Hi, guys.
I have noticed some of my sent PM didn't appear in the correct chronological order(even I press relevant "date" button) in the 'Sent items' box. If you scroll back in dates, apparently some newly replied pm would randomly shown up within earlier dates.
For example, if I want to check on a message I just sent, I may or may not find it in the 1st page of 'Sent items' but it may shown up on 3rd page.
I wonder does it have anything to do with the last reply I got from my correspondent?
