Sometimes Microsoft Exchange 2010 Management console get stuck and tries to connect to the wrong server instead of the one you are logged on to.
If it is only connecting to the wrong server (but connecting) you can simply right click on “Microsoft Exchange On-Premises (ServerName)” properties and select the server you want to connect to.
However things get more complicated if the server it is trying to connect to no longer exists or is orphaned. In that case you cannot right-click properties and this will yield your management console totally useless
To fix this follow the below steps
- Close EMC
- Browse to C:\users\%username%\AppData\Roaming\Microsoft\MMC\ and delete the file called “Exchange Management Console”.
- Using your favorite registry editor go to HKCurrentUser\Software\Microsoft\Exchangeserver\v14\AdminTools\ and delete the value NodeStructureSettings
- Now run Exchange Management Console again and your problem should be fixed
