as usual, thanks for your help.

I'm having a very similar problem in 3.1.5! Randomly, when I try to view a PGP-signed e-mail, nothing shows, both on preview panel and when I open the message.

File->Save As now works for crypto mails. It saves the encrypted message.
This works now, the hidden BeforePrint Event enabled us to detect when a print happens and the old code to do blocking decrypts enabled the actual printing.
We also do not print "our categories" (encrypted message, level x trust),... anymore, even in quick print.

The change in message class did not help.
Works for me

My understanding of this issue and the fix for it is that Outlook with exchange detects that our mails are S/MIME mails. As the attachments are modified by us outlook wants to save the changes on move. This fails because it can't do the crypto. Leading to the error. This also happens when such a mail is closed.
We did not remove the "<>" from the content id. This worked for the first display but when forwarding they got doubled and it broke.
The code had the assumption that a content-id
could only exist on an attachment for HTML mails as it otherwise
does not make sense.

I was able to reproduce this when I forwarded the mail after opening it in a new window. Somehow that appears to influence it.
