How to use Microsoft Office 2016 behind a proxy?
The problem is related to the fact I'm working behind a proxy.

After reading this article     Microsoft Office 2016 and proxy URLs.

I've added the following url's:

nexus.officeapps.live.com
ocos-office365-s2s.msedge.net
config.edge.skype.com
officeclient.microsoft.com
odc.officeapps.live.com
store.office.com
omextemplates.content.office.net
nexusrules.officeapps.live.com
templateservice.office.com


to the bypass proxy list by going to : System Preferences -&gt; Advanced... -&gt; Proxies and filling the field Bypass proxy settings for these Hosts &amp; Domains

P.S.: the domains must be separated by commas.

== EDIT ==

Today, I tried to refine this list given by the above mentioned article and I discover that Word was still running fine even without the list. Apparently, it's needed only on the first start of the application.
