Attach files to your Calendar event so that everyone invited has what they need to prepare for the meeting
Allow your guests to look through the relevant files by attaching reports, presentation slides or any other materials you want to discuss before the meeting, so they can come prepared. It’s also a great way to look back and see what you covered.
