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.

In other cases, the Mail app doesn’t start at all for some users. Users can’t utilize Mail when that app doesn’t open or send/receive emails. The same issue appears for some users on Windows 10, making it a bigger problem than expected considering it’s spanning across OSs.
