I lost all of my mails
I don't know what happened, but today I noticed that all of my mails have disappeared.
(I noticed a pop-up which mentioned something about "... 12 months...", but -for once- I didn't entirely read the message and just closed it)
Somebody has an idea what could have happened?

If you did not sign into your account within 12 months the account is deactivated and the mailbox purged. Unfortunately, the missing emails cannot be recovered.
