I tried to activate my Office 365 installation through signing in to my Microsoft account, but the login dialog closed itself before I could get to enter my password. The exact same issue was already described in https://answers.microsoft.com/en-us/msoffice/forum/all/unable-to-activate-office-365-apps-windows/7789bbe9-08e8-457b-b866-803570616d16.

    Solution

    The solution described at https://docs.microsoft.com/en-us/office365/troubleshoot/authentication/automatic-authentication-fails#resolution eventually worked for me.

    TL;DR

    Run the following command in PowerShell:

    if (-not (Get-AppxPackage Microsoft.Windows.CloudExperienceHost)) { Add-AppxPackage -Register "$env:windir\SystemApps\Microsoft.Windows.CloudExperienceHost_cw5n1h2txyewy\Appxmanifest.xml" -DisableDevelopmentMode -ForceApplicationShutdown } Get-AppxPackage Microsoft.Windows.CloudExperienceHost

    During my research I also came across https://docs.microsoft.com/en-us/office/troubleshoot/activation/reset-office-365-proplus-activation-state, which might be helpful for some people, too, but didn't work for me, unfortunately.
