You appear to have added the second createfolders macro instead of replacing the original, hence the ambiguous name.

As long as the path you are saving to exists (here fPath = "\\myserver\folder\") , you can simplify the code to the following
Don't forget to put your own domain name in the line - If olItem.Sender Like "*@gmayor.com" Then 'Your domain:
