Oh and it is commonplace for Microsoft Outlook to be broken in its 
handling of email messages that were send by someone who does not use 
Microsoft Outlook.  I do not use Microsoft Outlook.

I have always assumed that this broken handling is Microsoft's way of 
being passive-aggressive about trying to force users of non-Microsoft 
software to give up and pay money to Microsoft to use Microsoft software.

A further challenge is that many people who receive email are receiving 
the email through a system operated by their employer, and the 
employer's system includes anti-spam and anti-virus functions.  And the 
anti-spam and anti-virus functions are broken in the way that they 
handle emails that are cryptographically signed.

Anybody who has trouble reading an email from me (due to its being 
cryptographically signed) ought to contact their IT department and ask 
their IT department to fix their broken software.
