Do I need BES to get Push Emails from Exchange?

I'm thinking of purchasing a Bold and we have an Exchange server at work but I don't want to pay an extra $10 for BES. If I opt for BIS will I still get emails from my Exchnage server plus other email servers like Hotmail or Gmail?

Someone has told me I won't get Exchange emails "instantly" as I may have to wait 5 minutes or so which is usually fine with me.

Thanks for any information you can provide.

You will have no problems with Hotmail or Gmail with BIS, but for Exchange e-mails, you will either have to:
1. Set up e-mail forwarding on exchange server side OR
2. Have the Redirector running 24/7 on your desktop

You can also use Outlook Web Access if your company has it. It's a little slower, like you've been told, it will take 5 minutes or so to get most e-mails. There are instructions for setting it up somewhere here on the forums.
