Outlook in a Terminal Server session hangs when the TO button is clicked
You are in a Terminal Server session and when you try to hit the TO button in Outlook to add an email address, Outlook hangs.
This happens because the Microsoft Exchange Address Book service has stopped responding. If you check the Exchange server, you may see the following entry:
Watson report about to be sent for process id: 3376, with parameters: E12, c-RTL-AMD64, 14.01.0270.001, M.E.AddressBook.Service, unknown, unknown, M.E.Common.ExServiceBase ServiceTimeoutException, 0, unknown.
To resolve this issue, stop and start the Microsoft Exchange Address Book (MSExchangeAB) service using the following command from console
net stop msexchangeab
net start msexchangeab
If the service fails to stop and is in the stopping state, open Task Manager. Locate the Microsoft.Exchange.AddressBook.Service.Exe service, right click and end process.
The service will start automatically and resolve the issue.
