I just checked, the old MIME problem with Click-to-Run Outlook and Exchange Online is still there with Gpg4Win 3.1.7 and Outlook “1903 (Build 11425.20204 Click-to-Run)”.
However, while checking that, I noticed another thing too.
The GpgOL status fields in the header section of the Outlook message display pane that usually are colored, say, green and blue if everything’s fine… they occasionally display without colors. As in, just black text on a white field, black border.
Haven’t had this happen with the first PGP message selected yet, but when looking at several in sequence might get this on the second message… or fifth, or… and then the next one usually is properly colored again.
Only once so far did I get one of the fields colored and the other B&W, but that has happened too.
Now, this kind of symptom is where I start to get nervous about race conditions, array bounds misses, memory leaks and such. Not that Outlook ever was particularly safe about those…
