I use open emails as my to-do list in Outlook 2007. For instance, when I look at my Inbox in the morning, I open all emails which I need to respond to, and throughout the day read, respond to and close each one. It's an odd system, but it's how I manage my emails.
Are there any add-ons available which will save open emails and reopen them if Outlook is restarted? I'm looking for behavior like Firefox's tabs, which will reopen each one if the process gets killed.
