Kevin, did you ever get this to work in Azure? I managed to get MAS_System to work. I can create new users and other things fully contained in System files, but apparently Azure doesn't support cross-database queries so Company Maintenance which is MAS_System checking into MAS_ABX doesn't work. Likewise, MAS_ABX doing anything at all doesn't work due to not being able to read System settings. Microsoft is looking into a workaround for me, but at this point, it seems like this isn't an option.
