Outlook 2011 for Mac issue with autodiscover

i have about 15 macs in my environment and here is the issue i am running into with Outlook 2011.  The macs connect internally to the exchange server no problem.  When a user takes the mac outside of the network, autodiscover works like it is supposed to and changes the Exchange server URL to the external URL and outlook continues to work.  The problem is when they bring the mac back into the network, autodiscover is not changing the URL back to the internal address.  i am aware of the workaround by disabling autodiscover on the macs but was hoping that someone knows how to actually get it to switch back and forth properly.  My windows machines have no issues doing this.

"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.


I have also an environment with Exchange Server and MacOSs, but I have 2 DNS servers: one for inside my network, one for outside my network. So my clients receives 2 different IPs for the same URLs, depending where the client is: inside or outside. I never had any trouble.
