I use Outlook 2007, an iPhone, and two iPads to access my email. Many of the emails go to all the devices, which means going through on each device and deleting mail that has already been read on a different device. I have three main email addresses plus others, and I get hundreds of unopened emails on the phone after I’ve gone through them in Outlook. I use Outlook to filter for junk mail, but after a few days get behind–especially having to delete messages one at a time on the iPhone or iPad. Is there software to help or a strategy that will reduce the redundancy?
