My blackberry is configured to run from Microsoft Exchange Server, and I used to be able to run all my email fine from it. Now, I can still receive emails, but I cannot send emails from my BlackBerry.
My phone provider suggested resending the service books, so i did, but it did not work.

Any idea how to fix this, or does anyone know how I can delete the exchange email account from my blackberry and start over...??????


thanks in advance for the help!!!!
