I've managed to download and deploy the O365 plugin XML after all.
Now, when I hit the "Encrypt Email" button, the recipient just receives the email in plain.
The encryption does seem to trigger however when using the Subject Line Tagging mechanism in stead.
Anyone else got the O365 plugin working?
