In "quoting features" please turn off "indent replies" and enable "horizontal line".
That should be quite close to Outlook for Windows.
Now please note that we don't make claims anywhere that this will produce "quote headers" that are *exactly* same as in Outlook.
Close - yes.
Exactly - no.
In particular - different Outlook versions have subtly different "quote header" formatting, also between Outlook for Windows vs. Outlook for Mac (to the best of my knowledge, I don't own a Mac).
