How to resolve 'OneDrive can't start Excel' error on Mac after updating?

When my Mac updated I am unable to access Excel. I had purchased the one time offer of Office Home & Business 2024. I now get an error message of OneDrive can't start. This only applies to Excel and not to any of the other Microsoft applications.

Disable Excel’s OneDrive/Autosave integration

This bypasses the failing cloud startup.

  1. Open Word (or PowerPoint)
  2. Go to Preferences → Save
  3. Turn OFF these options:
  4. ✔ AutoSave
  5. ✔ Save to OneDrive by default
  6. Quit Word
  7. Try opening Excel again

This alone fixes it for many users.

These misconceptions often arise when third-party products fail to function or meet user expectations.


This responsibility lies solely with the third party developer ( MS Windows ) to evaluate the performance of their products when used on an Apple Computer running the intended version of macOS.
