I have exchange 2019 which i use as a hosted server with multiple businesses connected to it as tennents. I list their own domain as an excepted domain on the server. How do i migrate them to their own o365 email? is there an easy migration ? I am happy to create each business their own 365 account and assign licenses. We would only be doing about 40-50 users between 3 to 4 buinesses. Would like to know the following. 1. Can you integrate AD so users are created in 365 automatically? or do i need to create them? 2. most importantly, can malboxes be migrated automatically. this is what i mostly need. Would want to do 1 buisness each week until complete. Please provide your info, no just generic application. on what your process will be and what steps I need to do in order to help you. Looking to start in a couple of weeks.
