When we enable BitLocker, the recovery key will be saved in:
- your Microsoft account
- a USB flash drive
- a file which need to be keep in another place
- a printout.
There is not an option to save recovery key in OneDrive directly.
So I think the bitlocker recovery key which generated by method 2 and 3 are correct key, can be used for unlock your encryption, the bitlocker recovery key in your OneDrive is an out-of-date key. You know, every time we enable bitlocker it will generate a new recovery key, the key in OneDrive should be previous encryption, is no longer valid.
You could manually save current BitLocker recovery key TXT file into your OneDrive.
From my experience, when I enable BitLocker, I usually save my recovery key into my Microsoft account and print it as a PDF, name it as current date then save in my OneDrive.
