Disabling ActiveSync for a Group of Users using Powershell

I have tested this only in a Hybrid environment.

  • Create a Universal AD Security Group called O365_Disabled_ActiveSync_Users.
  • Add all the members to it.
  • Make sure it has an email address that registers in Office365.

Connect to Office365 via Powershell ISE:

Copy the following code in a file called DisableActiveSync.ps1 and run in powershell. Add the users in the group will have ActiveSync now disabled.
