Tracking associated users, rooms, services by physical business location.

Please redirect me and/or the message if this would be best posted elsewhere:

We have several hundred users whose user data has not been kept up (no address location, phone numbers, etc.). Because we are still in hybrid mode the users cannot update their own data. Still, it seems I should be able to populate user addresses from a location lookup (we have 52). 

Also, each of those business locations has services and other data that I want to be able to look up and share in a smarter way than a spreadsheet. 

Can somebody buy me a clue?  

Thanks
