I use ms word mail merge to send email from outlook both are office 2007. It was working fine long time but problem started here

1. When I added new pst file so that i can add another personal folder so that i can use two email address and keep each email address correpounding email in seperate personal folder
2. As soon as I created another personal folder, I started MS word Mail merge wizard. It was working fine till last step, even it is showing that it is creating email.

3. But when I looked to outlook it is not showing even single email in outbox folder. nor in sent item.

4. I just deleted that additional folder which i created, and tried again to send email via mail merge, so that i can through default personal folder but still same result.
