I took the time to delete most of the categories in the default Master
Category list and add my own. I then assigned my e-mail items to my new
categories. A few days later, I noticed that the default categories were
back, my custom categories were gone and in the Available Categories list my
custom categories were listed as (not in Master List). I am using Outlook
2003 on an exchange server. This does not seem to happen to my co-workers,
neither can they reproduce this behavior on their machines. I have had this
happen several times. What am I doing wrong?
