I have a rule set up in Outlook to move emails with a certain subject line into a specific folder. It works great and has for years. The issue is that I often leave Outlook open on my work computer and then have it open at home as well. Then when one of these emails comes in, BOTH computers "move" it to the specified folder, creating two copies of each such email. I expect that there is no real solution, since rules process much faster than message synchronization...but does anyone have any ideas on stopping the duplication when both computers are running on the same account at the same time?
