My wife is an ardent and long-time Thunderbird user. She has tens of thousands of old emails organized into dozens of folders. Recently she noted that many folders contained scrambled emails. For example, an email titled "The race to re-design sugar" from Sept. 2020 now contained what looked like content from an email from Office Depot. See below for a short piece of the body of the email. Anyway, I ran Thunderbird's "repair folder" function and not only did it not unscramble the emails, it also seems to have deleted any emails prior to 6 months ago. Fortunately I've got her T-Bird profile file backed up daily, so was able to restore the original (but scrambled) emails. Any thoughts? I use outlook, but I've got pretty good PC skills if you need to take me into the weeds. Thanks! Example of one of the scrambled emails: ''''''From - Sun Feb 4 12:28:28 2024 X-Account-Key: account5 X-UIDL: AEZHkUhl+QCXZb/zNgpcWOY28vQ X-Mozilla-Status: 0009 X-Mozilla-Status2: 00000000 X-Mozilla-Keys: Received: from 127.0.0.1 by atlas-sbc-production.v2-mail-prod1-bf1.omega.yahoo.com pod-id atlas--sbc-production-bf1-7448fd4479-zt82t.bf1.yahoo.com with HTTP; Sun, 4 Feb 2024 20:27:34 +0000 Return-Path: <error@em.officedepot.com> X-Originating-Ip: [20.57.66.208] Received-SPF: pass (domain of em.officedepot.com designates 20.57.66.208 as permitted sender) Authentication-Results: atlas-sbc-production.v2-mail-prod1-bf1.omega.yahoo.com; dkim=pass header.i=@em.officedepot.com header.s=officedepot; spf=pass smtp.mailfrom=em.officedepot.com; dmarc=pass(p=NONE) header.from=em.officedepot.com; X-Apparently-To: xxxx.xxxx@att.net; Sun, 4 Feb 2024 20:27:34 +0000 X-YMailISG: T.w7qP0WLDtIndBfVsii11yVLG9YUwuh8bXrpNWGHf2Ezt9n W35tfL8ReGJq0phUGg1KeSNel41YbOoogg21rDC6q0i7xvo0jIbdikP0kWCS ''''''
