Question about Hotmail for my mom, please? [View all]

She's 95, amazing for her age, and we email all the time. The thing is, she occasionally loses an email in "drafts" and then doesn't know how to send it when she finds it again. She insists that in the current draft email, my address is present in the "to" section but there's no "send" button.

I haven't used Hotmail in decades and have no idea what she's looking at or how to talk her through it. I'm supposed to call her early tomorrow morning to straighten this all out. Can anyone here help, please?
