You can do this by integrating your applet with the ‘On ItemReplyOpenItem’ event associated with the GroupWise application (not email). Your applet need to look at the first parameter associated with this command, as it tells you what type of reply the user is attempting. The possible values are:
All = 7
AllPrivate = 39
Sender = 1
SenderPrivate = 33
Discussion = 16
DiscussionNNTP = 144
DiscussionORIG = 256
If the value was 7 (All) you would then cancel the command. Here’s some sample code:
Sub Main(Client, GWEvent) if EventParams.Item(0).Value = 7 then ' 7 = Reply to all MsgBox "You cannot reply to all." Groupwise.CancelGroupWiseEvent = true end if End Sub

I hope this helps.
