Add me to the list! I've spent over a week looking over the documents on this site and others to resolve my issue!
Outlook will not connect to the exchange server. I have followed the instructions in the Microsoft documents and those tips provided by Sembee. I feel I'm close but I need help getting over the hump!
I have a front end server, back end server and two domain controllers. I have tried both the manual registry entries and the RCP-HTTP FRONTEND/BACKEND" check boxes in Exchange System Manager. Right now I am in the latter config. I have a valid certificate provided by FreeSSL. The test of hitting https://server/rpc
works, I get the 401.3 error after three login attempts. OWA works great.
When I run outlook with the /rpcdiag switch, I see the below two lines and get prompted for a username:
Server Name Type Interface Conn Status req/fail avg resp
--- Directory --- Connecting
xmail.domain.org Referral --- Connecting
When I check the security log on the front end server, I see successful logon events along with subsequent logoff events.
I'll leave this initial question with that, I can provide more info if necessary. I'll be here all day working on it! Thanks in advance.
