Dear Michele Giammarini1
Thanks for choosing Microsoft Community.
Based on your description, I know the scenario you met. For this, this is a known issue that some users have faced. Here are a few things you can try:
- Wait and Retry: As the message suggests, wait for 24 hours and then try the validation process again. Sometimes, temporary issues can cause validation failures.
- Check Phone Number Format: Ensure that you are entering your phone number in the correct format, including the country code.
- Service Issues: There have been instances where service issues temporarily blocked certain countries from joining the program. These issues are usually resolved quickly.
- Multiple Attempts: If you have requested the code multiple times, make sure to wait for the code to arrive before requesting another one. Sometimes, the code might arrive with a delay.
If none of this can help, for this, to better help you, please be kindly to get our phone call support via : Global Customer Service phone numbers - Microsoft Support. The engineers there will help you solve this.
Your understanding and co-operation are highly appreciated.
Thanks for your precious time. Have a nice day.
Sincerely
Katherine
