.mobileconfig does not install email account

I have an email with a private domain, they provide a .mobileconfig file, I have already installed it on another mac. but after installing the profile on my mac there is no email account in the mail app, so i dug around and found it hasn't installed an internet account which it did do on my other mac. I have done all the basics like restarting the mac, deleting and reinstalling the .mobileconfig file and redownloading it, unfortunately nothing has worked so any help would be appreciated
