[2005] MAPI error

Alright. I have a MS Access database, linked to an Exchange Server. I'm using realtime data. I bind the db to a grid, but when I test in a browser, I get the following error:

Server Error in '/New CSM' Application.

Outlook is installed. What do I do?

Thanks

Is Outlook open on the machine on which this code executes? Are you running under ASP.NET impersonation?

Yes, Outlook is running, but I'm not sure what the impersonation is....

Try closing outlook.

ASP.NET impersonation is when you use Windows Authentication and then have the ASP.NET worker process, as a result, run under the security context of the user running the web application.
