Opened up my email yesterday (NTL World) using Safari web browser, clicked on one of the new emails and every new email plus most of the older ones in the inbox suddenly disappeared leaving just two messages. Checked out the trash and then looked in every folder with no sign of them anywhere. This also happened about a year ago but I didn't lose as many then. Anyone else had this happen?
Sorry about this strange incident. Do you have any email clients for mail access (such as Outlook, Thunderbird etc)? Do any other devices access webmail?
If the missing mail cannot be located in Trash would you please check Spam (if you've not already done so).
If that doesn't enable you to retrieve them please let me know and I'll dig a little further for you.
I don't normally bother with email clients although I did have MyMail and Apple Mail set up on my phone which I checked and they had gone from there too. I checked all the folders including some I had created to store emails I wanted to keep together. If they can be retrieved it would be good as I don't know if any were important or interesting, though I doubt it, so not the end of the world. Just be good if the reason could be found and something done to make sure it doesn't happen again.
I've checked and I have no filter rules set up or webmail forwarding so guess it remains a mystery. Not sure it's worth escalating now but I suppose there's nothing to lose by giving it a try. Certainly if it happens again I'll make a call straight away - maybe you could put a note on my account somewhere so there's some history. I've changed my password just in case.
