Outlook 2007 prompted to restart when try to send out email

Hi,

*Unable to send emails to external contacts. Only able to send emails to internal contacts.*
*Using Microsoft Exchange.*

I tried to send out an email to internal and external contacts in the first place but then Outlook prompted to restart. I restarted the Outlook thought maybe its the add-ins problem so I enable the add-ins but then when I try to send out the email again, it did not ask me to restart but close the program instead.

Did a test send to internal contacts only and it sent out (works) but with external contacts it gives the prompt again.

Problem solved: I deleted the Outlook profile and recreated it. Test send to internal and external contacts, WORKS!

*But instead of recreate the profile, are there any other ways to solve the issue?*

regards,
Booog
