What you need to know
- The latest cumulative update for Windows 10 version 1909 causes issues for Microsoft Teams, Outlook, and OneDrive for Business.
- The issues appear to affect a small subset of people's systems.
- Microsoft suggests rebooting your system as a workaround as it investigates the issue.
Microsoft Teams, Outlook, and OneDrive for Business run into issues following the latest update to Windows 10 version 1909. The KB5003169 cumulative update, which rolled out last week, appears to be the cause of the problems. The issues only appear for a small percentage of users, according to Microsoft.
Those that are affected by the issue will see a message that states, "We ran into a problem. Reconnecting..." or something similar. The message also has a button to restart the app. The error code for the message is 800800300.
Microsoft sent out a message through Microsoft 365 advisory regarding the issue (via Bleeping Computer):
The temporary fix for the issue is to restart your PC. Alternatively, Microsoft suggests that you use the web versions of Teams, OneDrive for Business, and Outlook while it investigates the issue. Using a web version of a service won't deliver the same experience, but it will allow people to access the popular Microsoft services until a more permanent solution is found.
Windows 10 version 1909 is now officially out of support for standard users, though it's probably safe to assume that Microsoft will find a way to have its most popular services work on it.
