Unable to connect to exchange 2003

[stheologo]

Hi,

I have just installed Zimbra desktop. I have tried to set it up to connect to the exchange server. I get an error that says please check host or port.

I am unable to telnet to port 143 or 25, but my Microsoft Outlook Client works. I can ping the server.
Am I missing something here?

Is it possible for Zimbra desktop to connect through Exchange OWA

Thanks

Outlook doesn't use IMAP for communication with Exchange. Please make sure your sys admin has enabled IMAP on Exchange.
