Microsoft has revamped Mail in Windows 11, but users still need to sometimes fix that app. When the Mail app is not working, that either means it doesn’t open at all or users can’t send/receive emails with it as usual. One Mail user said this in a Microsoft forum post:

When sending an email from the Mail app in Windows 11, the email appears to send but then disappears. It’s not in Drafts, Outbox, or Sent folder. It was working fine and then this issue showed up.
