Meetings in my calendar display show up as an unreadable dark purple. There is a blue option but that is defaulted to a google calendar that I don't use. I can't seem to reorder it so my Outlook calendar is blue. Can this be done?
You can try changing the color settings in Outlook.
In Calendar, click Calendar Coloring, and then click Edit Labels.
You can also try changing the background, or creating a new Google Calendar with a different color setting.
