Merge two Mailboxes into one Groupwise 12

Hi,

Thats my question:

I have two Mailboxes. For Example:

Mailbox A = John Wayne ( Department IT-1 LvL Support )
and
Mailbox B = Kobe Bryant ( Department IT- 2 Lvl Support )

These two Persons merge into one Department ( Department IT )

So i have created a Novell User and an empty Mailbox Department IT

Both have many Mails in their Mailboxes and their Archives.

Is it possible to merge these two Mailboxes with Groupwise 12 into one so that there is just the Department IT Mailbox with all the mails of both persons? Is maybe a Merge Tool availible or something?

Thanks for your help
