Hi all,
I'm using this procedure in order to send mail:

Set iMsg = CreateObject("CDO.Message")
Set iConf = CreateObject("CDO.Configuration")

With iMsg
Set .Configuration = iConf
.To = "
.CC = ""
.BCC = ""
.From = """Max"" "
.Subject = "Mail Subject"
.TextBody = "Text Example"
.AddAttachment "C:/Temp/" & WBname
.Send
End With

all works fine on my computer, but in office I receive this error message:

RUN TIME ERROR (80040220)
Configuraton Value "SendUsing" is invalid.

Please, can someone tell me what is the cause?

Thanks in advance
JFM
