Sorting Outlook emails

[StephenUK]

I'm hoping this is a simple question.

I have just imported some Outlook emails. (Most often I leave them in Outlook, but these ones I want in UR).

They have come in flawlessly, and the subject matters appears in the explorer bar, which is what I would want.

However, it would be nice also to be able to sort them in date order or by sender. I see that these fields have been imported as well and are shown in the header above the text of the email.

Is there any easy way to sort on those fields?
