Outlook 2007 SP2 prompts me to authenticate to Sharepoint

Whenever I open Outlook 2007 SP2, I'll get a username/password prompt that has our Sharepoint server's address. No matter which known-valid set of credentials I enter, it doesn't seem to accept them. I've tried including the domain in my username and omitting it, and going through past passwords just to be sure.

If I hit ESC or just close the prompt, it will go away for awhile. However, it still re-appears from time to time.

The one thing I can think of that may be causing this, would be some sort of link to some Sharepoint content that has been removed from Sharepoint. But, I can't think of when or where this link would have been made or what to.

How can I easily troubleshoot and resolve this as an end-user?

What's the exact version of Outlook 2007 you are on (Help - About, you should see it in the first line)? The reason I ask is we had random authentication issues like this in our office and it was resolved by an upgrade to Office SP2. – N_Lindz – 2011-03-07T16:46:29.567

I'm running Outlook 2010 and don't have 2007 to test, but I've had similar issues with both versions. Mostly, they dealt with a password change that caused a conflict with cached credentials for a link from Outlook to a SharePoint site I could delete.

There are at least 4 places a link to a SharePoint site could exist. Check Mail, Tasks, Contacts and Calendar for SharePoint Lists. If you find any you can delete, that should fix the problem.

Sounds like I have to do this manually. I was hoping to avoid that. :-( – Iszi – 2011-03-12T17:57:36.477

Do you have a lot of links? Once I identify the problem, it takes my about 30 seconds to click those 4 areas of Outlook and delete the SharePoint links. – Tom Resing – 2011-03-13T19:24:50.390

I don't have a lot of links, but I have a lot of Task/Calendar entries to sift through to find those that are tied to SharePoint. – Iszi – 2011-03-14T03:15:21.763

1Update: Finally went around to check everything. My Tasks list conveniently had the culprit separated under "Other Tasks". Delete fixed it. – Iszi – 2011-03-15T14:34:12.960

@Iszi I'm glad you were able to find the link. – Tom Resing – 2011-03-16T14:36:27.500

You may solve your issue doing the following

Delete shared calendars.
Re-add calendars.

I don't have any shared calendars mapped that point to SharePoint. – Iszi – 2011-03-12T17:57:01.923
