There is only one "mode" for Outlook 2007 that supports full MAPI and
Corporate connections.

What is the Service you are trying to use? I would think the error is with
that service. How old is it?

I am trying to install a UM service that works with Outlook 2007 and it is
giving an error message that says I need to switch to the
coporate/workgroup
option. Can someone please tell me how to do this in Outlook 2007, all the
searches I did only come back with versions prior.

Thanks
