My Yahoo Mail had all my emails from when I was in college on it (back when people used to chat with each other via email, also AIM). I still used it sometimes for collecting junk mail and as a backup address for my gmail, or to reread a few of old college emails once in a blue moon, but otherwise rarely logged in. Apparently it had been a year because I got that same message as you did. What a shock.

Never been an issue until then (I must have gone over a year without logging in at some point before then and still was able to log in), and then suddenly 'screw you, a chunk of your past is gone with no way to recover it'.

I was so upset when I realized what happened. I'm still annoyed by it. I know I should have exported it all away a long time ago so it's on me, but I didn't think to do so, I had gotten so used to it always being there.

A year of inactivity before total deletion is way too short for email, imo.

I totally agree with you. I wish they had tried to send me reminders to download my emails atleast. Sad.
