I have only one Gmail account set up on both my iPhone and iPad with Microsoft Exchange. I have no other e-mail accounts. I also access the one account on my PC. I usually clear emails out of my in-box very quickly as I hate clutter. However there are always a few that I want to keep there for a few days or even weeks, as reminders or what-not. Recently some of those e-mails began disappearing from my in-box on both the iPad and iPhone only. When I look at my in-box on my PC they are still there, where they should be, in my Gmail in-box. At first I thought it was a fluke but it has since happened again and again. I either have to search in my All Mail folder on either "iDevice" for them or forward them to myself from my PC to get them put back in the in-box where I want them. It's annoying. Any ideas on why this is happening? Is it happening to anyone else?
