When I had this problem recently with Win 7 and Outlook 2010, I had to reset the cached password that was stored by the Credential Manager.
Go to the User Accounts control panel, select the Advanced tab, click on Manage Passwords and scroll to the bottom of the window, to the Generic Credentials section. You should see and entry like MS.Outlook:<username>@<exchange server>:PUT. Expand that record and Edit it and reenter the password. I suppose you could also click Remove from vault and let outlook recreate it, but I just reset the password. Once I did that, Outlook stopped prompting me for a password. Hope that works for you.

We believe it was a latency issue. An Outlook client tries to connect with TCP. If that times out, it then tries to connect via HTTPS and they get prompted. I found some references to Public Folders on a decommissioned server that I believe was hanging this process. I deleted those references through ADSI edit. At this point, it seems to have resolved our issue. I want to continue to monitor for any more latency. If I use the Performance Monitor in windows, what counters should I monitor and what should I be looking for? Are there other tools I should be using to monitor the performance? This is also a VMware machine. I am told to look at the CPU Ready to flag issues. Should I be looking for any specific stats on that? What other stats are relevant to an exchange server in a VMware environment.

I always figured we had something configured incorrectly, but the workaround of provisioning w/o encryption in online mode and then switching it over later makes it hard to justify the troubleshooting time :) I heard a report of an existing user experiencing this today and they were supposed to call me, but they must've given up and re-booted or something. ~JasonG > -----Original Message----- > From: John Grempler [mailto:jgrem...@jhmi.edu<mailto:jgrem...@jhmi.edu>] > Sent: Monday, December 06, 2010 16:09 > To: MS-Exchange Admin Issues > Subject: RE: Outlook is prompting for credentials > > That issue happened to us.
