Workplace will send emails to your users within your instance, for example:
It is essential that emails sent by Workplace are not blocked by your organization's email infrastructure. This page provides the details about the mail servers used to send emails so that you can ensure these emails are deliverable.
Every single email that is sent by Workplace will originate from the domain
Your email administrator must add
fbworkmail.com as a safe sender to your email host, otherwise people in your organization will not be able to receive claim account emails and will not be able to join your Workplace instance.
Your email administrator must whitelist these email origin servers' IP addresses to ensure that your organization does not reject Workplace emails.
220.127.116.11/25 (18.104.22.168 - 22.214.171.124) 126.96.36.199/25 (188.8.131.52 - 184.108.40.206) 220.127.116.11/25 (18.104.22.168 - 22.214.171.124) 126.96.36.199/25 (188.8.131.52 - 184.108.40.206) 220.127.116.11/25 (18.104.22.168 - 22.214.171.124)
To prove that emails coming from
fbworkmail.com actually originate from Facebook, Workplace uses the industry standard technology DomainKeys Identified Mail (DKIM).
Your email administrator should configure your mail host to verify the DKIM record of all Workplace emails to ensure that you do not accept spoofed emails.
Even if your mail host accepts emails from Workplace, it is still possible that email clients like Microsoft Outlook will mark an email as Spam or Junk. In this case, a person would have to check their Spam or Junk folder to find the email. If possible, your email administrator should centrally push a rule to all email clients adding fbworkmail.com as a safe sender.
Work with your email administrator to add the
fbworkmail.com domain as a Safe Senders list in your organization's email client for all of your people.
