Active Directory - Add or remove multiple members from a security Group

Question

What's the maximum limit to add/remove users to a security group in On-Prem AD? Also, is there a limit to the sync process between On-Prem & AZURE Sync for such additions?

e.g. can I add 100K users to an AD Group using PowerShell script in a single run?

Answer 1

In theory yes, however note some caveats:
