With the Marketo / Dynamics integration, there's the handy "Microsoft is Deleted" boolean to, my team thought, indicate whether or not a Marketo lead has had its corresponding Dynamics contact record deleted.
But in reality, "Microsoft is Deleted" is set to true simply by deactivating a Contact in Dynamics. We're looking to remove Leads from Marketo that have truly (for reals) been deleted from Dynamics.
How can we go about verifying the Dynamics Contact has been deleted aside from using the ill named (or ill functioning) "Microsoft is Deleted" flag?
