Fix Missing Third-Party Add-Ins in Microsoft 365 for the Web
Question details
The user needs to restore access to third-party add-ins in the desktop browser version of Microsoft 365.
- Product
- Microsoft 365 for the Web
- Device & OS
- not provided
- Scenario
- Using Microsoft 365 in a desktop web browser after a GoDaddy migration.
- Observed behavior
- Third-party add-ins are successfully visible in the mobile app but have unexpectedly disappeared from the desktop browser experience.
Ensure you have the contact information for your Microsoft 365 tenant administrator, as resolving add-in visibility issues often requires administrative access to the Microsoft 365 admin center.
Verify Add-in Permissions in the Microsoft 365 Admin Center
Use this solution to ensure that marketplace or integrated-app restrictions are not blocking the add-ins in the web environment.
Following a migration (such as through GoDaddy), organizational policies and app permissions can occasionally become desynchronized between mobile and web environments.
Only a tenant administrator can modify these configurations. If you are not the administrator, you will need to request that they perform these steps.
Have the tenant administrator navigate to the Microsoft 365 admin center and log in with their administrator credentials.
In the left-hand navigation menu, click on 'Settings' and then select 'Integrated apps'.
Review the list of deployed apps and ensure that third-party add-ins are set to 'Available' for the affected users. Verify that there are no tenant-wide blocks on the Office Store.
If any permissions were restricted, update them to allow access, save the changes, and wait for the new policies to propagate to the web client.
Clear Browser Cache and Wait for Auto-Resolution
Sometimes, temporary caching issues during a migration cause add-ins to hide, and the system resolves itself after a refresh.
Avoid Complex Migration Issues with WPS Office
If strict tenant permissions, complex admin centers, and migration issues in Microsoft 365 are disrupting your workflow, consider using WPS Office. It provides a straightforward, highly compatible office suite without the hassle of backend web-configuration problems.
- 1. Download WPS Office: Visit the official WPS Office website and download the free installation package for your operating system.
- 2. Install the Software: Run the installer and follow the simple on-screen instructions to set up the suite on your computer.
- 3. Open Your Documents: Right-click your existing Microsoft Office files and select 'Open with WPS Office' to continue working seamlessly.
Frequently Asked Questions
Why do Microsoft 365 add-ins work on mobile apps but not on the web browser?
Mobile apps and web browsers retrieve configuration policies differently. After a migration, mobile apps might retain cached access tokens, while the web version strictly queries the latest tenant policies, which may temporarily block add-ins due to marketplace restrictions.
How long does it take for add-ins to reappear after changing permissions in the Admin Center?
Once a tenant administrator updates integrated app settings or removes marketplace restrictions in the Microsoft 365 Admin Center, it typically takes between 12 to 24 hours for the changes to fully propagate to all users' web browsers.
Can an IT administrator block me from using third-party add-ins?
Yes. Microsoft 365 tenant administrators have the authority to block the installation or execution of third-party add-ins for security and compliance reasons via the Integrated Apps settings in the Admin Center.
Do I need admin rights to restore the add-ins?
If the add-ins disappeared due to an organizational policy change or a migration setup issue, you cannot fix it locally. You must contact your IT administrator to adjust the tenant-level permissions.
