I'm having some difficulty with Microsoft Exchange Server 2007 and
Thunderbird 2.0.0.x. First, I was getting a "There was an error
copying the message to the Sent folder. Retry?" error, so I created
the "Sent" folder. Upon doing that, however, I get a "Mail server ...
is not an IMAP4 mail server." I click on Cancel and then get this:

Unable to save your message as draft.
Please verify that your Mail & Newsgroups account settings are correct
and try again.

Any ideas?

Hmmm. Try another IMAP client & see if you have the same results. This won't
be a server-side issue, I think.
