I have a personal microsoft account and a business account. They have always been separate by choosing the profile to use. Through my business account, I am part of a client Teams account as an approved tenant. Every time I try to log in now, it either gets blocked stating my personal account is not an approved tenant, or it goes back to the generic sign-in screen and has no functionality
Changing between multiple Microsoft Teams accounts within the app or browser
Hello
Can you go to your web browser in incognito mode, then go to https://teams.microsoft.com/v2, then sign into your business account, and then switch to the client tenant tethered to your business account, does it let you get in?

Hi Kevin,
Based on your description, it sounds like Microsoft Teams may be attempting to authenticate with your personal Microsoft account instead of your work account, which can result in tenant access errors or repeated sign-in prompts.
As a troubleshooting step, please try the following:
If you have both personal and work accounts signed in within the browser (Edge, Chrome,...) on Teams on the web, sign out of all Microsoft accounts first, clear your browser cache, then sign in only with the business account and test whether you can access the client's Teams tenant.
Additionally, I'd advise you to change your personal account alias to avoid future conflict. For guidance, please consult: Change the email address for your Microsoft account | Microsoft Support
I hope this provides enough clarity and helps you stay inform with your current situation.
