Hi Scott.

I'm trying to figure out how to sort the crazy Outlook inbox by ReceivedTime ...

What are you seeing when you use this sort? I suspect that it is actually working because when you retrieve the items in the inbox, by default, they are sorted by ReceivedTime with the oldest message first. Did you try sorting them descending? This works for me:

oOutlook = CREATEOBJECT( 'Outlook.Application' )
oNameSpace = oOutlook.GetNamespace( 'MAPI' )
oInbox = oNameSpace.GetDefaultFolder( 6 )
oMessages = oInbox.Items
oMsg = oMessages.Item( 1 )
?oMsg.SenderName
oMessages.Sort( "[SenderName]" )
oMsg = oMessages.Item( 1 )
?oMsg.SenderName
oMessages.Sort( "[ReceivedTime]", .T. )
oMsg = oMessages.Item( 1 )
?oMsg.SenderName
?oMsg.body
