I'm getting the following error:-
This might be because the site uses outdated or unsafe TLS security settings. If this keeps happening, try contacting the website’s owner.
It doesn't matter what browser I am using, Edge, Chrome or IE, been like it all day..
I don't experience any issues. You could check the service health in your Office 365 admin center to see if there's maintenance going on or known outages
I'm currently trialling the free version.
However, the problem seems to have sorted itself out now and the teams site is back and running..
