Sending, receiving, and organizing email in Outlook.com
Hi there! My name is Ben a fellow member here in the community.
It is possible that the accounts you have from the previous device has not been transferred properly which is why it is not sending the code. If you still have access to the old device, you can try the following steps:
- Open the Microsoft Authenticator app on the old phone.
- Try logging into your Outlook account again.
- Approve the sign-in from the old phone.
- Once logged in, go to your Microsoft account security page
- Click “Add sign-in method” → choose Authenticator App, then scan the QR code on your new phone.
You can also follow the guide from the Microsoft support page to properly transfer your accounts from one device to another.
Don't hesitate to post back if you have other questions and we'll try our best to help.
