So I still get the "message sent" pop up

[Matchstick]

Hey everyone,

The last time I did a hard reset on my Alltel Titan was because it was slowing down a lot. But I've noticed now that whenever I send a text from the Outlook SMS program it gives me that "Message sent" notification. I found that to be especially annoying, so I went and got the nosentmsg cab file and ran that. And it STILL gives me that notification. It doesn't do that when I'm running VITO SMS chat. But I'm not liking the lack of autocorrection in there so I want to go back to using the Outlook SMS. But I can't stand that notification. Any ideas on how to get rid of that?

Thanks in advance,
The Matchstick
