Outlook appointment category colors

Hi,
1) running Mdaemon 20 and Outlook 2019 with IMAP accounts and syncronising calendar appointments using CalDev. From Worldclient it is possible to select the (domain) category color of an appointment but not from Outlook. It seems that Outlook doesnt allow to use category colors with IMAP accounts. Is it true ? Would Outlook Connector solve this problem ?

2) Also, is it possible for a user to set a default category color in his worldclient calendar so that it is possible to add an event with the right color without clicking on "add more detail" to select the color?

Thanks
Luca
