Loss of access to Microsoft Teams Myfood [INC-TEA-004]

Discovery date : 25/11/2025
Criticality : medium
Impact : limited
Description of the incident :
Difficulties accessing Microsoft Teams Myfood. Cause #1: These errors generally come from using the wrong Microsoft account when signing in. You are not using the same Microsoft account as when you accepted the invitation.

When you were invited to join Teams Myfood, you accepted this invitation with a specific Microsoft account (personal Outlook/Live account, professional Microsoft 365 account or an account linked to your external address).

It is possible for the same email address to exist on several different Microsoft accounts. In this case, Teams cannot find your profile and displays an error such as:

« AADSTS50020 – User account does not exist in tenant Myfood »

This simply means that you are signed in with a different account from the one used when accepting the invitation.

Resolution : Please follow the steps below

  1. Check that you are using the correct Microsoft account
    Sign out of all your Microsoft Teams accounts

    • Your web browser
    • The Teams mobile app

Then sign back in using exactly the email address that received the Myfood invitation. This is the most important step

  1. Force a clean reconnection

    Depending on the device used:

On mobile
• Uninstall/reinstall the app
(If needed, you can clear the Microsoft Teams app cache from your phone settings.)

In a browser
• Open Teams in an Incognito / InPrivate / Private Browsing window (This helps avoid saved Microsoft sessions.)
• Sign in to Teams with the correct account.

  1. If it still does not work, and only as a last resort!

We can reset your invitation and send you a new access link. This operation automatically cancels the previous invitation.
