Security code linked to landline phone

Question

How do I bypass the security code to be sent to a landline phone? Someone logged in last month to my outlook business account online & changed the security code info (mainly phone number) to their number. I can't undo this as a code can't be texted to landline to verify it's me. The new number is not effective until Nov 7th. Do I have to wait until then to change that number to my cell number that can receive a security code?

Hi @Marylou

Based on your description, it seems that you may need to wait until that date to update the phone number to your phone.
