Description

When mails are sent via attachment, the attachment is displayed empty in both preview and opened window if

the attached mail is written in text-only format and is signed and/or encrypted
the attached mail has encrypted attachments

I have generated mails with all permutations of outlook formats (html, rich, text) * (un)signed * (un)encrypted and sent them via attachment in various ways. Sending the attachments signed and/or encrypted does not matter, neither if it's a single or multiple attachements. In all cases the empty display in the preview / opened window is the same. This behaviour can be seen e.g. in the following attachments of the mail Ted:INBOX/Anhänge/attached unsigned unencrypted: all mailformats (15:07):

TEXT signed unencrypted
TEXT unsigned encrypted
TEXT signed encrypted

Additionally attaching mails with encrypted attachments (does not matter if signed or not) leads to the same behaviour, which can be seen in the following attachments of the mail Ted:INBOX/Anhänge/attached unsingned unencrypted: all attachment mails (16:30):

attached unsigned encrypted: all mailformats
attached signed encrypted: all mailformats

Notes:

RICH/HTML and encrypted attachements are displayed with their own openpgp-encrypted-message.asc attachment, which in turn can be opened fine (although it's displayed via Kleopatra and only as text not html). Not sure, if this is the expected behaviour

Looks like there is a rights problem modifying the body of those mails
Every time when we try to modify the HTMLBODY or BODY property we fail with MAPI_E_NO_ACCESS.
The attached mails in those tests where ms-tnef formated (winmail.dat)

No change in gpg4win-5.1.0-beta658 / gpgol-2.7.3-beta11_dd853c7 @ win11:

attached unsigned unencrypted: all mailformats
- TEXT signed unencrypted
- TEXT unsigned encrypted
- TEXT signed encrypted
attached unsigned unencrypted: all attachment mails
- attached unsigned encrypted: all mailformats
- attached signed encrypted: all mailformats

I'm retesting with newly created mails, maybe something changed

Note: The fix will only apply to new mails, so I consider the old mails invalid now.

I recreated

mails, with mail attachments (all possible combinations)
nested mails, with the above mail attached

The original issue described in here is resolved in
gpg4win-5.1.0-beta658 / gpgol-2.7.3-beta11_dd853c7 @ win11:

the attachments are always displayed in the same way, independent of the outer mail being signed and/or encrypted.
it's always possible to save the mail attachment to desktop and open it in outlook (with correct content and security level)

Examples for the original cases in this ticket (new mails in ted:INBOX/Anhänge):

attached unsigned unencrypted: all mailformats -> attached unsigned unencrypted: oppgp
- TEXT signed unencrypted -> 0221 oppgp sign text files
- TEXT unsigned encrypted -> 0121 oppgp encr text files
- TEXT signed encrypted -> 0021 oppgp both text files
attached unsigned unencrypted: all attachment mails -> nested unsigned unencrypted: attached unsigned unencrypted: oppgp
- attached unsigned encrypted: all mailformats -> attached unsigned unencrypted: oppgp
- attached signed encrypted: all mailformats -> attached signed encrypted: oppgp

There are other issues for mail attachments now, which will result in new tickets:

display of "Version: 1" as attachment
smime mails are now associated with outlook smime and can't be directly opened
attached pgp mails are often opened in kleo, which might be fine (signature/encryption displayed correct, file attachments accessible)
when opened directly in outlook:
- signed text attached mails have encoding issues (e.g. 0220 oppgp sign text noatt)
- attached pgp encrypted mails don't display the text body (e.g. 0021 oppgp both text files)
- singed pgp encrypted mails don't display attachments (e.g. 0201 oppgp sign html files)
nested signed mail attachments do not trigger the verification (signature is an attachment)
