Unknown account attached to my number

Question

Hello,

I used the Microsoft username recovery tool with my phone number and it shows three Microsoft accounts associated with it. I recognize one of the accounts, but the other two are not mine and I do not recognize them.

For privacy reasons the tool only shows the usernames partially with asterisks, so I cannot identify them. I would like my phone number to be removed from those unknown accounts.

Please help me verify whether those accounts belong to me and remove my phone number from them if they do not.
