GreenTools for Microsoft Apps (G4MS) has been updated so the G4MSMAIL addon will now allow you to specify wildcards for the attachements. This will work when called through MAILTOOL or using the G4MSMAIL ILE functions as well.
It will allow the use of the following wildcard situations
*wildcard
wilcard*
wild*card
You will will need to specify the fully qualified path, but you may use any of these three types of wildcard options for filenames.
