Deploying WebForm

I am writing an event management website for my company and keep hitting my head off a brick wall!

I am using VS2005 (Visual Web Dev & vbscript) to create a page that takes data such as dates,times and ad-hoc requests and creates a wordfile and is sent to the required users as an attachment (using Outlook 2003 exchange server). This is working fine on both my localhost and the server.

Next I want to send a meeting request/calendar entry to the required users. This is working fine on my localhost but when deployed on the server (IIS 6.0) I keep getting the following error
"
System.Exception: Cannot create ActiveX component
.
..
Line 219: objOExp = CreateObject("Outlook.Application")
"

I have allowed permissions on system32 & Office11 folders, the correct .dlls are present but it still persists!
Any help would be appreciated

Did you check the IIS web site permissions? (You can view it on the IIS management console)
