Hi leondigiduck,
I immediately tried your suggestion but for me it doesn't seem to change anything.
Did you choose a specific order for the items in the "custom" list? I tried several, but when not connected to Outlook and trying an addres-never-tried-before, it still says that it must be connected to Exchange in order to be able to send the message.

Maybe you did it slightly different than I did anyway.
Could you provide more details?

Johan
