How can I update an encryption security in Outlook contacts?
I got an email signed with an updated certificate by someone who is already in my contacts with an expired certificate.
If I REPLY to that email, I can encrypt my reply and it works. However, if I try to make a new email to the same contact it does not work.
If I right-click on the From: field of the new email from the contact, and choose Add to Contacts, in other words try to create a brand new contact record (with the new certificate), it does not create a new Contact, it just brings up the old contact record with the old, expired certificate in it.

The option to update the contact with the new certificate no longer exists in the newest Outlook version (2016/365). This was available for 2007/2010/2013.
You must delete the contact containing the old certificate, and then add the contact anew.
