Outlook 2010 Permissions to send on behalf of???

Windows 7 Pro SP1, Exchange and Outlook 2010
We've an admin asst who has gotten a new pc today.  She didn't have this problem before she got the new pc.  She's reporting that when she sets up a new meeting, the invitation looks as if it's coming from her, rather than her manager.  Would someone clue me in on why this may be happening?

Outlook\Exchange is not my strong point so in searching for a solution I came across this link and several like it.  It seems that the owner of the mailbox\calendar, etc delegates permissions to whomever.  That nothings done on the admin asst's side of the fence so to speak.
If you need more info please let me know.  Thanks for your time and consideration.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Send on Behalf of is when the email specifically states "Sent on Behalf of username". If you want this to completely appear as if it was coming from the other users mailbox then you need to provide Send As permissions, and not "Send on Behalf Of"

Send As permission is specifically an AD permission. Send on Behalf of is an Exchange specific permission.

Also see the link below which outlines how to enable Send As permissions

changes can be made on the exchange side.. When she setup outlook her previous permissions should have carried over.-+
