where is your mail server? There is no 2-factor auth between servers, but rather DKIM/SPF (which is called DMARC), so could be your server is either not viewed as trust worthy or it is rejecting the mails for some reason.
In any case, I use Outlook for the professional work. It is impossible to have a comfortable way of working with those MS oriented companies. They will always find a way to screw you and you spent hours looking for solutions that do not exist. Especially as no government or authority is supporting you.
I think some mail clients (newer KMail and whatever is the follower of Evolution) handle Outlook with 2-factor auth. I tried them with google, not with MS, because I do not want to mess up the business accounts and cause issues there.
