Is there way to clear address book cache on all lotus notes clients

Hi,

In our organization, we have assigned internet certificates (S/MIME) for some of our users. However, often they receive mails on their Internet address which are encrypted with Lotus Notes certificate and not with their smime certificate.

We think this is because of local cache of address book that some users have in their lotus notes client.

Is there any way to solve this problem? Can we clear the local address book cache from all the users automatically?

Subject: I use this in the Postopen event in the user’s mail database to ensure Recent Contacts is kept clear . . .

Dim contactsdb As New NotesDatabase(“”,“names.nsf”) Set recconview=contactsdb.GetView(“(Recent Contacts)”)

Set contactdoc=recconview.GetFirstDocument

Do While Not contactdoc Is Nothing

	Call contactdoc.Remove(False)

	Set contactdoc=recconview.GetFirstDocument

Loop
