Office365: I can't see MDM management in my subscription yet. Trial E3 subscription most affected.

I was able to switch on management of Office365 MDM functionality in my production environment - mobile option was in place, but in the trial subscription, where I wanted to check the things out before deploying in production - option was not visible.

How to turn on Office365 MDM in my subscription?
In Office365 administration panel there is an option regarding updates.
Because Microsoft now rolls out this feature is not deployed everywhere.
If you want to see this option on your side, you need to change update settings from "Standard Release" to "First Release"

In the user' license tab you can find that MDM option is not active yet

And in the Office365 option you cannot find 'Mobile' section

Youi should go to "Updates" section

And change it from "Standard Release" to "First Release"

And after a while you should see 'Mobile Devices" section
