I've never had problems with my Verizon email account on my iPad3 prior to IOS 6. Under Settings, I have it set to Show: 1,000 Recent Messages; Delete from server: Never; Deleted Messages Remove: After one week.
My Verizon Inbox used to have lots of messages. But, they've all disappeared after the IOS 6 upgrade!!
I'll periodically use the Windows Live email client on my laptop to download messages which then automatically deletes them from the Verizon server. But, Messages already downloaded onto my iPad's Inbox have always been unaffected by this.
Now, those Messages in my iPad's Verizon Inbox are disappearing. And, I don't know why. After I lost all my iPad Inbox emails, I forwarded some from my laptop's Inbox back to myself so I'd get them to show up again on my iPad. This worked for like a day. Then, this morning, they all disappeared!! What showed up in my iPad Inbox were just a few new emails.
Is some kind of synch occurring? I've googled this issue repeatedly using different phrases, but haven't gotten any results. Am I the only one being affected?
