no, that's not it.

this outlook button can only work if 'sign in options' is set to 'Microsoft apps can sign me in' at Settings / Accounts / Email & accounts (see pic related, both of those icons are myself)

I use a local account with a Microsoft account signed in under 'Email & accounts' for things like Xbox services. I have 'sign in options' set to 'All apps need to ask me to use this account', but knowing that a 'lite' Outlook client is somewhere still irks me.

interestingly, after messing with it, I've found that the 'send' features don't even seem to work at all. If I click Outlook at the bottom, I can input whatever contact I want, but it doesn't send to the recipient. It only shows up in my 'Sent' folder if I view my account online. So it doesn't even work, but that could just be an issue with my account.

If it failed to communicate with Outlook at all, I wouldn't be bothered, but since it still has the ability to send files to a server from Windows itself, I want it gone.

Task Manager seems to indicate that it's a function of the Windows Shell Experience Host, but that's all I can surmise.
