Problem: You apply a Microsoft 365 Business Standard or Premium license in admin.microsoft.com and the End Users Office Install is is complaining that there is no valid license available after opening the Desktop App Versions of Excel, Word, Powerpoint, Outlook etc as the assigned user.

Cause: Desktop apps feature missing or not switched on in assigned license

Checking for missing license feature

To check if Office is missing goto Office.com (sign in as the user) => Apps (left pane) => Install Apps (icon on top right) => "Microsoft 365 Apps" as the user

Check that you have Office in the list of Apps. The "Office" tile will be absent if you don't have a license, or if the correct option is not enabled.
