As soon as was possible, I left Entourage in favor of Outlook 2011 Mac. I'm using Exchange 2010.
I seem to recall being able to create custom "Smart Folders" when I used Outlook on Windows, but can't seem to find a way to do it in Outlook 2011 on Mac. The closest I've seen was to use Filters on a folder, but that doesn't seem to include sub-folders, and I can't find a way to save it to come back to later.
What I would ultimately like is a single view that shows me anything that is flagged or unread, from any folder. I use server-side rules extensively to sort mail into different folders, so aggregating across all folders is important.
I accomplished this in Entourage by creating one saved search that showed flagged items from any folder, another that showed unread items from any folder, and then a third (which I would use as my primary view) that aggregated the contents of these other two custom views.
Anyone have any suggestions, or am I missing something obvious?
