I have no idea what's going on or how to reconnect my Mail sub-folders with Thunderbird so that I can get my e-mails back. Even the one e-mail account which remains (and is still receiving new e-mail) is empty. So apparently everything is still there, it's just that Thunderbird doesn't know how to access those folders. PCV backup file (1.7Gb), allowing for some compression in the. The total size of the Profile folder is about the same as the latest backup. Based on the sizes of the Inbox and Sent sub-folders in each, my data is still there. The other 4 sub-folders are the name of my ISP's pop server, with -1, -2, and -3 added to the last 3 folders.

One is named "Local Folders" and has the files imported from Outlook. Looking in my Thunderbird profile folder "Mail" sub-folder, I find 5 sub-folders. Then I tried reloading the backup that I had just made, with the same results. My address books and calendar were also empty. When it finished, all I had was one empty e-mail account (instead of three) and the e-mails that I had imported from Microsoft Outlook when I switched to Thunderbird.

First I backed up my Thunderbird (52.2.1) files using MozBackup 1.5.2 beta 1, then I used MozBackup to load the backup file with the deleted e-mails. I wanted to retrieve some deleted e-mails from a MozBackup file I made about a year ago.
