Exchange lockout with correct credentials

[joshmindham]

Good morning,
We are using Outlook 2003 with Exchange 2003, and one of our users is having a problem, as such:

When she goes into Outlook, it prompts her for her credentials, as she wished to happen. She enters her domain credentials and it lets her in. She closes out of Outlook or keeps it open in the background. The next time she logs in, or during a random Send/Receive, it asks for the credentials again. She re-enters the same credentials she not only logged into the domain with, but also logged into the same outlook session with a short time ago, and it tells her that her account is locked out.

We go into the active directory, and the account is not logged out on that end. We tell her to check again, and she is able to get in once more. This only began happening over the course of the last couple days. She is using Kerberos/NTLM Password Authentication, and it should be synched up to her domain credentials, as always. She is the only person in the entire domain that this is happening to. Does anyone have any tips/advice on how to resolve this issue?

Thank you for your time,
-Josh Mindham

It sounds like her password has expired and that she is only closing Outlook and NOT logging off from the workstation. I would make sure she has logged off completely and even reboot her computer.

I have users who just lock their workstations and never actually log off. Then their passwords expire and they experience the problem you are describing.

Thank you for the suggestion. Her password was set never to expire, and we had in fact reset her password for her. I have watched her reboot, and she logs out completely at the end of the day, yet the issue persists. We've even tried clearing her cache in the hopes that this would fix it.

It is just bizarre that exchange would take her password once, send/receive as usual for a while, request her credentials again sometime within the next 10 minutes (it checks for new messages every 2 min), reject her credentials, tell her that she is locked out, then accepts the exact same credentials 2 minutes later.

Is there a local file on her machine that we should be looking at, since it seems like Outlook/Exchange is storing and/or sending credentials incorrectly?

THe user may have the cached passwor saved. Go to Control Panel- User Account - Advanced. Delete all the stored passwords there.

I have also seen this issue resolved by creating a new Outlook profile.
