I would have thought this is a fairly simple thing but when creating an Outlook calendar event using Flow, I need to be able assign a category! I can't see a way to do this currently.
I need to let MS Flow handle calender items dependend on their categories, e.g. for copiing items from a public calender into another (private) calender.
Would be useful as well to let Flow copy category flaged items from public address folders to private address folders and vice versa.
Thus far, I have not found a solution using flow but this might help you
Henceforth, whenever you create new appointments whose subjects contain the key word “subject” will be color categorized automatically according to your conditional formatting settings before.
This doesn't work with online calendar though
