You may have noticed that when setting up a new 365 group it will send out a welcome email to every member you add, sometimes this is nice but what if you want to prevent this email from being sent out? Maybe you are still setting up the group or you want to send 1 email to everyone that will be apart of the group to give them a better introduction to the group and it's purpose.

In this post I will walk through the steps to disable this default welcome email.


  • Microsoft Exchange Online PowerShell Module

Installing Microsoft Exchange Online PowerShell Module

Congrats! You should now have the Microsoft Exchange Online PowerShell Module installed 😊

Disabling the welcome email

  2. After signing in and the module has loaded run the below command against the group you want to disable the welcome email for:
