Teams Sign-in Error Loops

Hello Cristina

Steps to Troubleshoot:

1. Check Enrollment Status:
   • Confirm via the Company Portal app that your device is indeed fully enrolled. Sometimes the enrollment may show as incomplete even if the profile appears installed.
   • Go to the Company Portal and check if there are any pending actions required for the enrollment.
2. App Permissions:
   • Ensure that all necessary permissions are granted for the Teams app. Go to the phone's settings:
   • Settings > Apps > Teams and verify permissions like contacts, storage, microphone, etc. Make sure all required permissions are allowed.
3. Clear Cache for Both Apps:
   • Clear the cache and data for both the Company Portal and Teams apps.
   • Settings > Apps > Company Portal: Clear cache and storage.
   • Settings > Apps > Teams: Clear cache and storage.
4. Check for Profile Issues:
   • Sometimes, removing and re-adding the management profile can help. You may need to:
   1. Go to Settings > General > VPN & Device Management.
   2. Remove the management profile.
   3. Reinstall the Company Portal app.
   4. Re-enroll your device again.
5. Uninstalling the Apps Properly:
   • When uninstalling applications (especially for MDM), ensure you properly remove them from the settings in addition to just deleting the app icons. Go to Settings > Apps and uninstall from there.
6. Device Compatibility:
   • Ensure your device meets the necessary requirements to run Teams and that there are no specific restrictions imposed by your organization’s IT policy.
7. Network Issues:
   • Sometimes, unusual network settings can cause errors with app authentication. Try switching to another Wi-Fi network or using mobile data to see if it changes the behavior.
8. Update Everything:
   • Make sure that all apps (Teams, Company Portal, Authenticator) and your device’s operating system are up to date.

Potential Configuration on IT Side

If the problem persists after your troubleshooting, it's also possible that there may be a misconfiguration on the IT side (e.g., certain device restrictions set up in Intune that affect Teams or mobile device settings).

Conclusion

Resolving issues with device enrollment and Microsoft Teams access often requires a combination of ensuring proper app permissions, removing conflicting data, and checking for IT configurations. By following these steps, you should be able to diagnose and possibly resolve the issue. If the problem continues, your IT department is likely the best resource for resolving more complex MDM-related concerns.
