Hi,

We are configuring deployments of Office 2019 to a number of different customer sites with different proxy / firewall setups. We are using a local server share for deployment of Office 2019 to the clients so this server will need to download the latest Office 2019 versions from the Office CDN. And this is automated with a local system task to get the latest version each month for security updates.

 

What URLs do we need to whitelist to avoid problems with proxy authentication and firewalls?

 

I have had a look at the Office 365 endpoints and the full list https://endpoints.office.com/endpoints/worldwide?clientrequestid=b10c5ed1-bad1-445f-b386-b919946339a... . But the customers are only using Office 2019 at the moment so they don't need to do all of these endpoints.

In the full list there is a CDN.office.net which sounds hopeful but I can't find any dns records for that. So what are the URLs used to download Office 2019? 

 

Thanks,

Nigel

From fiddler traces it looks like it is these : officecdn.microsoft.com and officecdn.microsoft.com.edgekey.net
