Using Classic Outlook on Windows for personal email, calendar, and contact management
I've had the same issue. I relied on being able to add attachments to my boss's meeting planners so they have the information they need for the meeting without giving it to them in paper. I've been creating a 2nd calendar item NEXT TO the meeting planner to add background, docs they need for the meeting, etc., which just clutters up the calendar unnecessarily and is very inefficient.
