M365 only admin locked out MFA error 53003
I am learning this the hard way....so here it goes. Currently I am locked out of as the only admin on the tenant with error 53003. I was updating some Microsoft MFA default policy settings in Entra and mistakenly deleted the admin user from the exclusions list, and got locked out. Thankfully I have another tenant, not as big the one locked out. Initiated several support tickets for which everyone calls, and despite of subline mentioning the issue says that they have to assign this ticket to Entra. Then the ticket gets updated and noone has been assigned every since. I have initiated severity A support tickets from Azure portal but no one has called in last 24 hours to help. We area business with Business Premium licenses with over 20 users, and now completely locked out. I have looked almost everywhere online. There is no phone number that takes you to a support agent - PLEASE HELP........
I need to speak to a person at Microsoft
Firstly, I don't know if this is the correct place to ask, if not, I apologise, and would be greratful if I could be directed to the correct medium. So..... *** I am writing this on behalf of someone else *** His account has been locked after he had been hacked and infected with a virus, and Microsoft will not unlock it. However, they have decided (today) to take his money for his 365 subscription, that he can't use, and doesn't want. When looking for a way to cancel it, the answer is log-in to his account and cancel it himself. BUT, he can't log in because the account is locked. He has tried looking for a phone number to speak to someone, but cannot find any. He has tried looking for a Live Chat, but, (if it exists) it is only available after he logs in. He just wants to cancel the subscription, and get a refund. Can someone please give me a contact number - preferably in the UK, but any English speaking representitive, in any countrty will do. Thanks,
Partner lockout of Microsoft 365 tenant – looking for advice on next steps
Hello all, I’d appreciate some guidance from the community on a serious situation we are facing. On 12 September 2025, our Microsoft partner unilaterally locked us out of our Microsoft 365 tenant. They retained exclusive Global Administrator / Partner Delegated Admin rights, which means: All staff and directors are unable to access email, Teams, SharePoint/OneDrive, or even log into their Azure AD-authenticated workstations. Our corporate and staff personal data is now inaccessible to us as the controller. Access restoration has been explicitly conditioned on payment of a disputed invoice (not related to Microsoft licence pass-through). This raises several concerns: Operational: we are effectively paralysed. Security/IP: the partner still has exclusive access to proprietary source code and other confidential business data. Compliance: we cannot meet our GDPR/UK DPA obligations on availability of personal data while locked out. We contacted Microsoft Business Conduct on Friday evening with full details of the incident, but so far no human response has been received to those emails. Questions for the community From a Microsoft tenancy perspective – what’s the fastest/most effective way to remove a partner’s delegated admin access if they refuse to release it voluntarily? Has anyone experienced or seen a similar scenario where access was conditioned on disputed payments? Are there formal Microsoft Partner Code of Conduct provisions that directly address this type of misuse of delegated admin rights? Any practical lessons on balancing the technical fix (regaining control of the tenant) with the legal approach (injunction, regulatory notifications)? My focus is on regaining secure access, protecting data/IP, and ensuring compliance. Any experience, insight, or links to Microsoft policy/resources would be greatly appreciated.
Unable to whitelist quarantined emails
We have an email that is being constantly quarantined from a webform. The email comes from the email of the web form server, but is spoofing an internal address in our tenant by design. The email keeps getting blocked, and nothing we've tried as far as transport rules, whitelist additions, etc has been able to discernably affect this. There is a option to create a tenant allow list entry but the maximum duration is 45 days. We need a way to reliably whitelist an email indefinitely.
Adding Outlook add-ins and permissions
Wonderoig if someone can answer a question for me. I'll use the process in this link as context https://help.draftable.com/hc/en-us/articles/46382047949977-Configuring-Redline-in-Email-Outlook-with-Draftable In short when adding an Outlook Addin and selecting a group to assign the add-in too and the accepting the permission requests does this: Apply the permissions to ONLY those nominated users' mailboxes; or Applies the permissions to ALL mailboxes and applies "security" by limiting the users who can see the add-in I assume it does one of the two. Any ideas?Not able to logon office 365 account or change it
If I want to logon to my Office 365 account I have to enter my emailaddress. Its is an @.onmicrosoft.com account. Entering password is ok, but then I am have to verify my phone number.

I already contacted helpdesk but they cannot solve this problem. I have a bussniess account and I need some help about this.
