Few days back I created a zoho email for domains account for my company. At that time I entered mobile number of my senior but at that time he was not available, so I couldn't verify that mobile number.

Now when I try to create new email for my domain it says this is already created and attached with the mobile number.

When I try to reset password and enter this mobile number, it says this mobile number is not verified yet.

Please let me know how can I verify the mobile number and get started with Zoho Mail for my domain.
