Unable to expand Public Folders in Outlook on Exchange 2010
Posted by Alan McBurney on June 27, 2011
Outlook clients were unable to expand public folders with the following error being displayd
Public folders access using OWA was fine.
After looking at the Mailbox server the RPC Client Access service was stopped
The service wouldn’t come online complaining that the port was already in use.
A reboot of the server resolved the issue
