Remove MSP Admin Access to Tenant

[VegasITGuy2424]

Hi All,

I am taking over IT responsibilites for a mid-size company.  Currently, we are dealing with a roque MSP who has admin credentials for everything including our M365 tenant. No internal employees of the company, including owner, have been provided admin rights.  

I should add that this MSP is a one-man shop, I seriously doubt he has any formal partner relationship with Microsoft, but I may be wrong about that.

My feeling is that he has not registered the tenant the correct way and ownership shows his name rather than the company, but I can't prove that.

due to conflicts, there is an eminent possibility that he will begin deleting accounts, removing licenses or otherwise interrupting business.

Is anyone aware of a method for contacting Microsoft to deal with these sorts of disputes?  without an admin account, I don't even have the option to raise a support case with them right now.

We may be in a tough situation given that we pay him directly for services, so the invoice and payments will probably be in his name.

any thoughts or suggestions are appreciated!

@VegasITGuy2424 I've forwarded your inquiry to some internal folks. I will let you know what I hear back.

We have dealt with this many times, sadly.
Open ticket with msft and provide proof you are the tenant owner.
Does your license bill come from msft or 3rd party. If 3rd party is other than MSP then contact them to regain admin rights.
In several cases the client had to start legal action against the MSP for ransoming the tenant. Now legal should clearly review the MSP contract as it may say he owns it. Non the less delete or ransoming does have legal actions in some states
