When I try to send a message from User B's mailbox as user A, the message is sent "On behalf of" and not "as" User A.
Do I need to deny "send on behalf of" for User B on User A's mailbox? If so, how?
Thanks

The only way you can send it without it being sent "on behalf of" is to create an additional profile and mount that mailbox directly in Outlook. You can have multiple Exchange accounts in a single profile in Outlook 2010 but not Outlook 2007.

I believe what you want is:
Add-ADPermission -Identity 'CN=User Name A,OU=path,OU=path,DC=domain,DC=com' -User 'domain\UserB' -ExtendedRights 'Send-as'
That *should* work without the 'send on behalf' bit.

This is straight from TechNet
To use the Exchange Management Shell to grant a user the Send As permission for another user's mailbox
I cut and pasted (and obfuscated) the command above from a successful test that I just performed on our 2007 system.

I believe you also have to give userB "send as" rights separately in the permission settings for userA's AD account in order for it to work without the "On behalf of" appearing on the final message.

Enphyniti: I did as you recommended and this is what I received:
WARNING: Appropriate ACE is already present on object "CN=User,OU=,OU=,OU=,OU=,DC=,DC=l" for account "Domain\User".
If I go through "Exchange Console - Mailbox -User A - Properties - Mail Flow Settings - Delivery Optons", Send on Behalf of permissions are shown there. If I remove User B from this permission, grant user B "Send as" access via Shell as stated above, I get the following error:
"You do not have the permission to send the message on behalf of the specified user"
