How to list all the MS forms which is created for a particular tenant?

Hi Avian 1,

Not currently possible. However, there are multiple uservoices open for this including

See all forms

Powershell

Would recommend you vote to push them up the agenda. To note, Forms is still a relatively young app - its not even in Service Health! - but it is being actively developed so hopefully we will see all this functionality in the future.

I have voted personally on all three.

Best, Chris
