One of our users is getting this error for over a week now and his folders have not been updated since 1/11. We connect to exchange through http. I know our main office did some upgrade on the exchange server and since then he cannot connect. Also getting a certificate error message, asking if i want to proceed but when i click yes, it still cannot connect.
I tried the following, but did not work:
- tried to create new mail profile, but as soon as i try to connect to exchange server, it says exchange server is not available, outlook must be online. Name cannot be resolved.
- tried to log in under different username into computer, set up a different user's email address, same error, outlook cannot connect.
- flushdns and registerdns.
I have a feeling it has something to do with the certificate, when i use outlook web access, still get certificate error, but i can pull up his mail that way. (and internet is working good) And certificate error started at the same time as connection error. I tried to install the certificate in outlook, it says it was successful, but next time I get the same error, and cant see certificate installed.
Any ideas? He using Windows XP and outlook 2007. Thanks!
