Updated FQDNs for Office 365 activation through Firewall - are the URLs updated? (Network Steve Forum)

Updated FQDNs for Office 365 activation through Firewall - are the URLs updated?

We are having an issue that the supplied URLs and IP addresses are not allowing activation of Office 365 through our Firewall.

We are using the lists provided here (Office 365 URLs and IP)

Can anyone confirm if these lists are correct?

Our usage scenario is: We block the Internet to students during exam periods, but need to maintain a connection to O365 for activation purposes. Students do NOT require access to Onedrive or Sharepoint services.

We have added the following list of FQDNs to the firewall:

activation.sls.microsoft.com

crl.microsoft.com

odc.officeapps.live.com

clientconfig.microsoftonline-p.net

ols.officeapps.live.com

office15client.microsoft.com

officecdn.microsoft.com

But are still finding that O365 cannot resolve through them. Any suggestions on which ones I need to add the firewall?

Thanks in advance!
