Can not receive emails on Thunderbird

[goude]

Hello everyone

I'm using fedora 11 and I have set up my thunderbird as IMAP to get emails from a microsoft exchange server.
All of sudden today when I click on my Inbox I get the error:

The current command did not succeed. The mail server responded:
[TRYCREATE] The requested item could not be found.

Also I noticed that I can send emails but not receive.
Does anyone know a fix for this? I haven't changed anything at all.
Any suggestions please?

Thanks a lot

I could be that the administrators operating your exchange server may have turned off IMAP4 access, or it could have been turned off by an update or other change. Check with them.

Thanks for your reply Roxoff,

IMAP4 was on and asked them to restart it. It fixed the problem.

Thanks a lot for your help
