When I open teams, it automatically sets to old user id. How do I change the user id?

    Hello

    Is this old user ID a personal one or a business one?

    Are you using Teams on Windows 11, or macOS? Please provide the information as the instructions can be very different.

    If Teams keeps opening with an old user ID, use the correct account type and then sign out of the old one.

    1. Check whether Teams signed in with a personal Microsoft account instead of a work or school account.
      • Signs this happened include missing work items such as assignments, meeting notes, recordings, or the work/school calendar.
      • In that case, add and sign in with the work or school account from within Teams.
    2. If the computer is domain-joined, Teams can automatically use the domain-joined Windows profile.
      • To switch accounts, sign out of Teams and manually sign in with the other account.
      • If Teams is restarted after sign-out, it can automatically sign back in with the domain-joined account again.
    3. If the old user name is being prefilled on a domain-joined PC, an admin can turn off that prefill by setting this Windows registry value:
      • Computer\HKEY_CURRENT_USER\Software\Microsoft\Office\Teams
      • SkipUpnPrefill = REG_DWORD
      • Value: 0x00000001 (1)
      • Warning: registry changes can affect sign-in behavior. This should be done carefully, preferably by IT.
    4. If the old account is no longer valid on Windows, remove the old work account from Windows:
      • Go to Settings > Accounts > Access work or school.
      • If the old organization account is listed, select it and disconnect it.

    A Teams user ID for work or school is typically the work or school email address used to sign in, such as an account assigned by the organization.
