Hello,
One of my users has been getting this error code - 80080300 whenever they try to login to Teams with their work email. Tried clearing cache, reinstalling latest version, PC reboot, cleaning registry. Logging into the account through Teams online through Chrome works fine, but the app itself won't launch. Anyone have any issues like this?
Thanks for your assistance.

@Aryan_Raje This worked and was super helpful to fix an annoying issue that uninstalling / reinstalling didn't fix. Thanks.

Setting the compatability mode to windows 8 worked for me too. Think without this Teams doesn't let you login with details (login password) that are different to the machine you are logged in on. Annoying when using a work teams account from a home PC. Logging in to teams and adding a work account gave the error you describe. The work around presents a new login screen allowing you to enter both a different email and password to the machine you are logged into. Hope microsoft rectify this.

I'm having the same issue, the same error. If I run Teams as admin, it shows me a screen telling that will send me an e-mail to "myuser@mydomain", there is no way to receive this e-mail. I can only use Teams via Web.. also, tried installing the latest version but it doesn't work too.
Edt: Tried the steps that Aryan_Raje told but I get the same screen that I told above, telling that Microsoft wil send me an e-mail..

I just solved it uninstalling the last two Windows updates.

Thanks @Aryan_Raje the Windows 8 compatibility worked for me too!
@hobbesboss browse to: C:\Users\<username>\AppData\Local\Microsoft\Teams and find Update.exe right click, choose properties > compatibility and choose Windows 8 in the drop down.
Then use the shortcut on your desktop or Teams menu to start Teams
