Can Microsoft access the contents of my OneDrive Personal Vault?


I found the article to be quite informative that addresses the question "Can Microsoft access my private files?" (Can Microsoft access all private data if a user installs Windows 10?), which includes my OneDrive files, but it didn’t specifically mention the special folder called Personal Vault. Does Microsoft have just as much capability of accessing the contents of my Personal Vault as it does all my other OneDrive files, or is Personal Vault an exception?
