Microsoft Teams to Outlook

Hi all,

I am on a 2019 iMac with MS office installed.

In Outlook, MS-Team's is not an option in the calendar (to schedule a Teams meeting etc.) meaning when someone sends me a MS-T invite I cannot connect straight to it from Outlook (like I can in my employers environment).

I have to copy the MS-T invite into the browser & join from there which isn't great (some connection issues).

I have the separate MS-Teams app installed, when I log into that all it says is 'start a new call' etc. my diary invites are not in there.

Help please!
