So here's what I would like to do. Get a list of ActiveSync users from the server, which is actually pretty easy with: GetActiveSyncUsers. After this, I would like to find out what devices are used and preferably the last sync date. It seems possible since it's listed under each user for Synchronized Devices, but I can't seem to find anything in the API calls. My guess would be under /Services/svcUserAdmin.asmx as GetActiveSyncUsers is there. Am I missing something?
My end goal is basically to do a quick audit of the users, and disable anyone that hasn't used ActiveSync for some extended period of time, as I have a feeling that most domain admins are just adding the feature for no reason.
