Any time mail disappears from the server, there's a pretty good chance there's some device pulling it off. This can happen even without you intending it to. For example, the default Verizon setup for a long time (and possibly still) configured Outlook automatically unless you were paying attention and unchecked the box during the install.
The easiest way to fix it is to change your password. Once the device(s) can no longer authenticate, the disappearances should stop.
what somegirl said is 100% true...your pw may have been compromised from a keylogger...run an antivirus scan as well as a malware scan and if its good change the pw or change your pw now then run the scans and if something is detected change the pw a 2nd time
Yep -- same issue. After squabbling with Verizon (who said I had to have deleted them or I was hacked) I changed my password. Now, today, I find that emails that I had saved specifically to track this issue all disappeared over the last day or two. My last email in my inbox is February 3. Does that sound coincidental? Something inside Verizon email is doing this -- and Verizon won't own up to the issue.
I've also had an issue with disappearing emails- I intentionally kept two emails that I needed for reference, that came in just two days ago. Magically they've vanished, and they're not in my trash folder. This is also not the first time I've had this issue. It's not another device pulling my emails, and it's not a virus. Emails are literally just disappearing with no rhyme or reason. What's up Verizon??? Is this some kind of weird server issue or what? This is really frustrating.
