Hey guys, I am not too sure where this should go, so I am placing it here. We're having an issue with two accounts that are unable to resolve their name on the exchange server. Previously everything worked normally, they were able to open up Exchange and it would check their mail no problem. Over the weekend though they began reporting that when they open up exchange, they're hit with a username/password box when opening Outlook 2003. When I have them try exchange\username and password, or ipaddress\username and password, or even just username\password, it still doesn't work. The box keeps on coming back up. When you go into the mail panel in Control Panel, and want to try and setup the account again, whenever we fill in the server information, type their name, and hit "Check Name", it says that it is unable to resolve their name. I'll swap out the path to the exchange server and put in the IP address directly, and still the same thing. I was reading around researching and found something about Cached exchange mode. I deleted their account, and re-created it disabling that feature, and their name was able to resolve immediately. Today I'm being approached that the issue is occuring again. Disabling Cached Exchange Mode doesn't do anything anymore. The funny thing is these users are still able to check their email fine using the Outlook Web Access. I've been researching this problem for hours now, and haven't found anything. Does anyone have a clue as to what this might be? If this thread is in the wrong location, mods please feel free to move it to the right place where I might have the best luck of getting an answer. Thanks!
