Unable to send emails with thunderbird
One of my clients are unable to send emails with Thunderbird.
I have verified that their webmail account is working, have checked smtp settings (same across all 600 sites I support)
I have removed account, uninstalled thunderbird, rebooted pc, reinstalled, set account back up. No change.
I get the error "Sending of the message failed."
If I remove SMTP password, i still get this error. It does not even request a new password be entered.

Advise: use the 'Description' field to enter eg: email address which should be the same as the username (full email address) and click on OK
Then make sure the mail account is actually using the correct smtp server for that email address.
- In left pane select the name of account/email address.
- Bottom right, for selected Outgoing SMTP, you should see the email address that you entered in the description field. If it is not the same email address as the account then click on drop down to select correct outgoing server for that account.
click on Ok to save and close Account Settings window.
Close all Write windows - save as a draft if required.
Exit Thunderbird to ensure all settings are stored.
Noted that error does not mention the server, so worth checking the Firewall (which might be part of an Anti-Virus product) is not blocking the 587 outgoing port.
Then restart Thunderbird and check sending.

Exit Thunderbird. Access Firewall. The Firewall must have Thunderbird as an allowed program. Sometimes, after an update or reinstall, the Firewall thinks the updated/new thunderbird is a different program. So even if the Firewall says it allows thunderbird, it is worth unchecking, ok 'ing and then accessing again and setting up Thunderbird as an allowed program and then restarting Thunderbird.
Thanks,
I have done as you suggested, but still not working.
We have windows firewall disabled and a globally managed ESET solution in place.
I've checked ESET and it is not blocking the port.
It also does not allow me to save as drafts, which implies a permissions issue. I have ensured the thunderbird folders in Appdata have full control permissions set, but still doesn't let emails be saved/sent. They are still receiving emails fine though
I have come across eset causing an issue before, so could you please could you try the info as shown at the following link.

Morning,
I tried those steps, then fully uninstalled ESET and no change.
Try changing the OCSP setting in Options > advanced > certificates to not query responders. The test I ran indicated the server does not support it. https://www.immuniweb.com/ssl/?id=V8NWC1dg
