I recently moved a user from pop3 to an exchange account in Outlook 2007. Everything worked well until he realized his many custom categories were missing. When you open a contact and look at the category, it is white and says the master category list is missing.
I did some research and ran "Upgrade to color categories." It gives me a prompt saying it will take a while, I click through, nothing happens, and his categories still do not appear. This appears to be the case for many people in online forums, but no one has a solution.
I also created another profile and imported his PST backup into this account. Still no master categories.
Any ideas? Thanks!
