There are a few troubleshooting steps to try when emails are not showing up in the Sent folder:

1. Check Spam or Junk Folder:
   Check the Spam or Junk folders to make sure the email didn’t accidentally get diverted.
2. Check Settings:
   Check the email settings to make sure that the Sent items are being automatically saved.
3. Check Server Responding:
   Verify that the email server is responding correctly and that messages are being delivered.
4. Check Network Connectivity:
   Verify that the network connection to the server is active and that messages can be sent.
5. Check Email Account:
   Check the email account to make sure it is still active and can send messages.
