    OMG…thank you for this tutorial, you saved me lots of strife today! I wish I never installed Azure AD, it used the domain name for email addresses and would not allow me to remove the affected users making it a nightmare to know which account to fix, plus it imported users that were terminated years ago up until now…that is hundreds of people!
    Thank you, thank you, thank you!!!

    Very helpful info. My latest two incidents were:
    1. Premier Plan2 production AAD with 50K objects, took 13 hours to fully disabled. Took another 2 hours full re-sync after re-enabled.
    2. Test AAD with 200 objects in Plan1, took 20 hours. Cheap plan took longer.

    Thanks all.
