Hi all,

I have a workflow application, where i have usded Outlook interop to send an appointment invitation to the users.

Please see the following code. Now the problem is that when ever i am running the same code to test in a console application i am able to send the emai, but as soon as when i put this code to a my workflow activity, this code fails with the following error:

"An unhandled win32 exception occured in outlook.exe[4628]"

and when i debug this i get following

"ex = {"Retrieving the COM class factory for component with CLSID {0006F03A-0000-0000-C000-000000000046} failed due to the following error: 80080005."}"

Any help on this is really appreciated.

Following code expalins this

                        //This method save the appointment to the outlook
                        //oAppointment.Save();
 
                        olMailItem = oAppointment.ForwardAsVcal();
