A Microsoft file hosting and synchronization service.
For a Personal Vault sign-in loop on a laptop browser, use this sequence:
- Confirm the account type is correct. If the sign-in page shows messages like "Selected user account does not exist in tenant 'Microsoft Services'" or "cannot access the application '00000003-0000-0ff1-ce00-000000000000'", a work or school account is being used instead of the Microsoft personal account. Personal Vault for OneDrive home must be opened with the Microsoft personal account.
- Check whether the issue is browser sign-in state rather than Vault itself.
A known Microsoft sign-in loop workaround is:
- Go to https://login.live.com/
- Sign in with the Microsoft personal account
- Then open OneDrive again in a new tab and try Personal Vault
- On the laptop, make sure the Microsoft sign-in sites are not partially isolated by browser security settings.
For Microsoft sign-in loops, these sites should either all be outside the trusted sites list, or if organizational policy requires trusted sites, all of them should be included together:
-
microsoft.com -
support.microsoft.comand subdomains -
login.live.com -
login.microsoftonline.com
-
- If Personal Vault still will not open, test whether the Vault itself is current and synced:
- Unlock Personal Vault where possible
- Close any files stored in Personal Vault
- Wait for sync to complete If sync is stuck, the Vault may report that it is not up to date.
- If the laptop has OneDrive cached credential issues, clear the cached credentials on Mac:
- Open Keychain Access from Spotlight or Utilities
- Search for OneDrive
- Delete OneDrive Cached Credential
- Run OneDrive again
- If OneDrive sign-in still fails, check for network blocking. Microsoft notes that firewall, VPN configuration, or the internet provider can block OneDrive sign-in. If possible, temporarily test without VPN or by using a different network such as a mobile hotspot.
- If the issue is specific to BT broadband with BT Web Protect enabled, disable BT Web Protect in the BT account security settings, because it can block access to OneDrive.
- If none of the above resolves it, use Microsoft support from the OneDrive support path:
- For personal accounts, use Contact Microsoft Support
- On mobile, support can also be contacted from the OneDrive app by shaking the device
