Question details
The user is unable to recover a newly created Microsoft 365 account because password reset verification calls are failing, likely due to registering a landline office number.

- Product
- Microsoft 365
- Device & OS
- not provided
- Scenario
- Attempting to reset the password and recover a newly created account using phone verification.
- Observed behavior
- Automated verification calls fail to go through, leaving the user locked out and waiting for a temporary password via an existing Microsoft support case.
Gather your existing Microsoft support case number and an alternative mobile number or email address that can receive verification codes directly.
Update Your Existing Microsoft Support Case
Provide Microsoft with an alternative verification method and clarify the issue with the registered landline to expedite your account recovery process.
When an account recovery involves a landline or a number equipped with an extension system, automated verification calls usually fail to route correctly. Updating your existing support ticket rather than opening a new one is the fastest way to resolve this block.
Find the confirmation email or ticket number for the existing Microsoft support case you originally opened for the account recovery request.
Reply to the Microsoft support email or update the ticket portal with a valid mobile number or alternative email address that can successfully receive SMS texts or direct verification calls.
Clearly state in your case notes that the original number registered to the Microsoft 365 account is a landline office number, which is causing the automated verification calls to fail.
If your case has been escalated to Microsoft's Data Protection team, simply monitor your newly provided contact methods. Do not create duplicate tickets, as this will reset your place in the queue.

Frequently Asked Questions
Why do Microsoft 365 verification calls fail on my office number?
Automated verification calls from Microsoft often fail if the registered number is a landline equipped with an extension system, IVR, or automated attendant that blocks the direct routing of the call.
How long does the Microsoft Data Protection team take to recover an account?
Resolution by the Data Protection team can take anywhere from a few days to several weeks, as they must perform stringent manual security checks to ensure the account is not being handed over to unauthorized users.
Should I open a new support ticket if Microsoft has not replied yet?
No, you should avoid opening duplicate support tickets. Creating multiple account recovery requests can confuse the automated system, reset your place in the support queue, and significantly delay the recovery process.
