Thank you for reaching us!
I understand that you having trouble logging in to your email and Teams with the institutional account.
If you have backed up your credentials to the cloud, you can recover your credentials in the Authenticator app, ensure that no additional accounts have been linked to the newly installed app.
To recover your credentials, open the Authenticator app, and select "Begi recovery". Please sign into your recovery account which you used during the backup process and follow the steps mentioned here.
If the issue is still persisted reach out to your institution's IT support or helpdesk and explain the situation to them, they should be able to assist you in recovering access to your account.
Thanks,
Akhilesh.
