Why does thunderbird freeze when sending an email?
I've been all over the forums trying to find a solution to this problem.
I've attempted to compact the folder, repair the folder, turned off email scanning (also removed the anti virus), checked the drafts folder for old emails that are slowing the system down. There are no error codes that I can see, This only seems to be happening with some of the accounts added.

Try to start Windows in safe mode with networking enabled. - Win10 https://support.microsoft.com/en-us/help/12376/windows-10-start-your-pc-in-safe-mode
Still in Windows safe mode, start Thunderbird in safe mode. - https://support.mozilla.org/kb/safe-mode
Does the problem go away?
Hi,
Thanks for getting back to me, sorry for the late response.
The problem still persists when thunderbird in safe mode on a normal boot.
Booting in Safe mode with networking, the problem no longer happens.
What are the next steps from here?
Windows safe mode disables anti-virus software, which is most likely the culprit.
Create an exception in your anti-virus software for the Thunderbird profile folder, so that the anti-virus real-time scanner will not scan it. http://kb.mozillazine.org/Profile_folder_-_Thunderbird
Don't let your anti-virus software scan incoming and outgoing messages.
Don't let your anti-virus software scan attachments.
Don't let your anti-virus software intercept your secure connection to the server.
Remove any add-ons your anti-virus software may have installed in Thunderbird.
Keep it working. http://kb.mozillazine.org/Keep_it_working_-_Thunderbird
And last but not least, backup your Thunderbird profile on a regular basis. https://support.mozilla.org/kb/profiles-where-thunderbird-stores-user-data#w_backing-up-a-profile
Again sorry for the late response. The error keeps happening, even after completely removing anti-virus software. I have no addons on Thunderbird. It seems to only be happening when PDF attachments are added to the email.

You haven't been asked to do that. Presumably Windows Defender is now your current anti-virus software.
