FindTime shows what days and times work the best for you and the attendees when available using free/busy data. Propose your selected times to all attendees and allow everyone to vote and quickly come to a consensus. FindTime is currently an Outlook add-in for scheduling meetings. Microsoft will soon be releasing an update to Outlook to remove the add-in and adding an Outlook feature called Scheduling Polls.
Once you have the plugin installed in Outlook you can create polls for meeting times. You choose the attendees, time, and length of the meeting. There are also several other options to select:
For meeting polls that you have created using FindTime you can view your dashboard to check the results. From the dashboard there are also settings that can be adjusted. You can review those settings here.
If you have been invited to vote on a meeting poll you can go here for instructions on how to vote.
