Having set the reference to the Outlook Object Library, you can make use of
any of the methods included in that library.  Included in them are methods
to CC and BCC.  You will need to determine how you want to provide the email
addresses for the cc recipients.  You could have them included in the
catalog or directory merge document and grab them from there in the same way
that the email address of the addressee is obtained from that file, or you
could use an input box to enter it, or you can hardcode it into the macro.

The following modified section of the code shows how it would be done if it
is hardcoded:

   With oItem
       .Subject = mysubject
       .Body = ActiveDocument.Content
       Set Datarange = Maillist.Tables(1).Cell(Counter, 1).Range
       Datarange.End = Datarange.End - 1
       .To = Datarange
       .CC = "someoneelse@somewhere.com"
       For i = 2 To Maillist.Tables(1).Columns.Count
           Set Datarange = Maillist.Tables(1).Cell(Counter, i).Range
           Datarange.End = Datarange.End - 1
           .Attachments.Add Trim(Datarange.Text), olByValue, 1
       Next i
       .Send
   End With

If you were to put the email address for the cc in the second column of the
catalog or directory merge document, then you would need to change

       For i = 2 To Maillist.Tables(1).Columns.Count
           Set Datarange = Maillist.Tables(1).Cell(Counter, i).Range
           Datarange.End = Datarange.End - 1
           .Attachments.Add Trim(Datarange.Text), olByValue, 1
       Next i

to

       For i = 3 To Maillist.Tables(1).Columns.Count
           Set Datarange = Maillist.Tables(1).Cell(Counter, i).Range
           Datarange.End = Datarange.End - 1
           .Attachments.Add Trim(Datarange.Text), olByValue, 1
       Next i

so that the macro starts looking for the attachments in the third column
rather than the second.

Hi, I found the solution myself. It worked out well when i did not use the
wizard, but clicked the buttons on the merge tool bar. When I finally clicked
the fulfill-button (I'm not sure what it is called in english, I'm using the
norwegian version of Office), and then ran the macro, it worked out fine.
The "MailMerge with attachements"-function should really be a default option
in MS Office. But that is probably out of your hands....
Thanks for your help, your macro really helped us.
