We have an exchange 2007/2013 coexisting environment. I've been migrating a few test mailboxes from 2007 to 2013 and everything was working fine.
When I tried to change the internals and externals virtual directories to make the 2013 proxy to 2007 (http://social.technet.microsoft.com/Forums/exchange/en-US/f0ede355-d1d5-4dbd-80ea-06777ff2bedd/exchange-2007-and-2013-coexistnec-activesync-issue?forum=exchangesvrmobility
) , I certainly messed up a few things. Or maybe when I rolled back that attempt...
Now, users whose mailbox is on 2013 works fine in OWA, but Outlook clients can't connect to Exchange server. Everytime I try to create an Outlook profile whose mailbox is on Exchange 2013 it's asking for credentials.
If I dig further and try to manually configure server settings:
- If I specify the Exchange 2013 server and try a 'Check Name', it says: "Outlook cannot log on. Verify you are connected to the network and are using the proper server and mailbox name. The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete this action."
- If I specify the Exchange 2007 server and try a 'Check Name', the server changes for the fqdn of the 2013 server and it does resolve 'Check Name' process. Clicking on Next at this point completes the 'Add new e-mail account wizard". But is I try to start Outlook, I got an error saying "Microsoft Exchange is unavailable"
I'm thinking of uninstalling the Exchange 2013 server and reinstalling it, but I'm afraid of AD behavior. As I'm in prod mode, that would be the last thing to try.
I would like to know if anyone knows a way of resetting all Exchange 2013 server settings, including IIS.
