One of the great features in Office Outlook 2010 is the social feature, aka the People Pane. While the People Pane does look very promising (IE: Tracks Social Activities from RSS Feeds, Twitter <enter social network here>, Recent Conversations, Status updates, Calendar Items, Attachments etc… from the selected contact), being that the product is in Beta and not fully working it really does take up A LOT of room especially if you’ve enabled the preview pane. With that in mind, let’s get rid of it!
Who knows, perhaps when a few of the social networking plug-ins become available for Outlook 2010 the people pane will be more useful.
Until then, if minimizing the People Pane isn’t good enough (just Click the Down arrow on the right-side of it) you always have the option to disable it completely.

Wow what a space hog, lets disable it!
How To Remove The Annoying People Pane From Outlook 2010 Emails
1. Click the View tab, then Click the People Pane button. From the People Pane menu, Click the Off option.

Viola, that was a simple solution and one more annoyance marked off the list! We can always come back later and re-enable it if we decide to use the Outlook 2010 People Pane.

Yeah I'm kinda torn on the People Pane myself. I like the extra info regarding emails and calendar items from the user but… it does take up a lot of room.
Personally I keep it minimized.
What about the preview pane? Do you keep it on the bottom, right or disabled?
I don't mind it. It sits minimized on my preview pane, which is on the right side.
I have a 23″ monitor, so I have a lot of real estate to use up.
At this point, I haven't had a need for the people pane yet as I do not work in a big office environment anymore where I think is where that would come in handy most of the time. Especially with Exchange, people pictures and information would probably be auto-populated.
You know, for whatever reason with Outlook 2007 I always kept the preview pane on the bottom but now that after using Outlook 2010 for the last week I tried to keep it on the right side and I'm actually getting used to it and…. I like it.
People Pane, I think its nice. LIke Izzmo said, I do work in a large office so it's very handing to have the other details. The Social aspects of it are still limited (Sharepoint only) but I personally leave it open.
Still, good article groovyDexter!

Yeah I'm in a corp environment so the exchange/outlook is linked to Sharepoint so we get all ppl's pics in there. Still, until more social networks are added I keep it minimized. takes up WAY to much real estate.
Ya know, I tried the right side but i just don't like it that not all my columns show up…. bottom for me… I never actually OPEN email, preview pane for the win.
