How to Fix the Repair Now Error in Outlook, PowerPoint, and Teams
Question details
Users are experiencing repeated crashes in Microsoft 365 applications, prompting a 'Repair now' message that fails to resolve the underlying issue.
- Product
- Microsoft 365
- Device & OS
- Windows
- Scenario
- Launching or attempting to use Microsoft 365 applications such as Outlook, PowerPoint, or Teams.
- Observed behavior
- The application displays a dialog stating it encountered a problem and must close. Clicking 'Repair now' does not fix the issue, and error code 30015-11 (3221356598) may appear during the repair process.
Ensure you have administrative privileges on your Windows computer, as you will need to access the Control Panel and temporarily modify system security settings.
Perform a Manual Online Repair via Control Panel
Bypassing the failing in-app 'Repair now' button and running an Online Repair directly from the Windows Control Panel often resolves corrupted installation files.
The built-in 'Repair now' button often attempts a superficial quick fix that cannot repair heavily corrupted Office files. An Online Repair is more thorough because it connects to Microsoft's servers to download and replace damaged components.
Click the Start menu, type 'Control Panel', and press Enter. Navigate to 'Programs' and select 'Programs and Features'.
Scroll through the list of installed applications until you find your Microsoft Office or Microsoft 365 product.
Right-click the Microsoft Office product and select 'Change'. When prompted, choose 'Online Repair' and click the 'Repair' button to begin.
Temporarily Disable Security Software
Strict firewall, proxy, or antivirus settings might block the Office repair process, resulting in error code 30015-11.
Completely Uninstall and Reinstall Office
If repairs continue to fail, completely removing the corrupted Office installation and reinstalling a fresh copy is the most effective solution.

Frequently Asked Questions
What does error code 30015-11 mean in Microsoft 365?
Error code 30015-11 (3221356598) typically indicates that a background process, strict antivirus software, or a severely corrupted installation file is preventing Microsoft Office from successfully downloading and applying an update or completing an Online Repair.
Is there a difference between Quick Repair and Online Repair?
Yes. Quick Repair attempts to fix minor issues locally without requiring an internet connection. Online Repair is much more comprehensive; it takes longer and requires internet access, as it downloads and replaces all missing or corrupted installation files from Microsoft's servers.
Will running an Online Repair or reinstalling Office delete my personal files?
No, running an Online Repair or entirely reinstalling Microsoft 365 only affects the application files. Your personal documents, spreadsheets, and presentations saved locally or on OneDrive will remain completely untouched.
