To give a bit of Context I work in IT and although I don't special in Thunderbird by any means, I have set up multiple users with Thunderbird, I've migrated from Windows Live Mail (WLM) plenty of times in the past.
I had a customer who was using WLM 2012 on her laptop and still using the POP settings.
I was trying to migrate her out of Windows Live Mail into Thunderbird, used the Add-On "ImportExportTools NG" to import the emails that I was able to successfully Export from WLM.
I've used this Add-on several times with no problems, not that I believe the issue has anything to do with the add-on but I believe giving the most information to help resolve this issue is best.
After the e-mails were imported into the Local Folders, there was 2 Parent Folders with a lot of sub-folders which she sorted her e-mails into.
Both folders uploaded successfully, I can login to Webmail with her e-mail and I can see all the folders, all of the emails that I've uploaded all show up and are accessible.
Now, when I look in Thunderbird, I can see ALL of the folders, both Parent folders and ALL sub folders. In the first Parent Folder I can see all of the e-mails that are in each sub-folder without a problem.
Second Parent Folder shows all of the subfolders, but it does not display a single e-mail throughout any of the folders.
-Clicked on each folder for it to "Update"
-Tried to deleted the .MSF files related to those folders, no change.
-Tried to go into the Properties and ensure that these folders were Subscribed.
-Tried to Repair the folder(s)
-Tried to select Download Now under Synchronization
-Tried to edit the Retention Policy in case there was somehow a setting on the mail server that was stopping them from display.
I then simply Uninstalled Thunderbird, deleted the entire Thunderbird folder from %appdata%\Local that contains the folders and information, but when I re-added the account it re-downloaded everything Except that same problem folder...
I'm hopeful that someone has ideas as to how to resolve this type of issue, if there are any ideas please share them. I'm quite comfortable doing some advanced tests/fixes.
Thanks in advance.
