A Microsoft file hosting and synchronization service.
Hello Bud Tripp,
Thank you for posting on Microsoft Q&A forum
When you see the prompt to "setting up" Personal Vault on your new Android phone, it does not create a new vault. It simply establishes a secure, trusted connection between that specific device and the existing vault in your cloud storage.
So, you only need to finish setting up and it will connect you to your existing vault.
If you have any more questions, feel free to reply back to this post. I'll be happy to help.
