I prefer to manage my Calendar by assigning colours to different types of event i.e. red for critical, blue for travel, green for vacation etc. I do this through the settings and then conditional formatting. I then add each new category and assign it a colour, and then click on the condition button to add a search word for each category, and when I come out of settings it then captures each colour onto each relevant event on my calendar. Sadly whenever I come out of outlook or shut down/restart my computer it loses that set up data and goes back to the bland colour for each event again. Any ideas on how I can save the changes permanently? Tearing out what little hair I have!!
