Thunderbird keeps wanting to add attachments when sending

Question

Every now and again Thunderbird keeps wanting to add attachment even when there is no attachment. It just just sits there waiting doing nothing. Cancelling this and trying to resend email just tries to add attachment again. Close the program and re-start is the only way to stop this - any ideas - thanks :)

Answer 1

I'm not an authority on this, but here's a few things you might want to check.
First Idea:
- Click "Tools"
- Click "Options"
- Click "Composition"
- See "Check for missing attachments." If box is checked, uncheck the box.
- Click "OK" to save setting.
- Tip: Make sure this is the setting on all computers you are using (work, home, etc.)
Second Idea:
- Do you have the word "attach" or "attachment" in the message, OR THE SIGNATURE? If so, and if the "Check for missing attachment" is set to do so, when sending e-mail Thunderbird detects your e-mail has the word "attach" or "attachment" - end result you get the pop-up message asking "Did you forget to attach a file?" or words to that effect.
Third Idea
- Are you using a pop-up blocker in your browser? If so the pop-up attachment message may not appear. (This is because Thunderbird works in conjunction with the FireFox browser. So the pop-up blocker activates when checking or composing e-mail.) To deal with this simply make a Thunderbird exception in your pop-up blocker, telling the blocker to not block pop-ups in Thunderbird.
HTML Issue?
You may want to try sending e-mail as text only, not HTML. There might be some hidden HTML code when you are drafting e-mail. (This is just a guess, looking for solutions by process of elimination.
Reply or Forwarding Issue
- By chance does this happen only when you are replying to e-mail, or forwarding e-mail. (And if either of those e-mails have the word attach or attachment the program could be "freaking out" when it can't find an attachment.
- Could it be that your anti-virus is set to check e-mails before sending and there's some kind of conflict? Set your anti-virus not to check e-mails.
Lastly
Go to "Account Settings"
"Return Receipts"
Turn off that you want a return receipt. See the other settings and tinker with those to find what might be the problem.
Bonus Tip:
Go to "Tools"
"Account Settings"
Do you have your e-mail set to include a signature, such as a warning for mistakes in transmission, or whatever.
Is the "signature text" box checked, to use HTML?
Are either of the signature type boxes checked? (attach from a file; vCard). Do you NOT have a signature file, is it possibly pointing to a file that no longer exists?
Simply remove the check mark from all boxes. See if this is asking you for a signature attachment, that's not there.
Bonus Tip:
I assume you have uninstalled Thunderbird and reinstalled a clean copy.
