -Extendedrights "Send As"
The way I am having John send as sales is to put firstname.lastname@example.org in the From line in Outlook. He then receives the Exchange Delivery notification that he doesn't have permission when attempting to send as sales. The only way I can get it to work is if I recreate the Outlook profile. Unfortunately this isn't an option with this user.
Is there something else I can do? It's been over 24 hours so I know the changes have replicated.
