How to re-create virtual directories in Exchange 2010

[guest]

If you remove a virtual directory using the EMS, you cannot create the new one using the EMC. Virtual directories can only be re-created in the EMC.

With Exchange Server 2010 SP1, you can re-create virtual directories via the Exchange Management Console (EMC). To create re-create virtual directories, open EMC.
In the Server Configuration node, click Client Access in the right-hand action pane. From there, you have the option to reset virtual directories. You then use the wizard to re-create the required virtual directory.
