I have a SMall BUsiness Server (with SP2) running Exchange. The server works perfectly we use webmail (/exchnage) all the time.
We decided to srtart using the mobile access and active-sync recently and have discovered an issue.
When you go to http://localhost/oma
(same with https) you get the following error:
Unable to connect to your mailbox on server Servername. Please try again later. If the problem persists contact your administrator
I have tried the following Microsoft fix: http://support.microsoft.com/Default.aspx?kbid=817379
which did nothing.
The server has 1 NIC, the default website is using 'all unassigned' as its IP, there are no host headers, the http://localhost/exchange
owa site works perfectly (and is configured using SSL).
The only error I get in the Application log is:
Unable to connect to the Microsoft(R) Exchange server SERVER. To fix this problem, verify that there is network connectivity between this server and the Exchange server. Also, verify that the Exchange server that this server is attempting to connect to is functioning properly
I have tried logging in using domain\user user@domain and just user. I can confirm that FBA is turned off, there are no other servers in this network and the Best Practice Analyzer gives me no errors, as of today (15th October) we have all updates.
Also we thought it might be slight corruption, so we deleted the Exchange directories, used the Metabase explorer to remove an entry and restarted the Exchange Servcies and got all new directories, this didnt help, didnt make it any worse either, but....
I am at this point lost for ideas, so please, any help appreciated.
