Messages are not encrypting in Outlook 365

[dfiore]

We are finding that in Outlook (Office 365) we install the plugin, verify the encrypt button works and send an encrypted message although the recipient is getting the message completely UNENCRYPTED. Is this a known issue? Is there a different pluging for Office 365 users? We replicated it on multiple systems. Thank you

Can you confirm which mode you are using the plugin in? Flag or desktop encryption.

If it is set to flag encryption we will need to verify the message tracking for the emails to see if they hit the filter configured to encrypt the email.

The plugin is compatible with the email clients listed below so you can verify that:

We have tested using IE11 on Windows 10 and using [ENCRYPT] on an iPhone, but with a user that has an Office 365 account.

One interesting item of note is Outlook 365, which is not the same as 2016, is not listed at all in your compatibility matrix. I searched for only 365.
