Negative, the solution is for the first shirt, wing douchebag, CGO assclown, etc. to STOP filling everyone's in-container with 6-9 ppt announcements and various emails per day. Literally 90% of my email is completely bullshit that I care 0% about. Luckily someone smart invented the auto-delete rule in Outlook, which helps mitigate these retarded emails decently, but still some sneak through. Most users are not the problem, it's the dumbasses who send mass spam mail 10 times a day.
Comm killed that possibility long ago.
