Login Issues with Outlook 2003 - RPC over HTTP

Recently my business manager has noticed that she cannot use her desktop Outlook client when at home on her home laptop. It gives her an error claiming that "your logon information was incorrect." The connection requires RPC over HTTP unless connected to a VPN. All the configuration is the same as it's always been, nothing modified. I double checked all the settings and indeed they are the settings required by our home office. Up until yesterday, according to her it was working fine from home.

I was able to connect to her account using OWA, but for some reason I cannot get it to work from her desktop. I called our home office's IT support center and they verified that the account has not been locked out or that the credentials have been changed. Any help would be much appreciated!

RPC over HTTPS either works it doesn't.
The main cause of problems is authentication type being wrong in the client, so you may want to change that. however if you don't have access to the Exchange server, troubleshooting the problems is going to be close to impossible.



Yeah, unfortunately I don't have access to the exchange server. Is there any reason why it, all of a sudden, decided to stop working? I had reinstalled the client and attempted to connect again but still unsuccessful. Thanks for your time and guidance.

Reinstalling Outlook usually fails to fix nothing at all. You have to recreate the Outlook profile. If that still fails to work then you will have to ask the server administrators to look in to it. There is little that can be done remotely without server admin involvement.

Thanks so much! I know it is difficult to advise without much information like that.
