Hi Cort Johnson
Since you have already been referred to the Microsoft Data Protection team, you may need to allow some time for them to contact you. From what I’ve seen in similar situations, this team can be quite busy, so the callback may take around 3–10 business days. You can also keep an eye on your alternate email, including the junk/spam folder.
If the phone support route is not helpful, another workaround you can consider is creating a temporary Microsoft 365 Business trial tenant and submitting a support request from its Admin Center.
-Create a temporary Microsoft 365 tenant using a trial license: Go to Microsoft 365 Business Plans and Pricing and click Try for free to set up a temporary Microsoft 365 tenant with a trial license.
-Use this new account to sign in to the Microsoft 365 Admin Center and submit a support request on behalf of your primary (locked) account.
-Select the Help & support (headset) icon. If Support Assistant is enabled, turn it off > Type contact support in the search box > Select Contact support, then choose Phone or Email to submit your request.
(This method doesn't require you to use your new account for your business. Instead, it allows you to create a temporary global administrator account so you can submit a support request, as your original global administrator account is locked out due to issues with multi-factor authentication. The trial account is free for one month. Be sure to delete it after submitting your support request to avoid any automatic renewals or charges from Microsoft)
For further instructions, you can follow this guide: Get support - Microsoft 365 admin | Microsoft Learn.
In the request, simply explain that you created the temporary tenant only to contact support because you cannot access your original tenant, and ask for the case to be routed to the Data Protection team for MFA reset/account recovery.
Please note that this forum is a peer-to-peer community, so while members can share advice and experiences, only members do not have access to internal databases or the ability to escalate cases directly to Microsoft’s internal teams. Therefore, please kindly contact the Microsoft Support team for the most efficient help.
I hope this information helpful.
