I'm tired of having to sign in over and over again so I need a solution for the most modern version of this app so I can fix it. Yes, it's updated and yes, I've tried uninstalling an reinstalling. The issue the users face is Teams or Outlook just refused to log in. The only fix is to delete the Teams folder in %appdata%\Microsoft and delete the Outlook profile and re-create it. We have found on user endpoints that the AAD Broker Plugin is sometimes missing and this is what causes all manner of hell and headache with Microsoft applications/services for end users. The Office 365 repair tool can help you fix the majority of Office 365 problems for installed Office 365 applications (not applicable if you use online apps only).

Once the key is added, and the user restarts Outlook, they receive a legacy authentication dialog box, enter their domain password, and connect to their mailbox without issue. This seems to be our most effective fix, and it’s the one we arrived at after hours of <a href="https://git.tintinger.org/enriqueta73002/tech-fixes-at-fixtechguide1124/wiki/How-to-Resolve-%22Error-0x80004005%22-on-Windows">Help from FixTechGuide</a> forum digging and web searches. Information and fixes from Microsoft have been scant as well, outside of the registry key one.

I have run into multiple Outlook 2016 installations where the only way to get connected to Outlook is to add EnableADAL and set it to 1. These have been fresh Office 365 Business Premium installations, existing Office 2016 OEM installations, and on my Action Pack installation of Office 2016. Try testing the configuration of your Office 365 email system and fix the problems that are preventing users from using the email services. Microsoft Support and Recovery Assistant can help you resolve problems with Microsoft Office, Office 365, and Outlook. Open the required file, hit Share and then check the list of users that you can give the rights to edit a file. You can set access permissions for the entire organization or invite only the users you specify.

Uninstall old versions of Microsoft Office from your computer and try to activate Microsoft Office 365 again. This works for a week and then the issue raises it’s head again. And it’s random users, not all users experience this in this environment.

I highly recommend NOT just disabling modern authentication using that registry entry because you will have all manner of headache with other Office365 applications. If you are sure that there are no connection issues, but your Office 365 is not detecting a new update (and you can’t see the "You’re up to date!" message), check the Office 365 update channel. Some of them allow users to get updates before the main release while others provide updates at a later time. The update channel used by Office 365 depends on your Office 365 subscription plan and on configuration. If after running the Remote Connectivity Analyzer Office 365 issues are not fixed, try using Microsoft Support and Recovery Assistant.
