I have a wireless network of PC, iPad and iPhone in my home. I have been sending emails from all devices for over a year now and have always found all of my sent emails on all three devices. Since last week, emails sent from my iPad and iPhone are not listed in the sent folder on my PC, but they are in the sent folder on the iPhone and iPad. For example, the last message in the sent folder on my PC is dated January 19, 2013, and the sent folder on the iPad and iPhone also shows messages sent January 20-24. I have synced, refreshed, reset the modem, turned devices on and off, all to no avail. Anyone know what is causing this?
