We're eager to see the new Outlook for Mac client adopt S/MIME support!

Encrypted e-mails generates an AADSTS90072 error on the recieving Outlook. Old Outlook for Mac did not.

When trying to read an encrypted mail I only see the smime.p7m attachmend, not the content. double clicking that brings up keychain with the error "unable to import an item. The content on this item cannot be retrived."
Switching back to old design, everything works well again.
