Cannot activate Office Apps with High Sierra

Thanks, Rafaelfonte22. I am not in a hurry so I’ll wait for your update as I shall probably need some pictures to guide me.

Rafaelfonte22, that’s an interesting potential solution. I am, however, doubtful that it will work for those of us who subscribe to Office 365 because we do not get any sort of authentication code or product key but need to sign in to our Microsoft account from the app.

This solution works for the case you’re referring to. It involves authenticating to your MS account from the Office App itself by completing the sign-in flow in a web browser and then coming back to it with the code generated upon sign in. I’ll update the gist later with some images to help clarify the steps further.

Hi guys,

I also went through the massive trouble of attempting to install Office in a High Sierra machine just recently. After a lot of back-and-forth, looking for as much info as I could gather from forums like this, I finally got a procedure that allowed me to do it - however, it takes a lot of steps to get there as it basically requires you to man-in-the-middle the whole thing to get an auth code generated and replied back to the Office App. Also, it worked to get all apps authenticated except for MS Teams.

I don't provide any guarantees that this will work for you. If you want to try it, make sure that you know what you're doing, and try it at your own risk: https://gist.github.com/rafaelfonte/56b9fb80daed8c586433e82859ccb876

This procedure involves intercepting the authentication window request url that is called just before the page goes blank with a local proxy tool, going to that URL in your browser, copying the auth code URL and then forcing the authentication window to that URL via a HTTP redirect. Still, a lot more hassle than what should at all be expected, just to overcome limitations from software that is poorly maintained by Microsoft when it comes to supporting users on legacy platforms that were working fine just a few years prior.

Also, I haven't taken any screen captures of URLs or such while doing it. What's documented there comes out of memory alone. I might come back to it later to fill in a few more details in the future.

(EDIT: Just reviewed the doc to make it easier to follow and made a few corrections to make it more clear).

The email address of the Microsoft CEO has been removed “for privacy” but just go to this URL:
