There are a couple sources of information out there on how to do this:
- petroleumjelliffe.com describes how to "Make Outlook Work Like GMail" however it does not explain how to get sent messages to go into the inbox and not be marked as read (this is explained in the comments, however)
- richardgoodwin.com explains how to "Sort your mail in Outlook" which makes it look a bit more like GMail except he sorts by date rather than by Conversation Index (which is better).
Here's how to do it all (at least for Outlook 2003), all documented for you here in one place:
The first thing you need to do is make messages you send get put in the Inbox. An additional thing you need to do is make them get marked as read (otherwise you'll always have tons of un-read messages from yourself in your inbox).[img_assist|nid=277|title=Outlook Gmail Rules and Filters|desc=This is what my "Rules and Alerts" look after after adding a "CC send messages to inbox" rule and a "Mark messages from self as read" rule.|link=none|align=center|width=435|height=335]
The next thing you need to do is make your e-mails show up in something that somewhat resembles GMails conversations. I set "Group By..." to "Conversation (ascending) and "Sort..." to Conversation (index).[img_assist|nid=278|title=Outlook Gmail Customized View Options|desc=This is what my customized view options look like after grouping by conversation and sorting by conversation index.|link=none|align=center|width=477|height=326]
Now your inbox should look a lot nicer now and finally, click on the column "Newest on top" to have them sorted by date properly and your Inbox should look as shown in the image.[img_assist|nid=279|title=Outlook Gmail Final Result|desc=This is what my inbox looks like|link=none|align=center|width=496|height=599]
