Windows 10 cumulative update causes Microsoft 365 app to fail to log in

Earlier we mentioned that Microsoft cumulative update has caused unexpected creaking or other noises in Windows 10 systems equipped with Dolby audio devices.

But it seems that the problems caused by these cumulative updates are not limited to audio issues. According to user feedback, Microsoft has confirmed that there are other problems with these cumulative updates.

This problem actually affects more office users, because an unknown error affects a large number of users logging into Microsoft 365 series office software components.

Affected include OneDrive, Outlook and Microsoft Teams, etc. When users try to log in, the 80080300 error code will pop up.

Office 365 Home Subscription Edition

KB5003169 cumulative update was released for Windows 10 v1909, and some users who still use this version are unable to log in after installing the update.

After user feedback and the media reports, Microsoft confirmed the existence of the problem after investigation. For now, Microsoft has not provided an exact and effective temporary solution.

Specifically, when the user logs in to these office software components, it will prompt us that we have encountered a problem and are reconnecting, and the 80080300 error code will also appear.

Microsoft said that most users may restart the computer again to resume normal login, but if they still cannot log in, they can only use the web version to replace it temporarily.

It is very embarrassing that KB5003169 is the last cumulative update of Windows 10 v1909. This version of Home Edition, Professional Edition, etc. has ended to support.

The versions that still provide support include Enterprise Edition, Enterprise Education Edition, and IoT Edition. Normally, Microsoft will not provide cumulative updates after the support is stopped.

So although Microsoft promised that it will fix this issue in the future, it is unknown whether the cumulative update released next month will cover home, professional, and workstations.

If Microsoft does not provide it, then users will either use the web version to replace it in the future or upgrade to a subsequent new version in order to be able to completely solve the problem.

Of course, we here also reminds everyone that Windows 10 v1909 version has ended support, based on security considerations, users should upgrade to the new version as soon as possible.
