In Outlook 365's calendar, it's easy to assign multiple categories to a single event. However, only one color shows as primary (the background color) and all other categories just show up as a dot of color on the side.

This would be reasonable, except that it's always the last category that's applied which dictates the background color. The only way I've found to change this is to remove one of the other categories and then re-apply it. If I then want to add yet another category, I need to repeat the process to ensure the primary color is the one I want.

Three events with the same categories

Is there any way to select which category/color provides the background color, without having to add and remove categories?



This has been an issue with all versions of Outlook. You've found the only solution (workaround) that exists for this problem.
