Please kindly understand under Outlook tag, we mainly focus on general issues about Outlook desktop client, I noticed that your issue may be more related to the encryption configuration in Exchange, in order to solve it better, I added relevant exchange tag under your post, thanks for your understanding.

S/MIME for message signing and encryptionIf you would like to only allow some of the users sending encrypted messages, as Chris suggested, their AD account should have the user certificate published in the attributes UserSMIMECertificate and/or UserCertificate.
