Cannot activate Office Apps with High Sierra

I have deleted everything and re-installed High Sierra on an old Macbook Pro. I have an Office 365 account and downloaded and installed Office (version 16.43). When first trying to use any of the Apps (Word, for example), I get a welcome page telling me all the great things I can get and then a window to enter in my Microsoft account email address. I then get a blank window where, when logging in to my account from a browser), I would need to enter my password. The blank screen never changes. Having done a clean install of the OS, there shouldn’t be any remaining bits of Microsoft licence.

Various web pages give conflicting advice about whether or not Office can still be used, albeit without support, or not with High Sierra. Can anyone give me the latest firm evidence about the situation and, if it is possible, suggestions as to how I can activate Office 365?

    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.

    Hey rafaelfonte22, a few tips/screenshots regarding what to look for within the mitmproxy window (Step 7) would be great please. Got it working easy enough, but the web requests appearing aren't jumping out at me in line with your github steps. Thanks in advance.

    Wow, this description is very much appreciated. I'm floored this week with the very same issue you're all describing and I'm extremely impressed with your workaround. If you're able to post screenshots, that would be amazing, as this is definitely above my skillset. Nice work!
