When attempting to log in to Microsoft Teams, I am directed to an old organisation for which I no longer have an account, and so I am unable to login.
There appears to be no way to use an alternative login.

@planetmarshall Sounds as if you could have that account in your computer "Account settings". Go have a look there. If not, try this.
For work/school account go here to see if you have an org. to leave https://myaccount.microsoft.com/organizationsAdding for personal account as well, go here https://myapps.microsoft.com/ (the link "Manage my organizations" will take you to the above site too).Note: Use InPrivate / Incognito sessions to avoid cached credentials.
This is great script to clear all settings related to autostart in Teams, simply copy and paste into PowerShell and hit enter.
