How to add Fred to meetings or prevent Fred from joining meetings?
Fireflies initiates the process to join your meetings a little ahead of your meeting time to ensure we never miss your meeting. To add or prevent Fred from joining meetings ensure that you toggle the meeting at least five minutes prior to the meeting start time.
What meetings get toggled on?
Your meetings are toggled based on the settings you've configured to invite Fireflies to your meetings.
Important things to note:
1. For users who have configured Fred to join all meetings, you might notice that certain meetings are toggled off. This is since Fireflies automatically schedules meetings only two days in advance of the meeting start time.
2. For users who have configured Fred to join only meetings that you invite, you will see all the upcoming meetings on your calendar. You can toggle the meetings you want Fred to join from this section.
Some of my meetings are not visible in this section
The upcoming meetings section fetches meetings from the calendar - either Google or Outlook - that you have given Fireflies access to. Fireflies will not be able to join your meetings that are present on calendars present on other tools like Microsoft teams or Zoom. These meetings will not be visible in the upcoming meetings section as well.
