If you need to get a list of Office 365 Group owners in your organization, this guide is for you! This blog post will show you how to use PowerShell to find all group owners in Office 365. Let’s get started!

To get Office 365 group owners from Microsoft 365 admin center, do the following:

Log in to the Microsoft 365 Admin Center site: https://admin.microsoft.com

This opens the group’s details page, which lists group Owners
