Question
Friday, July 6, 2018 5:15 PM
On my network I have had a rash of users that have their Office 365/Office 2016 ProPlus open up and show as "unlicensed". What address and port does Microsoft use to have office 2016 call home to verify the license? I have a feeling that something is being blocked in this communication and would like to have my network team verify.

Hi Menz01.
As you know, Office 365 client programs must be able to connect to the Internet at least once every 30 days to verify their activation status, otherwise they'll enter reduced functionality mode: you need at least TCP ports 80 and 443 open, of course.
For detailed information refer to the following links
- Network requests in Office for Windows and Mobile
- Office 365 URLs and IP address range
- "Sorry, we can’t connect to your account. Please try again later" error when you activate Office from Office 365
Bye.

Hello Luigi,
the systems that have been failing are all on my corporate network and all have access to the internet 24/7 (minus any outages beyond our control) so that is not the case. before going to Office 365 we made sure port 80 and 443 were open from our network to Microsoft. We do not use a proxy server so that is not it either. I have asked my networking team and they used the Microsoft URLs page to open what is needed as well in the past, I am asking them to review it again in case there are any changes.
when I access the users machines that are showing unlicensed I always verify the user has a license first and they do. I then access their machine remotely and verify they have internet access and they do. I then open their product and it shows as unlicensed. I sign the user out of an app like word and sign them back it and it still shows as unlicensed.
