In this article, I'll explain how to assign or remove Office 365 user licences in bulk based on their group membership, without using PowerShell scripts.

Steps:

• Log in to O365 Manager Plus with admin credentials.
  
• Go to the Management tab.
  
• Navigate to License drop-down > Bulk Group Modification > Group Based License Modification.
  

• In the window that opens up, click the Assign/ remove licenses drop-down and select an option based on your requirement. You can either choose to Assign selected licenses, Remove selected licenses, Modify selected licenses, or Remove all licenses.
  
• Select Licenses from the drop-down and configure the Usage location.
  
• Select Groups from the displayed list to filter users based on their group membership.  
  
• Select the Office 365 Tenant and Virtual Tenant to which you want to apply the selected settings.
  
• To select the required users manually, enter their names in the search box.
  
• Click Apply to execute.
  

That's it! You now know how to easily manage user licenses in bulk, using O365 Manager Plus.
