Hello all, I have about 10 users in our company that use Macs... I am trying to provide them access to Exchange 5.5. Currently they are using OWA, and are whining about it. Any way, I have tried using Outlook 2001 for Mac and also the current version of Entourage. When configuring either of the apps, they return authentication errors. I have verified that all user information provided is correct. Any ideas or pointers you can throw my way? I have read many articles, but nothing appears to resolve the issue. They are able to contact the Exchange servers on the network. Regards, Chris Wall
