It's not wise to store the recovery key on flash drive, for example. That means anyone that steal my computer and my flash drive can easily decrypt my recovery key. That defeats the purpose of encrypting it in the first place.
So I tried to save my Bitlocker recovery key somewhere, and a nice place to put it is of course my Microsoft account.
Yet, when I try I get a message "Can't save to your Microsoft account":
How can I successfully save my Bitlocker key to my Microsoft account?
My problem is similar to what's discussed here at answer.microsoft.com.
