Hello,
Do you have any other Security Contact methods available to Verify Your Identity? And do you still have access to the old email address?
If you tried to sign in and Microsoft sends a verification code to an old email address you still have access to, you can visit the Security Settings page of your Microsoft account here to replace it.

- Sign in to an Old recovery email address to view the Verification code.
- Enter the code to verify your identity and sign in.
However, if you don't have access to the old recovery email address, you will need to replace your security information. That is, select 'I don't have any of these' on the screen and follow the prompts to replace it.
Note:
If you remove all of your previous security Information and replace it with something new, your account will be put into a restricted state for 30 days.
