How to Remove a SharePoint AppSource Add-In from All Sites
Question details
The user needs to completely remove a Microsoft AppSource add-in (PDF-XChange) from their entire SharePoint tenant, as it does not appear in standard Site Contents.

- Product
- Microsoft SharePoint
- Device & OS
- not provided
- Scenario
- Uninstalling a tenant-wide SharePoint add-in that was installed via Microsoft AppSource.
- Observed behavior
- The add-in shows as installed in SharePoint but cannot be found or removed from individual Site Contents, and the installation persists across different computers.
Ensure you have SharePoint administrator or Global administrator permissions, as tenant-level app removal requires elevated administrative access.
Remove the Add-In via the SharePoint Admin Center
Use the SharePoint Admin Center's App Catalog to delete tenant-level add-ins that do not appear in individual Site Contents.
Add-ins installed directly from Microsoft AppSource at the organizational level are managed centrally. Attempting to remove them from individual site settings will not work because the app is deployed to the entire tenant.
Log in to your Microsoft 365 admin account and navigate to the SharePoint admin center.
In the left navigation pane, select 'More features' and then click on 'Open' under the 'Apps' section to access the App Catalog management page.
Find 'PDF-XChange' (or your specific add-in) in the list of installed apps. Select it and click the 'Delete' option.
Check your relevant SharePoint sites to confirm the app has been successfully removed and ensure no app installation remains in the tenant catalog.

Frequently Asked Questions
Why doesn't my AppSource add-in show up in Site Contents?
Add-ins deployed at the tenant level by an administrator often do not appear in individual Site Contents. They must be managed centrally through the Apps section of the SharePoint Admin Center.
Can I remove a SharePoint add-in without administrator permissions?
No, if the add-in was installed tenant-wide via AppSource, you must have SharePoint Administrator or Global Administrator rights to remove it from the centralized App Catalog.
What happens if I delete an app from the SharePoint App Catalog?
Deleting the app removes it from the tenant catalog, successfully uninstalling it and making it unavailable for users and sites across your entire SharePoint environment.
