Accessing Free/Busy Exchange Data Using ASP

[rnaimon]

I found the following information on this site, but I am unable to get it to work. All it brings back is the xml page with no data. I am running a Windows 2003 Server with Exchange 2003 Server.

When the code gets to This line..

If objDoc.loadXml(objRequest.ResponseText) Then

The results return False and I don't receive any data. Does anyone know what the problem may be?

Re: ASP: Exchange 2003 Free/Busy Lookup
--------------------------------------------------------------------------------

I have figured this out myself. The problem was with Anonymous access being
disabled within the IIS for the public folder. Once I enabled this I was
able to retrieve an XML file of the specified users free/busy status.

Also the code I was using was for exchange2000 and not 2003, this brought
back a HTML formatted page of the specified users free/busy status. Once I
used the 2003 code this brought back an XML file.

I hope this helps someone else out.
