Greetings, We have an issue that has arisen with our Mac users after we upgraded to Windows 2003 SP1. We are running exchange 5.5 on a windows 200 server and all has been well until the DC's were upgraded to Server 2003 SP1. Now all Mac clients logging into outlook 8.1 (Most are running OS 10 in classic mode) get an error stating "The logon credentials were incorrect. Make sure your username and password are correct and try again." The problem is that their username and password are correct, and regardless of what user tries it they get the same error. Eventually the user's AD account gets locked out for failed attempts. So its getting to AD just not authenticating correctly. If anyone can help me I would appreciate it. Thanks again.
+++++++ Correction!! We are running Outlook 2001.

Thanks again. > > Hi Brandon! I don't know the answer, but this sounds very much like a security setting. Could possibly be a Group Policy set too high or requiring some sort of digital signing, which Macs (especially Mac OS 9 and earlier) can't do. Be sure to look through the domain group policies. Hope this gets you started in the right direction! bill -- William M. Smith (Microsoft Interop MVP)
