How to Fix Teams Manifest Error: No Static Tabs Are Configured
Question details
The user is attempting to resolve an issue where a custom Microsoft Teams application displays a static-tab configuration error when accessed via Office.com or Microsoft 365.
- Product
- Microsoft Teams / Microsoft 365
- Device & OS
- not provided
- Scenario
- Running and testing a custom Teams app with a personal tab extension across the broader Microsoft 365 ecosystem.
- Observed behavior
- The custom application works correctly within Microsoft Teams, but fails and throws a 'No static tabs are configured' error when loaded in Office.com or Microsoft 365.
Ensure you have access to the app's manifest.json file and your Microsoft 365 developer account credentials before making changes.
Sign Out and Reload Your Personal Tab
Temporary session caching issues can prevent Office.com from properly reading the Teams app manifest. Re-authenticating forces the system to pull the latest configuration.
Often, Microsoft 365 portals cache older versions of an application's state. When developing personal tabs, simply signing out and clearing this session data can quickly resolve false error flags.
Navigate to Office.com, click your profile picture in the top right corner, and select 'Sign out' from the dropdown menu.
Press Ctrl + Shift + Delete (Windows) or Cmd + Shift + Backspace (Mac) to clear your recent browser cache, or open a new Private/Incognito browsing window.
Return to Office.com and sign in again with your Microsoft 365 developer account credentials.
Open your custom Teams application within the Microsoft 365 portal and reload the personal tab to check if the error is resolved.
Verify Static Tab Support in Your Manifest File
Not all manifest configurations valid for Teams are supported by Office.com. Checking your manifest structure ensures cross-app compatibility.
Consult the Microsoft Teams Development Community
If you are still unable to resolve the static tab error, submitting your manifest code to official Microsoft support channels is the best next step.

Frequently Asked Questions
What is a static tab in a Microsoft Teams manifest?
A static tab (also known as a personal tab) in Microsoft Teams is a dedicated workspace within an app that provides a user with a personalized, full-screen view of content, defined in the app's manifest.json file under the 'staticTabs' array.
Why does my custom Teams app work in the desktop client but fail in Office.com?
Office.com and Microsoft 365 environments often require a newer manifest schema (version 1.13 or higher) and have stricter caching rules. An app may work in the Teams client using older schemas, but extending it to Office.com requires strict compliance with the updated static tab configuration requirements.
Where can I find the manifest.json file for my Teams app?
The manifest.json file is located in the root directory of your app's source code package. If you used the Teams Toolkit or Developer Portal, it can also be accessed and edited directly through those interfaces.
Will clearing my browser cache fix the Microsoft 365 static tab error?
Yes, in many cases. Microsoft 365 web applications heavily cache session data. If you recently updated your app's manifest, clearing your cache and signing back in forces the portal to fetch your updated static tab configurations.
