Reading Outlook Exchange emails in a service

Hi everybody,
I ‘trying to open an emailsession for Outlook Exchange in a service with EmailStartOutlookSession(“Outlook”)
but always get the error message :

Unable to open the session with the 'Outlook' profile
Error code: 520045
Level: non-fatal error
System error code: -2147221246
System error message:
Invalid window handle



The 'Outlook' profile exists and in runtime my code works.
The service is connected to the right user and has administrator rights.
Does anybody has experience with reading outlook mails in a service ?

Hi,

I am not sure, wheather I am correct or not, but:
A Service can not have a Gui and can not interact with a Gui and according to the help a Service can not call locking functions.

So I am quite sure, that EmailStartOutlookSession() is a locking function or tries to interact with the gui.

Your error message Claims an invalid window handle, which indicates that some Gui operations are started.

Regards



Stefan.

Agree with Stefan, however, you could try accessing the folders by way of the Outlook Interop API.
