I recently noticed that some of my local folders are missing. Not all of them, but some of them. Following some advice we found in the forums, we closed Thunderbird and then deleted the .MSF files from the Local Folder. When we restarted TB, we had more of the local folders, but were still missing 18 of them in the alphabetical order they are listed in. I created a new profile and copied the local folders over to the new profile. When I started TB using the new profile, there were fewer local folder listed than before. Went back to the previous profile and had the local folders that were still missing 18 folders. I see that there maybe a bug for this being researched as I saw 4 other posts in the forums regarding this recent problem and wanted to get my problem noted also. Thank you.
