sample sales: "What is a .wab file and how do I open it/use it? I have about 500 contacts in this file that was sent from a colleague, and I'm supposed to send out a sample sale flyer to them but I don't even know how to work the thing. I was somehow able to add the contacts in the wab file to my general contacts but I need to send it to those 500 specific people not all the 1000 people in my contacts!" thats the email I got from my friend's dad, but I'm a mac user so I've done some research on the web but I can't really find anything useful. Anyone?|||It is the outlook in the communications inside the thin lead out of the suffix for the generation of wab file. Jacky|||.WAB is a Microsoft Outlook file. There is no way to send an email to a list of contacts in a .WAB file. You could try exporting your other contacts, DELETE THEM, then import the .WAB file, and send it.
