I guess my statement wasn't clear. I meant is it possible to disable non-HTTP protocol support. If it can be enabled/disabled perhaps that is what my issue is. I don't see anything obvious though.

I see what you mean. It will take me a while to figure out the proper command to use. I've actually made some progress this morning. As it turns out, it appears that RPC over HTTP does work properly. Authentication can sometimes take a lot longer that I would expect, but otherwise it functions as expected. Unfortunately I still can't get regular non-HTTP connections to work. If I switch from a configuration using RPC over HTTP and turn that setting off, loading Outlook immediately says it can't connect to the server and gives you that standard Retry/work offline/cancel error. Is it actually possible to disable that protocol on the server end? The problem has to be a configuration mistake on the Exchange server. From: Michael B.

The POP3/IMAP errors were red herrings and have nothing to do with the Outlook connectivity issues. It's definitely baffling though. What event logging categories might be helpful in determining what's going on? I took a look at them and nothing really jumped out.

The Get-ExchangeCertificate on the server shows IP.WS on the SAN Cert, so I guess that's correct as well. When I try setting up Windows Mail in POP3 mode, I get the error: Account: 'exchange2.acadiau.ca', Server: 'exchange2.acadiau.ca', Protocol: POP3, Server Response: '-ERR Command is not valid in this state.', Port: 110, Secure(SSL): No, Server Error: 0x800CCC90, Error Number: 0x800CCC91 With an IMAP connection, I get the error "The server has rejected your login. Please verify that the username and password are correct." I tried setting the event logging for POP3 and IMAP to highest, but I'm not getting any authentication errors listed. What event service controls logging for authentication requests? I didn't see anything obvious in the list of possible event categories. Maybe it will have a better explanation of why the server is rejecting the logins. From: Michael B. Smith [mailto:mich...@smithcons.com] Sent: May-13-10 10:34 AM To: MS-Exchange Admin Issues Subject: RE: Outlook won't connect to Exch2010 Doesn't matter whether you delete it or not. "Most" people run with the default cert for SMTP and a SAN cert for everything else. If you run a Get-ExchangeCertificate, you need a "W", and a "S" on valid certificates. The others ("I", "P") are secondary to the first two. I'm kinda at a loss. You might try those same tests from a workstation that has the management tools installed, instead of from the Exchange Server itself. Regards, Michael B.

If I tell it to ignore the certificate validity check, then it also work. The detailed error is: "Host name acadiau.ca does not match any name found on the server certificate e=r...@acadiau.ca, CN=www.acadiau.ca, OU=Technology Services, O=Acadia University, L=Wolfville, S=Nova Scotia, C=CA" It would imply that it expected to find acadiau.ca or www.acadiau.ca in the cert, but I'm not sure why it's using those entries. My UC cert has three entries and they appear to work properly for the other tests, and in OWA. We never had a cert on Exchange 2003, but the UC cert I got from Digicert seem to install properly. I don't reference www.acadiau.ca anywhere as far as I know. The problem I'm encountering is that Outlook (any version) won't connect to the server. As I started troubleshooting, I've also discovered that POP3 and MAPI connections fail as well. The only way I can connect to the server is using OWA or through my iPod Touch. I'm pretty sure this whole problem occurred when I installed the UC cert, although I'm not 100% sure. I had been using OWA for my testing so I didn't notice when Outlook broke. I suspect it's going to be another one of those situations where I need to check some box some place. It's just not obvious what needs to be done. From: Michael B.

When the server install was first completed, one of the first things I did was create a test account and connected to it using Outlook. It worked as expected. OWA also worked fine, as did access to the account from an iPod Touch. When Outlook tries to verify the user account, it says it can't connect to the Exchange server. One thing I've done since the install was completed was install a UC certificate and it works as expected with OWA. Being paranoid I removed the UC cert and assigned services back to the default Exchange cert, but that didn't help. At this point I'm not even sure if it's a certificate problem. I tried setting up Windows Mail using both POP3 and IMAP protocols, and both of those protocols failed as well. The error message indicates that the server is rejecting the username/password but since I know I'm using the right credentials there's obviously something else happening. What would allow OWA to work but break everything else?
