0xCAA30194 error


Have anyone experienced this error after installation while signing into M365 or Teams?  A small set of our companies devices receive this.  We are running M365 Apps for Enterprise E3...or installing MS Teams standalone on a small set of devices.

Yes, I also encountered this problem. I don't know how to solve it.

Another solution is to enable TLS 1.0 / 1.1 and 1.2 in Internet Options. Many users confirmed this quick method worked for them so do give it a try.
It seems you need to enable these settings for Microsoft Teams to work properly. Here’s how to enable TLS 1.0 / 1.1 and 1.2:

Go to Start and type Internet Options
Double-click on the first result
Go to the Advanced tab
