On the new Mac, the problem is expired or corrupted OneDrive/Office credentials for the work account. Fully clearing those credentials and re‑linking OneDrive usually fixes the repeated “credentials have expired” and failed sign‑in loop.
Follow these steps on the new Mac in order:
- Clear OneDrive/Office credentials from Keychain
- Open Keychain Access:
- Press Command + Space to open Spotlight.
- Type
keychainand select Keychain Access. - If it does not appear, open Finder → Applications → Utilities → Keychain Access.
- Search for OneDrive credentials:
- In the top‑right search box, type
OneDrive.
- In the top‑right search box, type
- Delete cached OneDrive credentials:
- In the results, look for entries named OneDrive Cached Credential (and any similar OneDrive/Office cached credential entries related to the work account).
- Select OneDrive Cached Credential.
- Press the Delete key or right‑click → Delete and confirm.
[OneDrive/Office/MS]and click Delete References if such a keychain exists.
This removes the expired credentials that are blocking sign‑in.
- Re‑link OneDrive and sign in again
- Close all Office apps:
- Quit Word, Excel, PowerPoint, and OneDrive if they are open.
- Start OneDrive again:
- Press Command + Space, type OneDrive, and open it.
- Sign in with the work account:
- When OneDrive opens, sign in using the same work account that works on the other Mac.
- If OneDrive says a folder already exists, choose Use this folder to keep the existing OneDrive folder location.
- Let OneDrive sync:
- Wait until OneDrive shows that files are up to date (no sync errors). This ensures the account is correctly linked.
- Test in Word on the new Mac
- Open Word.
- Open a document stored in the work OneDrive.
- If Word prompts to sign in, use the same work account that was just set up in OneDrive.
- Confirm that saving works (no “credentials have expired” message). Try a small edit and save.
- If the issue continues: reinstall OneDrive
If clearing credentials and re‑signing in does not resolve it:
- Uninstall OneDrive from the new Mac.
- Download the latest OneDrive client for Mac from the official download link in the references below.
- Install it, sign in with the work account, and let it fully sync.
- Then open Word again and test opening/saving a OneDrive document.
Uninstalling/reinstalling OneDrive does not delete files stored in the cloud; they remain available on OneDrive.com.
These steps specifically address expired or corrupted OneDrive credentials on macOS, which matches the “credentials have expired” and failed sign‑in behavior seen only on the new Mac.
