Sometimes you need to provide a hand out or file to your meeting participants, such as a copy of the presentation you’re sharing or a document that they need to review. You can upload the files directly into the meeting in advance, and then the other people in the meeting can download it onto their computers.
You can do this right after you schedule the meeting. Just sign in to your meeting and add the handouts.
Attach a file in the meeting
Pause on the presentation (monitor) icon, and click Add Attachments.
Browse to the file you want to make available for download and click Open.
Click Manage Attachments > Permissions to choose who can download the file, or remove it.
Meeting participants can then download the file from the presentation menu on the Manage Attachments > More option.
