Hi,
we are not able to connect to our exchange2000 server via imap4 or pop3.
Both protocols are configured.
SMTP & MS-OWA works fine from outside and inside lan.
imap4 nor pop3 are working inside lan or outside.

a telnet to the exchange server on port 143 (imap4) show the right reaction
of the system.
but login fails..
anyone an idea ? It's for sure not a firewall issues, because it doesn't
work also from inside lan

thx

If the users Windows 2000 Logon Name is different to their Exchange 2000
alias, then they need to configure their client to provide their logon
creditials in the following format:

w2kdomainname\w2klogonname\e2kalias

They are identical, when I'm using Outlook with a direct connection to
Exchange Server, not additional identification is done.
My Windows account is connect to Exchange information, by using AD

I'm having the exact same problem. I read Mark's responses and neither of them applies to me. My Windows (pre-Windows 2000) user ID
and my Exchange alias are both the same (jjohnson). I even made my AD logon "jjohnson." (It was previously blank.) The KB article
was not helpful, because the registry value was set to 0, not 5.

When I TELNET to my server for POP3 I see this:

user jjohnson
+OK
pass <blah blah>
-ERR The requested mailbox is not available on this server

When I use OE to attempt to access IMAP, I get

There is no replica for that mailbox on this server.

If I try to refresh my IMAP folder list, I get

Any suggestions? For reference, we migrated Exchange 5.5 mailboxes to this new Exchange 2000 server, if that sends up any red flags
for people.

It appears my issue was with IP addresses. I had a host table entry which pointed to the old class C address instead of the new
class A address we have switched to. I removed the entry and restarted OE and everything's fine.
