outlook crush

hello

pc1
win 8.1 office 2013 32bit gpg4win 2.3.4
pc2
win 8.1 office 2013 32bit gpg4win 3

when sending encrypted email from pc2 to pc1 all works fine (dont see the —BEGIN PGP MESSAGE— in email body) .

when sending encrypted email from pc1 to pc2 the message is sent as inline (—BEGIN PGP MESSAGE— Version: GnuPG v2) and there is no option to decrypt on pc2, GpgOl show the insecure icon.

on pc1 i change to simplified interface and restarted outlook
when sending encrypted email from pc1 to pc2 outlook crush sometimes the message does sent, if it was sent pc2 can decrypt the message.

Hi David,

In older Versions of Gpg4win (pre 3.0) proper OpenPGP/MIME Mails are not supported, only the less secure “NO-MIME” Version (sometimes referred as PGP/INLINE). You really should Upgrade PC1 to Gpg4win 3.
I still don’t understand, why you see the first line. I can only imagine, that you have some kind of Anti-Virus programm that attaches something to the mail that makes the former normal “text” mail in NO-MIME Format to an HTML-Mail, and it could be that this can’t be handled. And that may also the reason why Outlook crashes sometimes.

Kind Regards,
Jochen
