A lot of people, including myself have looked for an easy way to search for users by license type. Maybe you are in the middle of a migration and had trial accounts, but now it is time to move them to paid licenses. In the new Wave 15 environment there is an easy way to do this, follow the steps below.
Office 365 – Search by License
Login to the Office 365 Admin center. Click on the filter icon.
In the drop down, click “New View.”
On the next screen, pick a name for you view.
Then if you scroll down you can choose the “assigned license” in the dropdown. In my example I am choosing “Microsoft Office 365 Plan E3″ because they were trial licenses used in the migration and I want to see who all is left on those licenses that I need to move.
Then simply click your view in the dropdown on the search page and it will display the users just with your trial licenses.
You can login to your 365 Admin portal here.
