Only ONE Outlook 2010 installation "Cannot connect to Exchange server" when setting up new profile

  • 772

I have a single server Exchange 2010 installation - OWA Connectivity has been confirmed, Autodiscover is configured and working properly for EVERY other installation. Other user accounts tested on problem Outlook, none can connect. Windows Firewall is pre-configured by Group Policy, only modifications being related to remote management. Firewall has also been disabled during diagnostic period. Network discovery and file sharing is enabled on workstation as well. Windows 7 Professional, latest updates installed.

Driving me nuts. Help, serverfault?

    Here's what really happened.

    There was a bug in Update Rollup 5, prior to SP1 that was causing this issue to occur. After applying SP1 and subsequent updates to Exchange, the issue went away, and has not cropped up again.

  2. My comments aside, this definitely appears to be a workstation problem. Any chance of wiping this workstation and starting from scratch?

  3. Things to check ((Assuming you're already discarded connectivity issues: access to exchange, test port with telnet)):

    • Test Autodiscover on the troubled host, here's an offline tool for that (read more here).
    • DNS (Flush your DNS (ipconfig /flushdns, /registerdns).
    • You say the machine is getting settings from GPOs, I'd be tempted to do a result and cross reference with another working machine... also check the OU this machine was added to (Not sure specifically how this would matter to you though, you're going to have to assess what settings the machine is supposed to be getting).
    • There is no real good way (that I know) to be 100% that your Outlook client is installed properly. I'd also be tempted to repair the install, or even uninstall and re-install outlook.

    Don't you love it when similarly (or identically) configured machines, that are supposed to work the same, somehow don't?... Well, the nice thing is that you have a known working configuration, and this box's issue just happens to be an anomaly. Remember to reboot a few times after forcing a gpupdate, if you're needing to fix GP settings, or repairing the software... or try a new user in case this user's profile is corrupt somehow.

  4. You're not seeing this error message are you?

    An unknown error occurred, error code: 0x80070057 http://support.microsoft.com/kb/2028193

    Even though the hotfix description mentions Outlook 2010 connecting to Exchange 2003, I had the exact same issue a few weeks ago on a brand new Windows 7 install, with Office 2010 Home & Business installed - connecting to a SBS2011 server (Exchange 2010). The profile setup wizard at first-run would just bomb out with an error.

    I ended up creating the profile manually through Control Panel/Mail, and chose to specify server settings manually.
