Unblock only specific attachment in Outlook

I'm searching for a possibility to unblock a specific attachment in Outlook which was blocked by its file extension (Level1).

E.g. Outlook blocks .exe files. I don't want to unblock .exe files in general but in some specific cases it would be nice to override the block and say

Yes I'm sure and I know what I'm doing

Why do I want this?

When receiving e.g. .doc files which can contain potentially unsafe VBA it would be nice to have an extra warning or extra step to unblock these files. But potentially safe files like .pdf or .jpg would open directly.

Any ideas how to warn from potentially unsafe files but not to block them in general?

This is what Level2Remove/Level2Add registry values were for. But for some reason it doesn't work in Outlook 2016.

Hm this is what I immediately tried after I saw that there is a Level1Add. So sadly there is no information on the net why this isn't working anymore. So thanks for confirming this anyway. – Pᴇʜ – 2016-04-06T12:07:47.247

Leve 2 is safe attachment, but forces to save to disk. https://support.microsoft.com/en-us/kb/829982 KB could be out of date, but support is listed up to Outlook 2010 for Level 2 attachments.
