Default email for replies

I recently set up a business email and am using the windows default email app to access it because I already use two emails and have a free account. I wanted to ensure that it is separate Every single time I try to reply using the business account on the windows app it defaults to replying with emclient and the FROM: email address. I’ve looked in the settings and eMClient isn’t set as the default but it refuses to allow other apps to process the reply. Is there a work around I can do other than buying a license and adding the business account? It is obviously really annoying because I’ve already sent emails out not realizing it with my personal account as the sender…its kind of irritating…

That is btw. one of my feature requests that was ignored - check “to” address and if account is not one that you’re using in most cases (or last time) for this recipient - display warning about it.
