How to classify the emails by month in Outlook?

If there are lots of emails in your Inbox, to make the mailbox look neat and well-organized, you can store or archive them into different folders based on the specific month of the emails’ received time as below screenshot shown. Normally, you can create the folders manually and then move them one by one. Obviously, this approach will be time-consuming and troublesome. In this article, I will talk about a VBA code for solving this task quickly and easily.

  DoEvents
  If xCurFolder.Items.Item(I).Class = olMail Then
    Set xMail = xCurFolder.Items.Item(I)
    xYear = Year(xMail.ReceivedTime)
    xMonth = Month(xMail.ReceivedTime)
    Set xMoveFolder = Nothing
    Set xMoveFolder = xCurFolder.Folders(xYear & "." & xMonth)
    If xMoveFolder Is Nothing Then
      Set xMoveFolder = xCurFolder.Folders.Add(xYear & "." & xMonth)
    End If
    xMail.Move xMoveFolder
  End If
Next
Set xMoveFolder = Nothing
Set xCurFolder = Nothing
