Right now I have a corporate office 365 setup with about 2000 users. I need to be able to authenticate locally now with these users. My understanding is that the only way I can do this is use azure connect to sync the users locally and then sync them back up and match them up to office 365. First of all is this correct?
Second... If I only want to sync a subset of the 2000 users (around 400 or so) what happens to the other 1600? Can azure connect be set up to ignore the mismatch and just leave the other accounts on office 365 without touching them?
