Windows 10 Pro x64, 17134.48
Outlook 2016 x64, Version 1804 build 9226.2126 Click to run
GpgOL 2.1.1, part of Gpg4win 3.1.1
- Start Outlook, make sure that the GpgOL addin is loaded.
- Drag and drop the this msg to a test folder (don't do it in Inbox or the default startup folder, or you'll have a startup crash loop requiring Safe mode!)
- Left-click on the e-mail in preview.
Result: Outlook force closes; OK with the GpgOL disabled.
Strangely, doesn't happen if the e-mail is opened directly.
