Hundreds of thousands of Gmail users lost years of e-mails, files and chat logs over the weekend.
Experts estimated only 0.29 percent of accounts were altered -- a number they later adjusted to 0.08 percent, which calculates to nearly 500,000 users affected.
The issue is still under investigation, leaving thousands of users unable to read their messages, according to Google's App Status Dashboard.
