Configuration of outlook

I have changed ISP from one.com to simply.com and is trying to adapt outlook config. (I have outlook from Micosoft 365).

If I click on File->Account Setting ->Acount Settings and in the window click on repair I got this pictures for inc

As you can see they still point at my previous ISP. Any repair does not change this.

But, if I click on File->Account Settings-> Servers I got these windows:

Here the new ISP is correctly configured.

The question I have is why is the File->Account Settings->Account Settings->Repair not reflecting this change and shows the correct ISP?

My email is fully working anyhow.
