Moving the office365 to a new account
I have a client that has no admin access to their office365. The I.T. company owns the account and has control over everything. They have parted ways and are hostile to each other.
The client owns the domain name and has access to change the mx records.
They want to create a new account in office365 with their own information, recreate all the mailboxes and transfer the email to the new account.
I know it would be easier to get admin access to the existing account but this isn't an option.
I was thinking I can download all their emails to pst files create the new account and setup the mx and spf records to get the mail flowing. Then copy the emails from pst to the new mailboxes.
My question is will outlook get confused as to which account it connects to? If I do this will their mailboxes try to connect to the other account which will still have the mx/spf records in them.
There will be two office365 accounts and they will have identical mx/spf records. I suppose I can try to contact Microsoft and see if they can deactivate the old one but I'm not sure they will without an admin account.

You won't be able to spin up another tenant with that same domain name. You can contact MS and see if you can take it over but that doesn't sound likely. Time to get the lawyers involved.
No. If they can prove ownership via the domain then they can takeover the tenant. They just need to contact Microsoft
How do I even contact them? Usually I log in to admin account and click help and they call me. Can I call them even if I'm not the owner of the account?
are you Microsoft partners? if yes there is a way to contact support from the Partners center.
No I'm not a partner, I'm an I. T. guy he hired to get control of his email or migrate to a new account.
Lol, the client is a lawyer.
