I was fiddling around in my Office 365 tenant and saw that the Mobile Device Management now appears as a license for the user as shown above.

I then headed to the Office 365 Admin portal and sure enough on the menu on the left hand side I see Mobile Devices.

When I select this I get some information on the right and a Get Started button which I press eagerly.

Office 365 starts settings things up for me and says it may take a few hours (!). Actually, it took the whole of about 5 minutes.

Now I see the above. I select the Manage settings in the top right.

From the window that appears I select Set up from Configure an APNs Certificate for iOS devices.

At the next screen I select Download your CSR file link and store it on my C: drive.
I then select Next to continue.

Here I select the link for Apple APNS Portal.

I login with a company Apple ID.

Once logged in I select the Create Certificate button.

I Accept the Terms of Use

I now upload the CSR file that I downloaded previously.

I receive confirmation that all is good. I select Download to get a copy of this Apple Certificate and store it on my local hard disk.

I return to the Office 365 Admin portal and upload the Apple Certificate I just downloaded into Office 365.

I now get the message that the Certificate Uploaded Successfully.

In the top right corner of the windows I now have a green check indicating that my Apple Certificate is uploaded and valid.

Select the link Manage device security policies and access rules near the top of the page.
\
I’m now taken to the Office 365 Compliance center and the option Device Management as shown above.

I select the option to create a new policy by selecting the + (plus) icon. I then given the policy a name and select Next.

Now I can select all the device security options I want.
When complete, I press Next to continue.

I now get the option to select more configuration options as shown above.
When complete, I press Next to continue.

I now elect whether I wish the policy to be applied to my users. At stage stage I will leave the option set to No and press Next.

I now get a summary to review and when complete I select finish.

You should now see your policy listed as shown above.
If I now want to apply that policy to a user I select the pencil icon to edit it.

I select the Deployment option on the left and then Yes. I then select the + (plus) icon that appears to add the desired user(s) to whom the policy should apply.

Unfortunately, at this stage I get the above error that doesn’t allow me to apply the mobile device policy to a user for some reason.
I suspect I have stuffed up somewhere so I’ll do some research and post an update soon.
Till then, if you see Mobile Device Management appear in your Office 365 tenant, have a play and let me know how you go.
