How to only store outlook.com mail locally

Hello,

Please can you help me.  I use Outlook 2019 classic client on my desktop pc with my outlook.com account.  It was using POP / SMTP to download all my mail to my local pc.

Now after September 16th when Modern Authentication was required this stopped working as expected.  I have connected my outlook 2019 up to outlook.com to overcome the POP / SMTP basic authentication but now it just syncronises my email to my pc.  The mail is still showing in outlook.com.  I wish to download my mail to my local pc and not store any in outlook.com is this possible?  and if so how do i do it please?

Many thanks.
