OneDrive change User Account

[Jesper Stein]

My question is, if I have a user, that changes from one company to another (still inside the global company and therefor still in the same Tenant) the user gets new UPN and new e-mail address, how do I give that user access to the same OneDrive the user had before the change?

It seems that OneDrive thinks its a new user and therefor creates a new OneDrive, that is not so good.

Here we are talking about two different things...if you change the UPN of your user, he will have a new fresh OneDrive and it's not clear to me what happens with the previous ODFB...if you only change the domain of the user, nothing is going to happen with the ODFB of the user
