I am using Thunderbird in Windows 11 on an Intel NUC 12 computer. I am using Thunderbird in pop mail for gmail.com and mail.com. I save all important messages daily to Folders in Local Folders. Today I attempted to look for messages in one folder named Family and Friends and found that messages older than 2/14/2024 are missing. I checked other folders and found that they seem OK with messages going back 5 to 10 Years. I tried running repair but nothing changed. Any idea where these files can be? I do have backups of the app data for Thunderbird and am considering to try a prior version but I'm afraid I might lose new saved messages. If I tried to Archive messages, could this be the problem? I have looked in Archive and found very little. Any help would be appreciated. Frank Please ignore this question. I found my older messages.
