How to Fix Microsoft 365 Repeated Repair Now and Activation Problems
Question details
The user needs to resolve an issue where Microsoft 365 applications remain unlicensed, crash, and repeatedly display 'Repair Now' messages after a Windows reinstall.
- Product
- Microsoft 365
- Device & OS
- Windows
- Scenario
- Attempting to activate Microsoft 365 applications after reinstalling Windows on a new SSD.
- Observed behavior
- Microsoft 365 applications remain unlicensed despite being logged into the correct account. Office reinstallation fails, 'Repair Now' messages appear continuously, the Support and Recovery tool fails to load, and the applications crash.
Locate your Microsoft account login credentials and ensure you are signed in as an administrator on Windows to modify application settings.
Run a Microsoft 365 Online Repair
Use the built-in Windows repair tool to fix corrupted Office files causing the 'Repair Now' loop and activation failures.
Running an Online Repair downloads and replaces any missing or corrupted files in your Microsoft 365 installation. This is the most effective way to resolve repeated crash messages.
Ensure all Microsoft Office applications such as Word, Excel, and Outlook are completely closed.
Click the Start menu and navigate to Windows Settings, or open the traditional Control Panel.
Go to Installed Apps (or Programs and Features), scroll down to find 'Microsoft 365', click the three dots or right-click, and select 'Modify' or 'Change'.
Choose the 'Online Repair' option in the prompt window and follow the on-screen instructions to complete the download and repair process.
Verify Activation Error and Update License
Force Office to fetch your updated license credentials to resolve the unlicensed status directly from within an app.
Clear Identity Cache and Reinstall Offline
Clear old authentication caches and perform a clean reinstallation using an offline package if standard repairs fail.

Frequently Asked Questions
Why does Microsoft 365 repeatedly ask me to 'Repair Now'?
This loop usually happens when core Office files are corrupted or when there are conflicts with Windows background services after an OS reinstallation. Running an Online Repair typically downloads fresh files to replace the damaged ones.
What does Microsoft Office activation error code 29 mean?
Error code 29 indicates a problem with the authentication tokens on your device. Clearing the OneAuth and IdentityCache folders or removing the old Identity key in the Windows registry can resolve this token mismatch.
How do I fix the Support and Recovery tool not loading?
If the Support and Recovery tool fails to open, your Windows .NET framework or system files might be incomplete or corrupted. Try running Windows Update to ensure your system components are current, or bypass the tool by reinstalling Office from an offline package.
Will reinstalling Microsoft 365 delete my documents?
No, uninstalling and reinstalling Microsoft 365 only removes the application software. Your Word documents, Excel spreadsheets, and files stored locally or on OneDrive will remain entirely safe.
