Processes in Microsoft 365 Insider for installing preview builds, activating subscriptions, and keeping apps up to date with the latest Insider features.
First I want to thank all of the people that did their best to help with this problem. I was pleased and amazed at the response to my request for help. Thank you one and all. I have found the problem and wish to share the fix. In desperation, I attempted to register the Excel program. It Worked! Internet access was instant and allowed registration for Excel. I tried to see if booting in “Safe” mode would allow the Word program to access the internet. It did not. Then I ask what programs could block internet access for one program in Office Suite and not others. I have installed in my Apple MAC Book Pro, a Version 10.9.14 of Intego NetBarrier. As instructed when installing the new Office 365 suite, I turned off the NetBarrier so it would not interfere with the installation. After installing and rebooting I turned NetBarrier back on. After guessing my problem had something to do with the firewall, I looked at the NetBarrier applications and applications rules. That is where I found three Word rules that were in contradiction to my operation of Word. One rule gave Word “Allow Connections”. Two rules BLOCKED all access to Word! I hit “Edit”, removed both Blocked entries and Eureka! Word registered and has worked perfectly since. Hope this helps others.
