Years ago I used Explorer. I used to "send" link or page by clicking file. I did this after setting 'mail' as the priority program/app and under custom as well.
I am only doing this as an experiment. with Explorer 11.
I do the same thing and all I see under file>send>is a grayed out link or page.
I did everything I used to do including signing in and rebooting.
Explorer 11 is so slow and it keeps saying it is not responding, taking too long and something about script. I sent feedback 4 times.
What am I missing?
P.S. I checked settings>default apps and it is there.
Please do not forget this is only an experiment so do not take it seriously.
Unless I have something wrong, it is an inoperable, slow as molasses, beast.
