THis teams business and the different versions is really confusing. i hadn't realised there are 2 different versions one for teams.live.com and a different one for teams,microsoft.com
I have a Live account (which I used to use for Outlook.com - as against outlook in Office.
I have an office.com account used for office 365 (or whatever it is called now - the name changes are so confusing)
I have a miccroft.com account for Windows.
I think it is the live.com account that is giving problems.
However as you can see the whole Microsoft system is a total mess.
I think teams is getting totally confused by me logging in microsoft.com. However logging in teams.live.com is impossible with this constant problem of going though the log in and at the end it refuses to accept a perfectly valid code that has been input from the e-mail with the code.
Confused? I think you might be able to see why in the world this whole system if an absolutely confused mess.
Then having these 2 different versions of teams adds to the confusion!
To be honest I have wasted so much time on teams trying to get some sense out of it. The rare times when it has actually worked its feature set in the free version is so limited I have come to the conclusion its just not worth wasting any more time on it but to go back to Zoom or explore something like Slack. The publicity gives the impression of a full feature wonderful happy service but sadly my experience is entirely the opposite.
What I REALLY need is an end to this confusion of having different logins for live, office & Windows. For EVERYTHING to work with just ONE login and password. Until that happens I dont think its worth perusing using TEams. Most people I have spoken to detest it citing similar problems to what I have.
