I understand that Gurango used to have a software that connected the two. It
was called CRM2OA. They have - as far as I can see - discontinued it. With
the discontinuation of this software, is possible that Microsoft (the
developer of both CRM AND OA) has created a linking-tool that will work in a
similar way as the CRM2OA???

We have CRM 3.0 running here, and we have Office Accounting 2007 running
here. We would like to integrate them both so whether you are in one or the
other, either one is updated with whatever invoice, client, payments or
whatever is being entered.
