permanently delete email on my Android phone but mot on pc outlook

I have IMAP email on my android phone and on my PC. I want to be able to delete my email from my Samsung Email on my phone but not have it delete in my outlook on my computer. I used to be able to view my phone emails and delete them once read so that I only get new emails on my phone. When I logged into my outlook on my computer all those emails I deleted on my phone appeared in my pc outlook email which is indeed what I want. If I delete on my computer they would delete on my phone but not vise versa. Ever since I purchased a new PC and installed windows 11 and outlook on it, I no longer am able to do this. I am not able to see any setting on my pc outlook or on my samsung email about leaving an email on the server.
