Seems like I spend an inordinate amount of my free time researching solutions for work, especially for Outlook.

Suppose you, like me, want to make Outlook 2007 stop grouping your messages by date. Here is how:

1. View —> Current View —> Define Views… “Custom View Organizer”
2. Modify button “Customize View: Messages”
3. Group By… button “Group By”
4. Uncheck “Automatically group according to arrangement” and leave “Group items by” as “(none)”
5. Ok, Ok, Close buttons

No more group by date for all folders (including newly created folders).
