Thank you, Guessed.
You put me on the right track: I changed
Set olApp = OutlookApp ()
into
Set olApp = GetObject(, "Outlook.Application")
as in the macro of Ron de Bruin.
So now in principle it works fine.
I have one question though. Perhaps someone could solve that as well:
In my Outlook AddressbookI have a number of recipients gathered in GROUP.
I would like to have as recipient this GROUP (several addresses, but in the To: field only visible as "+ GROUP").
Could you please help me with this also?
Many thanks!
Regards,
