Microsoft account signin does not work because of crash in cloud experience host

Question

My Office365 installation suddenly started reporting problem with my account. I tried to sign in as instructed but I'm unable to do so as instead of login window I see a blank rectangle which closes after a short delay. After several attempts to sign in the Office suite kicked me out and demands activation which I'm unable to do as I'm unable to sign in.

I'm signed in with the same account into Windows 11 on the same computer which works just fine. The same account also works on a separate computer as well as via web (i.e. https://onedrive.live.com/)

The problem has escalated and now I'm unable to sign in into any Microsoft service on this computer as the sign in dialog closes. In event viewer there is a crash in CloudExperienceHost.

I've tried to run commands from https://learn.microsoft.com/en-us/answers/questions/4250264/cant-login-to-microsoft-account-because-of-cloud-e?orderby=oldest&page=1&forum=windows-all&referrer=answers#answers without any improvement

I've also tried to re-install package with "Get-AppxPackage Microsoft.Windows.CloudExperienceHost | Reset-AppxPackage"

Answer 2

Hello, Samuli-Petrus Korhonen

Welcome to Microsoft Q&A

Thank you for your feedback. I understand that you are having trouble logging into Microsoft services. Here are some troubleshooting solutions:

1. Create a new local account.

Search for CMD in the search bar, select Run as administrator, and enter the following commands in order:

net user USERNAME PASSWORD /add

After the command is successfully executed, enter the following command:

net localgroup administrators USERNAME /add

Note: Replace USERNAME and PASSWORD with the account name and password of your choice. If you do not need a password, you can leave PASSWORD blank.

2. Try using Update Repair

Open Settings, System, Recovery, and select Use Update Repair.

If none of the above methods work, we recommend reinstalling Windows using a USB installation medium. Before doing so, please back up your important data.
