One of our customer sites isn't working. We are setting up Office 365 proplus to have the setup files downloaded to a share on the server from which the clients will then install from. This works fine on other customer sites but on this one the office setup logs are showing proxy errors and the cab files etc are not being downloaded.
The proxy is set to bypass these addresses: officecdn.microsoft.com;officecdn.microsoft.com.edgekey.net;officecdn.microsoft.com.edgesuite.net
Thanks John for the info. It turned out to be a firewall / port issue in the Smoothwall config and not the proxy. I thought this would only need port 443 for SSL but the customer ended up opening all ports to get it to download.
@Nigel ArcherI also noticed that the Office Deployment Tool had an updated version that allows for downloads on other ports, other than Port 80. Might want to make sure they're using the latest version of the ODT. There's also a couple powershell scripts in the TechNet Gallery for downloading the Office 365 C2R Bits without ODT. I found the below quite useful since I have to download the bits for each Update Channel every month to keep our install packages up to date.
