Exchange Virtual Directory Cannot Be IIS Home Directory

ID: Q189653


The information in this article applies to:
  • Microsoft Exchange Active Server Components, version 5.0
  • Microsoft Outlook Web Access, version 5.5


SYMPTOMS

When you use Microsoft Internet Information Server (IIS) version 3.0 with Microsoft Exchange Server version 5.0 or 5.5, and you are trying to open the Exchange Server 5.0 Active Server Pages or the Exchange Server 5.5 Outlook Web Access (OWA) pages, you may see the following errors message when using Microsoft Internet Explorer version 3.02:

HTTP/1.0 403 access forbidden
And the following error message when using Microsoft Internet Explorer version 4.0:
HTTP/1.0 invalid application name
Using IIS 4.0 with Exchange Server 5.5 and trying to open up the OWA pages may produce the following error message:
Directory Listing Denied. The virtual directory does not allow contents
to be listed.


CAUSE

These errors will occur when the Exchange Server Virtual Directory is set to be the IIS home directory.

The Exchange Active Server Components for Exchange Server 5.0 or the Outlook Web Access components for Exchange Server 5.5 are coded to use the /Exchange alias


WORKAROUND

To work around this problem:

  • Do not use the Exchange Virtual Directory as an IIS home directory.


  • The Exchange Virtual Directory can be used as a virtual server.


  • Create a Default.htm file in the root of the IIS server to jump directly into the Exchange Virtual Directory. See sample below.
