[2005] MAPI error

[southernprince]

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?

[southernprince]

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

[mendhak]

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.
