Setting email priority in access97 vba code

I have this piece of code I use in Access97 which sends an email to Groupwise5.5 and it works just fine. What I would like to do is add a priority to the mail being sent but I do not know what the line of code is. I have tried
oMessage.Priority.High and oMessage.Priority = High
nether works. Also, what is the line of code for putting a mail address in the CC box?

Set oApp = CreateObject("NovellGroupWareSession")
Set oAcct = oApp.login("", "")
Set oMessages = oAcct.Mailbox.Messages
'create new message
Set oMessage = oMessages.Add()
'get mail address
oMessage.Recipients.Add ToYou
oMessage.Recipients.Add ToCC
'get subject for message
oMessage.Subject = Subj
'get message text
oMessage.BodyText = Mess
'get attachement if any
oMessage.attachments.Add AttchFile
'send it out
oMessage.Send

thanks for any help
