Using the macro in "ThisOutlookSession" to have my assign category box automatically open when sending new mail. But......It won't work when replying to mail. Any experts have a solution. Outlook 2016.

Private Sub Application_ItemSend(ByVal Item As Object, Cancel As Boolean)
If TypeOf Item Is Outlook.MailItem And Len(Item.Categories) = 0 Then
Set Item = Application.ActiveInspector.CurrentItem
End If
End Sub

you don't need the following line - ByVal Item As Object, Cancel As Boolean sets the item.
Set Item = Application.ActiveInspector.CurrentItem

i removed the set item line and it worked for both new and replies... but if it still fails, instead of Len(Item.Categories) = 0 , try item.categories =""

also, note that when you set the category before sending, the category may visible to the recipient (if they use outlook) and in the message header: Keywords: Blue category.

if you definitely don't want to share the categories with the recipients, you can either use an itemadd macro that watches the sent folder and brings up the dialog after its sent or see if Sending Categories on Email Messages works for you.
