Whenever I go to delete just one email in Thunderbird, every so often it will also delete the email that comes after it. So I have to go into the Deleted Messages folder and move the email back that I didn't want to delete. My Thunderbird stays updated automatically so that is not the issue. I've cleared the Thunderbird cache many times and that didn't fix the issue and my IMAP folders are synced that I know of but not sure about all the folders and not sure how to do that. I didn't have any issues with this until several months ago for no particular reason I can think of. I really don't want to uninstall and reinstall Thunderbird if I don't have to, if there is another fix if anyone has a solution. Couldn't find anything online except for the steps above I already did.
