getting multiple error messages

have received many error messages today with this info, but cannot find the email in my outbox or draft
how do I resolve this?? Thx

The outbox is actually a local folder.  Go to menu/tools/settings/general and in the general tab make sure “Show local folders” is checked.  You can then delete the offending email from the outbox.

Thank you!  Problem solved.  You are the BEST!!!
