Dear Madam / Sir: I had Windows 11, all files and applications including Thunderbird reinstalled in my computer, but I am now unable to access existing email server with Thunderbird. In ' Set up your existing email address' there is a password needed that I don't remember and there isn't an option to reset it. So I am stuck. I called Geek Squad who did the installation; they referred me to AT&T (my internet provider); they said they cannot help with Thunderbird. Please let me know what I can do to access existing email server in Thunderbird (attached is photo of setting which appear correct), thank you in advance, Stefan Menzi Architecture Stefan Menzi, AIA [edited out private address, phone#'s and email from public community support forum]
