Thanks Replies (13) įrom your description, we understand that you are using Outlook desktop client. When looking at permissions for this group calendar the highest permissions is “can edit.”Īny help would be much appreciated. I’ve been given permission to someones personal calendar where I can see their categories and colors, but I was given delegate access. When creating a new event, they also cannot select a category. They can see the category grayed out but do not see the colors. I’ve added about 12 people to the calendar who have editing capabilities. The calendar was originally setup as a secondary calendar for myself (then I copied it to a group calendar using drag and drop.) I created a group calendar for office events.
