Lync Online URLs and IP Address Ranges

Lync Server 2013
 

Topic Last Modified: 2014-04-25

Following are the lists of IP ranges and URLs used by the Lync Online service. Your corporate network must allow your Lync Online users to access these IP ranges and URLs. This includes any device that is filtering web traffic: firewalls, load balancers, proxy servers, web security software/appliances, and so on.

importantImportant:
Update April 16, 2014. A new CRL endpoint was added: sa.symcb.com. Add this new rule to your firewall or proxy server for Outgoing TLS and HTTPS traffic to avoid Lync sign-in issues and ensure a secure connection to Office 365.

For a complete list of Office 365 routing requirements, see Office 365 URLs and IP address ranges. For firewall port and protocol settings, see Ports and protocols used by Office 365.
