Encrypt options greyed out in Outlook desktop

I have Office 365 Business Premium with Outlook for Office 365 MSO (16.0.12130.20382) 64-bit desktop. This plan does not support Office 365 Message Encryption (OME) on it's own but I added Azure Information Protection Premium P1.

 

With this set up I'm able to use the encrypt options with Outlook Web.

 

In Outlook desktop, the Encrypt button is available but the OME options are greyed out

 

Should these OME options be accessible in Outlook desktop with this setup?

 

In addition, I sent a test "Do Not Forward" encrypted message from Outlook Web to another one of my O365 email addresses in a different domain. This is supposed to keep the recipient from copying, printing or forwarding the message. However I was able to do all three actions after receiving the message. Here's the sent message showing that it was set to Do Not Forward and the received message showing that it was forwarded after receipt:

 

Any idea what's going on there?
