"message size exceeds system limit" repeated infinitely

Hi there!
Some hours ago I sent an Email that was too large and I got the errror message “message size exceeds system limit”. OK so far, but unfortunately this message is repeated every two seconds and doesn’t stop. Apparently EM-Client tries to send the mail again and again. Is there any way to stop this?
Found one or two threads dealing with this issue but no solution for repeated messages.
Best regards - Ulrich

In eM Client, right-click on Smart Folders and choose Display > Outbox.

Now click on the Smart Folder Outbox, where you will find the offending message and can delete it.

That’s great, took me some minutes to find that folder as my EM-Client is labelled german but the offending message was there and I deleted it. Thank you so much for your support!
