Thunderbird Support Forum

Dear Sirs, I'd like install the same file ofThunderbird I use in my Computer Optiplex (joerg-hager@t-online.de) on my Laptop and unfortunately, I've forgotten my Password for Thunderbird. Please can you help me? I'm sorry, I'm really a "Greenhorn" in using a Computer. Kind regards, sincerely Jörg Hager

What are the correct settings for email accounts in Thunderbird? On my new computer my accounts were setup in imap with SSL - but then changed to TLS, but I continually get this message " Non-overridable TLS error occurred. Handshake error or probably the TLS version or certificate used by server imap.actrix.co.nz is incompatible." I have a Dell Vostro 5620 laptop with Windows 11Pro. For my email accounts which settings should be correct for incoming and outgoing? Thanks - Graeme

I used to have Address book on my menu bar and could right click on a mailing list and send a BCC email to all. In 102.3, the address book is now in a tab to the left of the window, and I cannot click to open an email to all. I cannot select, and copy all addresses in the list and copy to a new mail BCC field.. How can I now send an email to all in a mailing list? It used to be so simple! John
