After installing the most recent Windows update, things went south for some of the users, as some of their applications refused to work.
Error 80080300 after installing KB5003169
According to Microsoft, the May 11 cumulative update for Windows 10 is causing some abnormal behavior with some of the apps that we use on a daily basis. After installing KB5003169, users that are running Windows 10 1909 are unable to sign in to some of the Microsoft 365 desktop client apps. When trying to connect to Microsoft Teams, OneDrive for Business, or Microsoft Outlook, most of them are prompted by the error text 80080300, or “We ran into a problem. Reconnecting…”. As frustrating as it might be, this is not the first time that applications go haywire after a Windows 10 update, so rest assured that the solution is right around the corner.
How can I fix error 80080300?
Thankfully, the way to fix this issue is as simple as restarting your PC, because that’s all you have to do. Simply restart it again, even if your device already performed this action after installing the update. If this doesn’t work for you, Microsoft recommends a workaround for this issue that involves rolling back the update, while they are still investigating the root cause and coming up with an ideal way to deal with it. If you don’t want to go through this entire process and would rather just wait for a fix patch, you can still use the web or mobile versions for these apps, unaffected by this error.
