To help meet Securities and Exchange Commission (SEC) compliance requirements, Calendly stores all outgoing messages (like reminders, reschedules, and cancellations). These messages are logged and can be downloaded from the admin center.

How to export the outgoing communications log
You can download outgoing communications as a CSV file from your admin center. Calendly deletes this data every 90 days.
- Go to the Admin center.
- Go to the Security page, then the Activity log tab.
- Select Export, then choose Outgoing communications.
- A CSV file will download automatically, or you'll receive an email with the file.
To access Calendly logs remotely, use the List outgoing communications endpoint. Only Calendly owners or admins can take this action with the Calendly API.
Extending the retention period
By default, Calendly retains outgoing communications for 90 days. If you need more time, you can request an extension of up to 3 years.
To change your retention period, contact our support team. You can choose any duration between 90 days and 3 years.

This change isn’t retroactive. It won’t recover messages that were already deleted, but it will keep future communications for the new time frame you select.
