Re: Unable to Activate Office 365 Office 2016 proplus on Windows 7 SP1 machine I would suggest one of two ways, as I have had the same issue. Get off your network. I am unable to activate Office 2016. I am trying to upgrade a user from Office 2010 to 2016. I removed 2010 then used a license code to download and install office 2016. I tied it to my Microsoft account, then followed the instructions to install it. The program installed properly and all is well - EXCEPT I can't activate it. Open any Office app. You can activate Office from any of the included Office apps, such as Microsoft Word. To open Word, open Finder, select the Applications folder, and then double-click Microsoft Word in the 'Microsoft Office' section. It's 30 activations on Office 2013 per Microsoft account. I've got multiple email aliases pointing to the same domain mailbox to handle that. Office 2016 seems to handle the product key/activation process the same way, I can only hope there is a higher threshold for number of allowed activations.
Downloading Office for Mac 2016 from Office 365subscription seems an easy task. Unfortunately it doesn't always go as planned. It seems to be able to use it with corporate resources it needs to activated. While the activation of products that are bought directly at Microsoft with your standard account is trivial, with Office for Mac thru Office 365 corporate subscription requires additional setup on on-premise infrastructure including ADFS servers. As this wasn't our task and we simply got a license of brand new Office for Mac to play with, we didn't expect to have any problems with it. At least not on the activation process…
After installation of Office 365 with corporate credentials, we've started Word 2016 and got a nice screen asking for activation of Office for Mac. Since we already have product bought as corporate client we choose Sign in and follow to next screen.
Unfortunately for us just after going thru entering our corporate email address the error shows up.
Similar errors as the one below have been described on other blogs but none was able to solve our issue.

Solution
After a lot of going back and forth with different settings, and nothing really helping finally we've shut down one of the ADFS servers and things started to get better, where we actually get asked for password.
Office Setup To Activate
Shutting down the working server and starting back up the other one gave us the same problem again. It seems the blame was totally on bad ADFS server that will need to be verified further before going into production. After entering password checking for license started
And as soon as it was found… activation process began.

To finally give us the Good News! Office for Mac 2016 from Office 365 package was Activated.
