UNABLE TO ACCES TEAMS WITH THE ADDITIONAL APP

Hello @PETER WANYAMA,

Thank you for reaching out.

To better understand the issue you’re experiencing with accessing Microsoft Teams as an additional app, could you please help clarify a few details for me?

When you say you’re unable to access Teams, is there a specific error message displayed, or does the app simply fail to open or load? If possible, could you please share a screenshot of what you see when the issue occurs? This will help me identify the exact point where the problem happens.

Additionally, I’d like to ask a few more questions to narrow this down:

• Could you please confirm whether you’re using a work or school account issued by your organization or school, or a personal account (for example: hotmail.com, outlook.com, or gmail.com)?
• Are you trying to access Teams through the desktop app, web browser, or mobile app?
• Has Teams worked for you before with the same account, or is this the first time you’re trying to access it?

With this information, I’ll be in a better position to guide you toward the appropriate next steps. Please understand that our initial response does not always resolve the issue immediately. However, with your help and more detailed information, we can work together to find a solution. 

Thank you in advance for your help, and I look forward to your reply.

Kind regards,

Try these steps in order to regain access to Microsoft Teams using the additional (desktop) app:

1. Restore access by signing in again
   • Open the Teams app and look for a Sign in banner or button at the top.
   • Select Sign in and complete your credentials and any multi-factor authentication (MFA) prompts.
   • If no button is visible, check the notification area near the clock on the taskbar for a Teams icon with a dot or exclamation mark, then select it to open the sign-in window.
   • If the sign-in window still does not appear, right-click the Teams icon in the notification area, select Quit, then reopen Teams and sign in again.
2. Check network and VPN requirements
   • Connect to the network your organization requires before opening Teams (for example, connect to VPN first if required).
   • Avoid switching between networks (e.g., office Wi‑Fi to public Wi‑Fi) while Teams is open; if a switch is needed, sign out of Teams first, then sign back in after reconnecting.
3. If Teams still will not reconnect
   • Uninstall the Teams app from your device and then reinstall it.
   • If using a VPN to access Teams, turn the VPN off and back on, then try again.
   • If the desktop app continues to fail, try using the web version at https://teams.microsoft.com/.
4. If sign-in errors continue
   • When a sign-in error appears, note the status code shown in the lower-left corner of the Teams window.
   • Provide this status code to the organization’s IT administrator, as many sign-in issues can only be resolved by an admin.
5. Keep Teams updated
   • In Teams, select the profile picture and choose Check for updates (if available) to ensure the latest version is installed.

If the banner or sign-in prompts keep reappearing after these steps, contact the organization’s IT administrator with details of the error and any status code shown.
