Teams mobile app can not switch to new O365 tenant

Hi. 

 

We just migrated our O365 tenant to a newly created tenant, but email addresses are the same as before. Migration is executed and working properly on Desktop. Now we would like to login to the new tenant with mobile app also. We can do this manually, but if we log out and log in again, we always end up on our old environment. How can we achieve that if we just simply open Teams. we login automatically to the new tenant. 
Thanks and regards,
Tamás

    Hi TamasOrtmann,

    Yes, for sure this is what this line in the previous post suggested

    (ideally with new passwords distinguishing it from the exact credentials of the old account)

    The same thing used to happen with Exchange migrations. Organisations typically set up new office 365 accounts in new tenants with exactly the same credentials as in the old tenant so with a combinations of new passwords in the new, and resetting the old you aren't going to have issues with the cache

    Thanks for confirming. Glad it helped!

    Best, Chris

    Hi TamasOrtmann,

    What about after log out, perform a wipe of the Teams App, re-install from the app store and then enter the credentials of the new environment (ideally with new passwords distinguishing it from the exact credentials of the old account)? The device may have cached details of the previous environment and a wipe and reinstall should remove this.

    Let me know how it goes

    Best, Chris

      Hi ChrisHoardMVP 

       

      Thank you for the quick reply. It seems it is cashed and a wipe and reinstall does not solve the issue. I also changed the password, but it is still able to login to the old tenant. 

       

      Regards,

      Tamás

        It may be propagation time of the migration has just been performed. I would say monitor it for a day or two.

        Just to check

        - You have removed everything from the old tenant now the migration is complete including users, domains and licences
        - What is the behaviour when you log out and log in outside the corporate network, the same or different?

        Look forward to hearing from you

        Best, Chris
