Why publish your app with Microsoft’s app stores
Your app can be distributed directly through the Microsoft 365 app stores inside of Outlook, Excel, PowerPoint, Teams, and SharePoint, where millions of customers around the world are working everyday.
In addition to the Microsoft 365 app store, Microsoft AppSource is another distribution point for your app. It's the official app store for Microsoft 365 apps and solutions.
When you submit your app for validation and it's approved, your app is automatically added to both the Office and Microsoft AppSource stores.
