Am wanting to add appointments to an outlook calendar from a web application. Anyone got any ideas on how to go about doing this or any sites / resources I could look at. <BR>I can add appointments to outlook from a windows application but get an access denied error whenever I try from the web application. This error is generated as soon as I try and access the outlook.applicationclass(). I will be using forms authentication on this web application. I have tried giving the user &#039;aspnet&#039; more access rights but it doesn&#039;t seem to make any difference. Any ideas?<BR>Thanks
