Unable to login to teams on Samsung fold 7

Dear @Manish Verma 2,

Thank you for sharing the details. I understand how frustrating this is, especially since the issue is affecting your ability to join calls and sign in on Teams.

In this case, to help me narrow this down, could you please confirm the details below:

• Are you using a personal Microsoft account (@outlook.com/hotmail.com) or a work account (@company.com)?
• Are you able to sign in to Microsoft Teams successfully on another device (PC, laptop, or another mobile phone)?
• When you try to sign in, do you see any specific error message or error code?
• Does the issue happen on both Wi‑Fi and mobile data, or only on one network?
• Are you using any VPN, firewall, or security app on the phone?

In the meantime, here are some steps I recommend you try to help me narrow down the issue:
Step 1: Clear Teams app cache and data by going to Settings > Apps > Microsoft Teams > Storage > Tap Clear cache, then Clear data > Select Force stop, reopen Teams, and sign in again.

Step 2: Temporarily disable any VPN > Ensure Teams is allowed to run in the background (Battery optimization off) > Allow both Wi‑Fi and mobile data usage for Teams

Step 3: Try signing in on another phone and on a different network (Wi‑Fi vs mobile data)

Step 4: Please also check how much free storage space is currently available on your phone? Please ensure there is at least 2–3 GB of free internal storage.

If storage is low, please try deleting unused apps or files, clearing cached data (especially media and downloads), restarting the phone after freeing up space, then test Teams again

I hope the information shared helps point you in the right direction. Please try the steps above and let me know if they work. If not, we can continue working together to narrow this down.

The first response may not always resolve the issue right away, but with your help and more details, we can work toward a solution.

Thank you for your patience and understanding. I'm looking forward for your reply.

Follow these steps in order on the Samsung Fold 7 to fix Teams sign-in and connection issues:

1. Verify basic connectivity
   • Confirm other apps can use the internet on the same network.
   • If using a VPN, temporarily turn it off and try Teams again.
   • Restart the Wi‑Fi router/modem and the phone, then retry.
2. Try the Teams web app
   • From the phone’s browser, go to the Teams web version: https://teams.microsoft.com/ and sign in.
   • If the web version works but the app does not, the issue is likely with the mobile app or its cache.
3. Clear Teams app cache (before reinstalling again)
   • On the Samsung Fold 7, go to Settings → Apps → Microsoft Teams.
   • Tap Storage.
   • Tap Clear cache (and optionally Clear data – note this signs out and resets the app, but does not delete Teams data in the cloud).
   • Force stop the app, then reopen and sign in.
   • This step aligns with the scenario where clearing the cache resolved a similar “app hangs when joining meetings” issue.
4. Reinstall Teams cleanly
   • Uninstall Microsoft Teams from the phone.
   • Restart the phone.
   • Install Teams again from the official app store.
   • Open Teams and sign in.
5. Check for sign-in specific issues
   • If an error/status code appears on sign-in, capture it and share it with the organization’s IT admin. Many sign-in problems require admin-side fixes.
   • If the organization uses Conditional Access, MFA, or device compliance policies, ensure the device meets all requirements or contact the IT admin to verify policies.
6. Test on another device/network
   • Sign in to Teams on another device (PC, tablet, or another phone) and/or a different network.
   • If sign-in fails everywhere, the issue may be with the account or tenant; contact the IT admin or Microsoft 365 support.

If, after cache clear + clean reinstall + network checks, Teams still cannot log in on the Fold 7 while other devices work, provide the IT admin with:

• The exact error message or code (if any) on the Teams sign-in screen.
• The date/time of the failed attempts.
• Confirmation that other apps and the Teams web app work on the same device/network.
