I have always used the organizer in outlook to separate emails by color from certain users. This is now found in conditional formatting in Outlook 2010. I have set up my colors for users but the problem is they keep getting deleted. It happened 3 times in the first week and they stuck for about 6-8 weeks before happening 2 more times this week. When I go back in to conditional formatting the rules are gone and have to be recreated. I am using outlook 2010 in cached mode. Any suggestions?
