Password Prompt in Outlook 2003

Not open for further replies.


I work for an IT firm. and one of our client companies is having an issue which recently started as of Friday of last week. Here is what is happening.. The client company used to be able to just log in to outlook 2003 and it wouldnt prompt them for their outlook password. Now since Friday of last week,every so often when they log in or hit send and receieve or other functions within outlook.. It will prompt them for their password.... They are using Windows XP Pro. Outlook 2003.

They are using kerberos/NTLM authentication.



What version of Exchange are they connecting to? If they put in there password does it stop prompting? What SP level is Outlook?


They are running SP3 on the 2003 outlook. They dont have to input their password. Its automatically saved. If they hit cancell it goes away.. sometimes to come back but sometimes it doesnt.. i am still trying to determine what version of exchange they are logging into. They are not one of our normal clients so We dont have access to their server....


Without have access or knowing what version of Exchange this could be hard to troubleshoot. Is it happening to everyone? Can you verify that they are connecting to Exchange via MAPI and not POP/IMAP? Any updates applied to server or desktops?

Does the issue occur on certain Outlook client or each client?

If the issue only occurs on certain client, it may not be related to Exchange Server. It can occur by corrupted Outlook profile or incompatible third party programs. I would like to share you the following article to troubleshoot the issue.
