Over 6 years of Sent Email is missing
I just discovered that a block of Sent Mail from March 2016 to August 2022 is missing from my sbcglobal.net account.
I don't see anyway that I could have deleted a chunk of that size from my account. Especially when I have history going back to 2003 when I probably opened the account.
I use the general Mail app on my iPhone. and I use web based Yahoo mail through Google Chrome on various laptops.
Also, how can I update Settings to prevent anything like this happening in the future?
