Universal Print – required URLs

A Windows endpoint that is being used with Universal Print needs to have an internet connection, with access to the following internet (TCP/IP – 443) endpoints:

• *.print.microsoft.com
• *.microsoftonline.com
• *.azure.com
• *.msftauth.net
• go.microsoft.com
• aka.ms

Delivery Optimization

For peer-to-peer traffic, Delivery Optimization uses 7680 for TCP/IP or 3544 for NAT traversal (optionally Teredo). For client-service communication, it uses HTTP or HTTPS over port 80/443.

Delivery Optimization will help with band-wide consumption on Windows endpoints:

• *.do.dsp.mp.microsoft.com
• *.dl.delivery.mp.microsoft.com
• *.emdl.ws.microsoft.com
