Goal: I would like to see all of the ActiveSync device serial numbers (or IMEI's) within my Exchange environment.
Back Story: I was given a serial number of "12345" by a colleague and I need to determine who is using that phone within our organization. So I was thinking of compiling a list of all serial numbers and finding it within the list.
The only thing that I just realized is that Exchange does not log iOS device's IMEI numbers, unfortunately.
You wouldn't happen to know any way around that, would you?
