I am experincing an issue with a user unable to access OWA from outside the organization. When she attempts to authenticate, she receives the following error message:
"You do not have the permissions required to access this Web site. Please contact the Web site administrator".
This user is able to access OWA internally. In our environment, we have an ISA server brokering connections to the Exchange server when requests are made from the outside. I have granted this user rights to log on to the isa server. I have compared her group membership to all of the other external OWA users, and they are the same. I am missing one small, but important piece to this puzzle.
Any information that could be provided would be greatly appreciated.
