Samsung does not comply with current security standards for encryption so natively won't be able to use 365.
If your IT folks are very talented you can see if they can create a relay that you can use. I have yet to be able to convince someone to do it.
Here is a link to the MS article:
https://learn.microsoft.com/en-us/e...-email-using-microsoft-365-or-office-365

There are a couple youtube videos too, but I haven't tried them yet.
