Enabling email notifications from Box
Box uses an email service provider to deliver notification messages, such as invitations to collaborate on content when a file has been shared. To ensure your organization can receive notifications from Box, you may need to update your filters to allow email notifications to reach your users. This means you must allowlist the Box email servers that send notification emails.
If your organization uses email filtering, have your mail administrator allowlist (add as a safe sender) the following email address:
And, if necessary, allowlist the following (sub)domains:
Allowlisting specific IP addresses is not recommended because Box IP addresses are subject to change. If your organization requires filtering specific IP addresses, then reach out to the Product Support team.
Testing email delivery
After you allowlist Box email servers, use the Box Admin Console to test whether Box email notifications are getting through. To do this, from the Admin Console, navigate to Enterprise Settings > Notifications tab. From there you can use the Email Test section to send a test notification.
