Other endpoints not included in the Microsoft 365 IP Address and URL Web service

Some network endpoints were previously published and haven't been included in the Microsoft 365 IP Address and URL Web Service. The web service publishes network endpoints that are required for Microsoft 365 connectivity across an enterprise perimeter network. This scope currently doesn't include:

  1. Network connectivity that might be required from a Microsoft datacenter to a customer network (inbound hybrid server network traffic).
  2. Network connectivity from servers on a customer network across the enterprise perimeter (outbound server network traffic).
  3. Uncommon scenarios for network connectivity requirements from a user.
  4. DNS resolution connectivity requirement (not listed below).
  5. Internet Explorer or Microsoft Edge Trusted Sites.

Apart from DNS, these instances are all optional for most customers unless you need the specific scenario that is described.

6 Mailbox Migration

When mailbox migration is initiated from on-premises Exchange Hybrid to Microsoft 365, Microsoft 365 connects to your published Exchange Web Services (EWS)/Mailbox Replication Services (MRS) server. If you need to allow inbound connections only from specific source IP ranges, create a permit rule for the IP addresses listed in the Exchange Online table in Microsoft 365 URL & IP ranges.

To ensure that connectivity to published EWS endpoints (like OWA) isn't blocked, make sure the MRS proxy resolves to a separate FQDN and public IP address before you restrict connections.

15 Authentication and identity FQDNs

The FQDN secure.aadcdn.microsoftonline-p.com needs to be in your client's Internet Explorer (IE) or Edge Trusted Sites Zone to function.

Trusted Sites
16 Microsoft Teams FQDNs

If you are using Internet Explorer or Microsoft Edge, you need to enable first, and third-party cookies and add the FQDNs for Teams to your Trusted Sites. This is in addition to the suite-wide FQDNs, CDNs, and telemetry listed in row 14. See Known issues for Microsoft Teams for more information.

Trusted Sites
17 SharePoint Online and OneDrive for Business FQDNs

All '.sharepoint.com' FQDNs with '<tenant>' in the FQDN need to be in your client's IE or Edge Trusted Sites Zone to function. In addition to the suite-wide FQDNs, CDNs, and telemetry listed in row 14, you need to also add these endpoints.

18 Yammer
Yammer is only available in the browser and requires the authenticated user to be passed through a proxy. All Yammer FQDNs need to be in your client's IE or Edge Trusted Sites Zone to function.

24 Network Connection Status Indicator

Used by Windows 10 and 11 to determine if the computer is connected to the internet (does not apply to non-Windows clients). When this URL cannot be reached, Windows assumes it isn't connected to the Internet and M365 Apps for Enterprise will not try to verify activation status, causing connections to Exchange and other services to fail.

Used by Android and Apple mobile devices to receive push notifications to the Teams client for incoming calls and other Teams services. When these ports are blocked, all push notifications to mobile devices fail.
