SYMPTOMS
When opening a folder on the Outlook Today page you receive the following error message:

Internet Explorer cannot open the Internet site Outlook:\\/Calendar. The specified protocol is unknown.

In the above example,  is the name of your personal folder which includes the single slash character (/).



CAUSE
The single slash character is interpreted as a folder separator when used in folder names. This is also true for the backslash character (\).



RESOLUTION
Rename the folder using a different name separator, such as the underscore character (_).



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.



MORE INFORMATION
The Outlook Today page is created with HTML. The characters, / or \ when used in a folder name are interpreted as a folder separator by the HTML parser. If you include these characters in the folder name you will receive the error message. To rename the folder use the following steps:


 * 1) On the Folder List, right-click Outlook Today.
 * 2) Click Advanced.
 * 3) On the General tab, type the name of the folder and change the / character to an underscore _. Click OK and OK.

NOTE: The following list of characters may be used in folder names.

NOTE: The following is from an unconfirmed customer report.

You may also be able to workaround this issue by clearing the URL paths located in the following registry key:

HKCU\Software\Microsoft\Office\9.0\Outlook\Today\Folders

The only reference needed is the folder name, not the complete URL.
