Authentication errors when trying to send outgoing messages
Hi there,
When attempting to send emails through Thunderbird, I get the following error messages:
Login to server smtp.long-mcquade.com with username X@long-mcquade.com failed.
Sending of the message failed. Unable to authenticate to Outgoing server (SMTP) . Please check the password and verify the ‘Authentication method’ in ‘Account Settings | Outgoing server (SMTP)’.
When testing the server connection in server settings and outgoing server settings, I successfully establish a connection, yet I am still unable to send messages.

Do the email provider's SMTP requirements match the thunderbird settings? That's the first place to check.
I'm not sure how to check my email provider's SMTP requirments. I do know that my Thunderbird settings are identical to my coworkers and they are able to send emails no problem.
Well, you an usually find on their website or ask. You can also compare yours to your coworkers. I placed a screenshot here to show where the SMTP settings are located.
