Yesterday at work I accidentally emailed our entire division on an email I had only intended for a single person. I think I accidentally selected the wrong auto-complete, since the name and the list start with the same letters. I would like to try to prevent myself from doing this again.
The best option would be if there's a way to pop-up and confirm whenever I am sending to certain recipients. Based on this question that doesn't seem possible without installing additional software. That's something I want to avoid, as that requires getting admins involved to approve and install the software for me.
So far the best solution I've found is to create an Outlook rule that delays delivery to certain recipients. Hopefully then I'll notice it in the Outgoing box and can delete it before it gets sent, though I'm not entirely sure whether delays happen at the client side or on the server. If the latter, that won't work.
Are there any other ways I can prevent myself from accidentally emailing specific addresses?
