How to Fix Microsoft 365 Correlation ID Error on Mac
Question details
The user encounters a Correlation ID error when attempting to open Microsoft 365 applications on a Mac.
- Product
- Microsoft 365
- Device & OS
- macOS
- Scenario
- Opening Microsoft 365 applications
- Observed behavior
- The application fails to open and displays a specific Correlation ID error (e.g., 1d7ef937-88af-4c81-bcdd-b2562c2eb40e).
Ensure you have your Microsoft account credentials handy, as you will need to sign back into your Microsoft 365 applications after performing these troubleshooting steps. Also, take note of whether this issue affects a single application or your entire Office suite.
Update Microsoft Office Applications
Outdated software can cause unexpected authentication errors. Updating to the latest version often resolves underlying communication bugs.
Microsoft frequently releases updates to patch authentication bugs and improve macOS compatibility. Checking for updates is the quickest first step to resolving sign-in correlation errors.
Launch an Office application on your Mac that is still accessible, such as Word or Excel. If none open, launch Microsoft AutoUpdate from your Applications folder.
In the top menu bar, click on 'Help' and select 'Check for Updates' from the dropdown menu.
Follow the on-screen prompts to download and install any available updates, then restart your Mac and try opening the application again.
Clear Office Cache and Remove License Files
Corrupted license files or container caches are the most common cause of correlation ID errors on Mac. Removing them forces a clean authentication.
Tired of Microsoft 365 Errors on Mac? Try WPS Office
If correlation ID errors and complex troubleshooting are disrupting your workflow, consider switching to WPS Office. It provides a lightweight, highly compatible, and free alternative to Microsoft 365 on macOS, allowing you to seamlessly create, edit, and manage your documents without subscription hassles.
- 1. Download and Install: Get WPS Office for Mac from the official website and complete the quick installation process.
- 2. Open Your Files: Drag and drop your existing Word, Excel, or PowerPoint files directly into WPS Office to continue working immediately.
Frequently Asked Questions
What does a Correlation ID error mean in Microsoft 365?
A correlation ID error is a unique diagnostic code generated by Microsoft servers when an authentication or connection process fails. It helps support teams trace the exact server-side issue, typically related to account sign-in or license verification on your Mac.
Will deleting the UBF8T346G9.Office folder delete my documents?
No, deleting this folder will not delete your saved Word, Excel, or PowerPoint documents. However, it does store local templates, Outlook profiles, and application settings. If you use Outlook on your Mac, you should back up your data before moving this folder to the Trash.
Why do I need to use the Microsoft License Removal tool?
The tool ensures that all hidden and corrupted activation files are completely stripped from your macOS system keychain. Doing this manually is difficult, and using the tool ensures a clean slate so you can sign in successfully without triggering the previous correlation ID error.
