Outlook 2010 - Unable to see any colour besides red under"Categorize" option
In Outlook 2010, a user has been set up for full access to two other calendars - both in the exact same way with the same level of access.
Once an appointment is selected in Calendar1, right-clicking gives the user the option to "Categorize" by a whole list of colours.
Once an appointment is selected in Calendar2, right-clicking gives the user to "Categorize", but only two entries appear in the list "Red Category" (red colour) and another one called "Blue Category" (also red colour).
Installing third party software isn't an option since its a corporate environment.
Any help with this would be appreciated.
