Error message when starting free Ms teams - 'Someone has already set up Teams for your organisation

harrytowers I am having the same issue. We have never set up Teams for our organisation - I just want to use it at home for my son's remote therapy with his occupational therapist and speech pathologist. 

I had our office IT guy look at it, he can usually solve anything but he couldn't work it out. He put me onto Microsoft support who said I wasn't entitled to help there and had to come here and post. 

If someone invites me to their meeting, it does seem to open up. But I am unable to initiate a meeting.

Zoom was set up in minutes and has worked flawlessly for us however my son's therapy team is hesitant to use it in light of recent media around security issues.
