A co-worker asked me how to send an email in Thunderbird from the company support email address. The co-worker only occasionally needed to send emails from that account.
The co-worker did not want to create a new account and did not want to receive emails from the support account. The question was somewhat related to my recent discovery about not easily disabling accounts in Thunderbird. There is no way to avoid an occasional “oops” moment with manual checking.
The previous solution?
Write the text in LibreOffice Writer, save the file to disk, copy the file to a USB stick, transfer the USB stick to the office computer, open the LibreOffice file, copy the text, paste the text into an Outlook mail.
I suggested the co-worker use webmail to send the emails. No messing with Thunderbird and no sneaker net.
