I installed version 3.1.4 and I hoped that flaws with attachment were solved. However, the current version works fine if no attachment or an ASCII attachment is present. If I upload a pdf for example, it will not work.The mail will simply not delivered. No action on the screen visible.
I use Windows 10, 64-bit, version 1803, build 17134.345. Outlock 2016 is used with GpgOL add-on in version 2.3.1.
I would appreciate your support on this matter!
