If you had the personal vault setup and working before, and it disapeared after an update or when you re-synched OneDrive, here is how you can bring it back:

1. Go to OneDrive synched folder.
2. Create a new shortcut
3. Paste the following as shortcut location: odopen://unlockVault/?accounttype=personal
4. Rename to 'Personal Vault - Custom'
5. Save

This new shortcut can now be used to access Personal Vault.
