I am trying to create a custom search folder in outlook 2010. I am using the "advanced" tab in the "search folder criteria" dialog. One of the criteria I need is the read/unread status of an message. But the "field" dropdown does not contain a field corresponding to read/unread status (see screen shot below).
This is odd because the read/unread status is available in the "More Choices" tab, but seemingly not in the "advanced" tab.
How do I create an advanced search folder criteria which incorporates the read/unread status of a message?
