Scheduling and managing events using Outlook.com calendar
Hi, @J Mayo
Do you mean you want everyone who has access to the shared calendar to see the same category names and colors on the calendar events?
For example, if you assign "Meeting" as Blue or "Holiday" as Green, you want everyone to see those same colors and categories.
If yes, Outlook.com does not currently provide a way to share one common category list and color setup with everyone. Categories and their colors are generally managed separately by each person's Outlook account, so another person may not see the same category color you assigned.
The color of the shared calendar itself can also be changed individually by each person in their own calendar view.

Thanks!
