Why has Thunderbird started re-downloading old emails?

This started happening a few months ago but I haven't got round to 
posting about it until now. I suspect it started following an automatic 
version upgrade, but I can't be sure.

When I click on a user-defined email folder, the folder is often empty 
initially and then Thunderbird re-downloads all the emails that are in 
that folder. This is mildly irritating when I have wifi access but is 
infuriating when I'm tethering my PC to my phone using 3G, as it then 
costs me money to re-download my emails.

Quite often (but not always), when this happens, all the folder settings 
have reverted to their defaults, so for example, the oldest emails 
appear at the top whereas I always have my folders configured to show 
newest emails at the top; threads are not switched on whereas I always 
configure my folders to have threads switched on, and so on. This is 
infuriating even when I do have wifi access.

I have a gmail email address and Thunderbird syncs with gmail using 
IMAP. However, this problem didn't start until some time after I started 
using the gmail email address.

Is this problem "by design" (and if so why on earth?); or is it a 
recently introduced Thunderbird bug; or is it a recently introduced 
gmail bug; or has something gone wrong with my Thunderbird setup (and if 
so how can I fix it)?

When you installed a newer version of Thunderbird, did you install over
the prior version?  Or did you delete the prior version before
installing the new one?

Thunderbird has just re-downloaded all 300+ emails in my Inbox, with 
their attachments, and changed all my settings for the Inbox folder back 
to their defaults. This is driving my mad! Please can someone help?

Thanks

IMAP or POP3/SMTP?

It could be that your inbox is defective.  You can repair it by

By repairing the folder, TB will first delete everything from it and 
then re-download the messages only once and you are good to go.

Good luck.

I haven't installed a newer version. It automatically updates itself 
from time to time, whenever Mozilla release updated versions.

As I stated in my original post, IMAP.

Many thanks. Presumably that means I should repair all of my folders and 
subfolders, not just my inbox, as they all do this sometimes? As I have 
several hundred folders and subfolders, is there any way to get 
Thunderbird to repair them all in one fell swoop rather than having to 
right-click on each one individually?

I *think* that by repairing Inbox it also repaired all subfolders in my case (inbox is imap).
At least a previous Version of TB removed all my Tags while repairing. I wrote some private addon to save and restore tags.  Klaus

There is a quicker way to repair all folders so I give instructions here 
using Windows 10:

1) Open your File Explorer
2) Open this folder with File Explorer:

<C:\Users\<USERNAME>\AppData\Roaming\Thunderbird\ud28fzkd.default\ImapMail\imap.mail.yahoo.com>

For <USERNAME> use your Windows profile name;
For ud28fzkd.default use your TB profile name created randomly by TB 
when first installed;
For imap.mail.yahoo.com replace with your imap account - gmail, hotmail, 
outlook, aol etc

3) Now sort the files by extensions using this picture as a guide:

https://i.imgur.com/dMkiKLU.png <https://i.imgur.com/dMkiKLU.png>

4) Now delete all files with Extension: MSF

https://i.imgur.com/jebPb9e.png <https://i.imgur.com/jebPb9e.png>

5) Now when you restart TB, all your emails will be downloaded again and 
your folders are now repaired as well. Repairing means repairing the 
Indices of emails or newsgroup posts.  that is all to it.  When Index is 
defective, the emails or posts will be out of sync with servers.

Hope this helps.
