Tried OneDrive Personal Vault & didn’t go well, curious how others found it.
Enabled OneDrive Personal vault and moved some data (which was already on OneDrive in ‘normal folders’) into it. Looked ok on-line, but my Laptop got all sorts of sync errors and rebooting randomly either:
1) Allowed no access to Personal Vault at all (in explorer or app) or did not offer ability to unlock. The red “Unlock your vault” panel was in the OneDrive flyout menu but did not respond when you clicked on it.
2) If could unlock PV OneDrive still showed “unlock PV to sync” errors, when it was already unlocked
3) Accessing local PV folders locked up File Explorer until the machine was rebooted, go to 1) or 2) and repeat
The other problem is it seems PV access is totally dependent on cloud connection to unlock even when the Vault is on your local machine. I would have those items in a ““Always keep on this device” folder for off-line access. The sort of things I would consider putting in it are those I need to be able to access (travel, medical documents etc) quickly, if need them at all.
In the end I moved all the data back out again and abandoned it.
