We simply want to send a meeting invite that has a color category assigned lets say "red" and the color is red.
When we send the meeting the recipient does not get the red category, they get whatever their default category is usually blue.
We are on Exchange 2013 and Outlook 2013, there is NO default rule in Outlook to "clear categories" that is apparently for older versions of Outlook so that is not the issue.
We have also set the set-casmailbox -clearcategories to $false , so Exchange server itself should not be removing them.
None of this works. So having said all that, does anyone know how to send a meeting with a color category and let the recipient see it?
