Recently I noticed that in ALL of my Local Folders, I can no longer see any of the content. The headers show like normal, but I cannot open / read the content (presumably contained therein). I have tried repairing individual folders, but nothing changes. I have tried eliminating the .msf file, but nothing changes. A new .msf file is created, but the content is still not visible. If I try and reply to a local email, the email is empty with the exception of the subject. Even though it shows the sender of the email (i.e. From), neither the email address nor the email content is copied into the reply. I am slowly starting to worry that the individual files storing the email content are corrupt, but if I open the content file (i.e. non-.msf file) with Word, I get what I presume is the first / oldest email, but nothing more (even though the files are many MB large). Is it significant that I have both "Local Folders" and "Local Folders.sbd" (as folders)? The content within them appears to be similar if not identical. My email is stored on a NAS which I can access from any computer on my network (presuming I have set up Thunderbird appropriately); can this contribute to the issue? Any other ideas which might lead to such an annoying issue? I really don't want to have lost all my emails for the past 20+ years. Thanks in advance for any suggestions you make.
