How do I get that nice inline-quote indicator in Outlook 2010 when replying to emails?

Outlook 2010 (beta). I like responding to email inline-style, where there is an indicator (typically a gray vertical bar, |) denoting the quoted content.

Not sure if I can attach an image, but will give text example:

This is some email content.

|  This is a quote from the original email

This is my response to that quote

| |  This denotes a nested quote from a previous message

And another inline response.

I just got an email from someone who replied inline with this same style, but I can't for the life of me find what format option in the Ribbon I need to do the same.

I know I can go through and do this manually with plain-text emails, but the email I am responding to accomplished this with HTML style message, and I would have to remove the formatting and then re-apply the quote style with plain-text markings.

Suggestions?
