Smarter meetings with Skype and OneNote
Outlook helps you schedule meetings with other people, but you can also create an online meeting and set up a shared space for meetings notes before you send your meeting request.
Once you've added attendees to your meeting, select the Skype Meeting button on the ribbon. An online meeting will be created automatically, and a link inserted into the meeting request.
For shared notes, select the Meeting Notes button. You can create a new OneNote notebook or select an existing notebook. A link to the notebook will appear in the meeting request.
