Yay, after only seven years, the latest update to Microsoft Teams lets you past an email address into the 'recipients' box in the make-a-meeting UI and doesn't split it into {first} {second} {email@address} and treat them all as separate invalid email addresses (yes, even the email address, because it kept the angle brackets in the token that it parses. And, yes, it did split between spaces for things in quotes, but it dropped the quotes).
Now, if you paste "Some person" <email@address>, you get that person as an invitee, not Some, person and <email@address>.
Honestly, if I didn't have first-hand knowledge that people in the Office org at Microsoft use their products, I wouldn't believe it.
