As I opened my Charter email in my Mozilla Thunderbird Account in my computer today, I found it to be corrupted with 2,156 total emails in my 'SENT folders' contents with dates ranging from current 2018 back to 2014. The Folder column on the left side of my homepage shows: 'Sent items12...o6-15-2014' with 'Sent Mail 4-9-10 to 4-6-15' just below it.(?) A similar Corruption happened once before which is why you already have my email info "showing already used". I am one in the same: 2nd time around! (the dates' details may not be identical as I don't remember what dates were involved back then, but my email was the same: gigif@charter.net. Somehow, this time may be connected to Window10 since earlier this week, (possibly on Tues.May 8?), when I opened my computer with my password entry, I accidently cliqued in the right column edge of my homepage (was just a reflex action) to enter, instantly causing all my icons on the bottom of my homepage suddenly appeared up & down on the right side edge of my homepage. Now, today, the corruption appeared! I've tried to describe the details to you as best as I can in the sequence that they happened which I hope will help identify the problem. Thank you for whatever help you can give me to solve my problem. gigif@charter.net
