#Why Microsoft OTP Is Not Received Common Causes
When your Microsoft OTP doesnât arrive, the issue usually falls into three buckets: network or carrier problems, account security settings, or thirdâparty SMS filters. Understanding the root cause saves time whether itâs a delayed SMS, a blocked number, or an email going to spam.

Your Microsoft account may have authenticator app only as the default method, not SMS.

#Troubleshooting Microsoft Verification Code Not Received
Start with the basics: check your phoneâs signal, ensure SMS isnât blocked by a thirdâparty app, and verify that your Microsoft account has SMS enabled under twoâstep verification settings. Often, a simple restart of the phone or toggling airplane mode forces a fresh delivery.
Turn off WiâFi calling temporarily it can interfere with SMS routing.

#What to Do When the Microsoft SMS Verification Code Fails

Whitelist Microsoftâs domain in your email providerâs filter settings.
Forward a test email from Microsoft to check deliverability.
If you use Gmail, look under All Mail it might be archived.
As a fallback, set up SMS as an alternate method if email continues to fail.
