If it makes you happy I have same issue with Outlook.com, seems like some emails sent from me are never delivered which would not be so big issue, bigger problems is I am not receiving some emails at all, not even in junk e-mail. My kid's pediatrician can't send me email despite being in safe senders list (he can receives emails from me but his email provider (one of the biggest in Czechia) is rejected), same goes with my wife's gynecologist, they received my emails, but I didn't receive their reply, had big issues to make appointment for her and even receive prescription they sent through e-mail (funnily I resorted to using gmail where I received prescription without any issues, sadly they don't send SMS like any other doctor I experienced), sometimes (but that's rare) I also won't receive company e-mail, though these emails work in 99.5% cases. I have nobody to contact to deal with this issue. I wish I could completely disable any e-mail filtering, since I will rather deal with junk email than not receiving important emails, which is much worse issue my mailbox being blackhole. Also both my Gmail and Outlook.com accounts are very old, Gmail maybe 15 years, Outlook maybe 10 years and I used to received emails from both addresses (pediatrician/gynecologist).
