Outlook Question

[DoubleDown]

I use Microsoft Outlook as my primary email program. I sort the inbox msgs by Date/Time Sent; with the most recent msg being displayed at the top of the list. I was playing with the settings recently and have managed to completely [censored] up the display settings somehow. The msgs still display in descending order based on when they were sent... BUT all new msgs that are retrieved from the network lack a timestamp attached to them until they are opened up in outlook by me. Therefore, all the new msgs go to the bottom of the list instead of the top of the list where all the recent msgs with recent timestamps are.

Can someone please help me figure out how to get my newest msgs to the top of the Inbox? TIA
