PGP/MIME e-mails are not decrypted

Description

Already searched a lot but did not find a solution for this:

The gpgol-add-in just shows "Unsicher" (unsave?) and the attachements shown are "Version.txt" and "Message.pgp". I get this in a Windows domain using Outlook 2013 and 2019 Business Premium. If I check the identical e-mails outside the domain the decryption works perfect. I already deinstalled AV (Kaspersky), disabled all other add-ins and checked all GPO but did not find a reason for this behaviour. The log has no Error I just found:

10:52:22/10360/oomhelp.cpp:gpgol_openProperty: OpenProperty failed hr=0x8004010f MAPI_E_NOT_FOUND
10:52:22/10360/mapihelp.cpp:mapi_get_body_as_stream: OpenProperty tag=84470102 failed: hr=0x8004010f
10:52:22/10360/mapihelp.cpp:mapi_change_message_class Message is not a crypto message or already in the right class.

Maybe somebody can give me a hint whats going wrong? Thanks in advance for any help on this!

The problem ist not an "ugly error message" but it does not recognize that the e-mail IS encyrpted by Symantec-PGP! But the plugin always says:

12:25:51/25100/application-events.cpp:Invoke: Creating mail object for item: 34145fa8
12:25:51/26604/windowmessages.cpp:do_async: Do async with type 1108 after 0 ms

12:25:51/25100/mailitem-events.cpp:Invoke: Non crypto mail 2956f1d0 opened. Updating sigstatus.

And that's not correct saying "Non crypto mail"!

If I open the attached "Message.pgp" externally then cleopatra immediately decrypts the message. But the I have the result in the file system as an "eml" file that Outlook is not able to handle. I can see the correct content including attachments in Thunderbird.

Noticed this issue while searching for a different one.
I think this could be fixed with T6686 if it has not already been fixed by a previous change that relaxed the detection of the encrypted message part better.

I am closing this, for now as this issue lacks actionable details, we would need an example mail or debug data. So my intent is just to close it and reopen if the issue still occurs with Gpg4win-4.2.1
