Sometime today 50K emails going back 14 years disappeared from my phone (iPhone SE, iOS 11.4), which is the only device I've accessed Comcast email with over the last 8 months. Checked on a desktop browser (Win 10, Chrome and IE) and have the same emails my phone shows, which date back less than 24 hours.
We left Comcast for Fios 8 months ago but with the understanding the email account would still be active (which it is, can send and receive without issues) but my call to customer service proved futile as I now wait for a call back from account security (no clue what they can do for me) since the CS rep had no answers.
While I wait for Security to call, any idea what the issue is or who to talk to for resolution?
Do you have the account enabled in a desktop email client like Outlook or Thunderbird using POP3? Or in a mobile app using POP3? If so, it may be downloading the emails when you check your account, then deleting them from the server.
