Partner lockout of Microsoft 365 tenant – looking for advice on next steps

Ermserg​ ,

I have no idea... if I understand you correctly: you're a CUSTOMER, not an MS PARTNER -- but you have an association WITH a Partner, and now that partner has locked you (the customer) out of your own Tenant? Is that right?

That seems shady to me, and not something I could see a legit MSP/CSP/MSSP doing (even if they wrote into that into their contract language, around missed invoices/bills). Essentially they have "stolen" or "hijacked" your Tenant and are holding it "hostage".

A recent /r/msp post implies calling the "data protection team at 18006427676" might help (even if that is only for Partners maybe they would know what to do when a Partner goes rogue?).

There's definitely a spot in the O365 portal for each Tenant where you can view GDAP and Partner registrations. But of course you need to get in there and be a Global Admin to do that. But if they are locking you out they probably also have their own Global Admin account, maybe multiple - meaning they can undo whatever you do if they're faster.

So you need to: A) find a new MS Partner, B) they or you need to contact MS re: restoring access to your Tenant, and C) they need to audit and remediate any possible security issues and lock the original Partner out.

Dealing with any unpaid invoices would be between you and the original Partner, but shouldn't involve your Tenant (even if the unpaid Invoice was for O365 related licenses).

If they continue to thwart you perhaps the Police could be involved? But I have to think Microsoft has a way to seize control of the Tenant and return it to its rightful owner - but that would be a JillArmourMicrosoft​  question I think (hope).
