To sign-in to our Apps and Add-ins, you will need either an organizational Microsoft 365 account or a personal Microsoft account.Microsoft 365 subscriptionsWe do not offer a list of supported Microsoft 365 subscriptions you need to have to run our Apps and Add-ins. We can say, though, that to get the most out of our applications, you would need either Microsoft Teams or Microsoft SharePoint online to connect to your files and data repositories. Other than that, you should also check if Microsoft 365 Centralized Deployment is supported in your subscription as this will make it super easy and fast to deploy our apps t your users. A mixture of Microsoft 365 subscription types should be no problem as long as you share the same Microsoft 365 tenant.
