Why is Outlook prompting for Username, Domain, & Password?

[mcnuttz]

Good afternoon....

This looks like a nice forum y'all have here. I've searched through the archives, but I haven't been able to find a solution to a problem that one of my users is having.

First off, we're running Exchange 2000, and this particular user is using Office 2000. Everytime he goes to open his Outlook, he is prompted for a username & password. It is the same username & password that he uses to log on to our network.

Can someone please tell me how I can get rid of this? He seems to be the only person in our organization who is having this problem, but he's starting to get a little heated about it.

Thanks for any help that you can offer.

This shouldn't happen by default. It usually indicates one of two things:

1. His account is locked out. If he can logon and access network resources without a problem then this isn't the case.

2. The Exhange Server authentication settings are "incorrect" in his Outlook Profile. Check to see if it's set on "None". If it is, change it to NT Authentication. This should pass his credentials through automatically.

If it's not either one of those then we'll need more information to help.

I remember checking that setting and it was set to NT Authentication.

This problem has me totally lost.

Thanks for your help.

Is this user's account the primary account for the mailbox? This may be a dumb question, just trying to brainstorm.

I work for the government and therefore am a little behind the times with my exchange server (still on 5.5--please hold the laughter), so I don't have much experience with EX2000.
