Frequently Asked Questions
Why does Microsoft block tenant creation during OTP verification?
Microsoft employs strict automated security measures to prevent fraudulent account creation. If an IP address, phone number, or sign-up pattern triggers these security filters, the system automatically blocks the OTP step and requires manual identity verification.
Can I bypass the OTP verification when creating a Microsoft tenant?
No. The one-time password and identity verification steps are mandatory security protocols for registering new Microsoft 365 or Azure tenants. If your attempt is blocked, you must contact support to proceed.
How long does it take for Microsoft Support to unblock my tenant creation?
Resolution times vary depending on the support queue and the details requiring verification. Once you provide the necessary identity information over the phone, the agent can typically clear the block during the call or within 24 to 48 hours.
Are there other ways to resolve this if I cannot make a phone call?
If you cannot call the provided numbers, you can try raising a support ticket if you have access to another existing Microsoft account. However, direct phone support is generally the fastest and most highly recommended method for resolving business account creation blocks.
