Dear Petros A
Thank you for reaching out to the Microsoft Q&A Community. I understand you're experiencing an issue with not receiving the verification code on your mobile phone, and I am happy to assist you with that.
The situation you've described can arise from a number of factors, may be temporary network problems to security-related delays. The message "That verification method isn't working right now. Please try another method" often appears when there's an issue with the delivery system or if the system flags the request for security reasons. The "try again in 24h" message is a security feature to prevent automated attempts to access your account. The delay in receiving the code, even after waiting, can also be attributed to carrier-specific issues or a temporary backlog in the verification system. Please kindly follow these steps to solve the problem :
1. Check Your Phone's Settings and Carrier Service
Before attempting to recover your account again, please ensure that your mobile phone is capable of receiving text messages.
Signal Strength: Make sure you have a strong mobile network signal.
SMS Blocking: Check if there are any settings on your phone or with your mobile carrier that may be blocking SMS messages from unknown or specific senders.
Storage: Ensure your phone's message inbox is not full.
2. Update Your Security Information
The most reliable way to prevent this issue in the future is to ensure your account security information is up-to-date and to add multiple verification methods.
Add Another Alias: Consider adding a secondary email alias to your account that you can use for recovery.
Authenticator App: Use the Microsoft Authenticator app for a more secure and reliable method of verification.
3. Use the Account Recovery Form
If you are consistently unable to receive the code on your phone, the Account Recovery Form is the official and most effective method to regain access to your account. This process bypasses the need for a real-time verification code and instead relies on you providing detailed information to prove your identity.
Access the Form: Go to Recover your account
Provide Information: Fill out the form with as much detail as possible. The more accurate information you provide, the higher the chance of successful recovery. This includes:
Previous passwords you've used.
Subject lines of recent emails you've sent.
Names of contacts in your email address book.
Any other information about your account usage that only you would know.
4. Contact Microsoft Support
If the above steps do not work, you can try to contact Microsoft support directly.
Contact Microsoft Support Directly:
Go to Contact - Microsoft Support: Contact - Microsoft Support
In the search box, type "account issues" and press Enter.
Scroll down and select the "Contact Support" or "Sign in to contact support" option. You can sign in using any other accessible email address you have.
For "Product and services", select Microsoft 365 and Office.
For "Category", select Manage my profile information.
You should then see the option to "Chat with a support agent in your web browser".
I hope these steps help you resolve the problem. If you require additional guidance, feel free to reply to this thread and I’ll be happy to assist you.
Warm Regards,
Alice
