You can use the Shell to remove a Microsoft Office Outlook Web App virtual directory.

Don't use Internet Information Services (IIS) Manager to remove an Outlook Web App virtual directory. Using IIS Manager to do this may result in what's known as an "orphan" virtual directory. Instead, use the procedure in this topic. You can use the same procedure to remove orphan virtual directories.

If the last Outlook Web App virtual directory to be removed was an orphan virtual directory, you must manually remove the Outlook Web App ISAPI filter from the associated Web site. See the procedures in this topic for how to find orphan virtual directories, and manually remove them.
