I gave a user full access to her boss's exchange SBS 2003 Exchange account a few months ago (with his consent!), so she can view his email as another account in Outlook while he was away on a trip.
The weird thing is that even though I have now removed her permissions - by changing the Exchange Advanced tab under the bosses account - she still has access to his email through Outlook. She isnt in any security groups (so far as I can tell) that give her this access and I cannot trace how it is happening.
Is there a way to discover how she is getting this permission?
