Emails from Exchange t o BlackBarry instant message

Let me help clarify. Are you asking if there is a way to sync your Blackberry with Exchange without using Blackberry Enterprise Server while getting the same push email functionality?

As technicasoluti& explains, i am already using it with monthly subcribtion to Telecom company.

I need a microsoft solution, that from exchange 2k3, will provide  the same push email functionality without using Blackberry Enterprise Server and monthly subcribtion to Telecom company.

And to be even more clear here is a guide:

Configuring your Blackberry to use
Outlook Web Access
You will be using
" BlackBerry Internet Service
" Microsoft Exchange
" Microsoft Outlook Web Access

Important: Some mobile phone service providers do not support integration with
all email account types - but most do. Contact your mobile phone service provider to verify that
Microsoft Outlook Web Access is supported.

Procedure

For BlackBerry Internet Service accounts, complete the following steps:
1. Navigate to the BlackBerry Internet Service web site (you may need to speak
to your mobile phone service provider to find out where your BlackBerry
Internet Service web site is and for them to set you up an account  if you do,
you may as well ask them to set your Outlook Web Access Account up for you
for use with your blackberry  otherwise carry on below).
You may be able to do this from the wizard on the handheld too.

2. Log in to your BlackBerry Internet Service account.

3. Click Setup Account.

4. Complete the Email address, Password, and Confirm password fields,
and click Next.

5. The following message is displayed: We were unable to configure <email
address>. Choose one of the following options and select Next.

6. Select I will provide the settings to add this email account and click
Next.

7. In the Outlook / Exchange section, select I can access my email
account using a Web Browser (Outlook Web Access), and click Next.

8. Type the Microsoft Outlook Web Access URL
https://www.example.com/exchange
and fill out the required fields.
Note: The Email account field refers to your mailbox name

9. Click Next. The OWA account should appear in your list of integrated email
accounts.

The Blackberry devices are designed to be used with a BES or BIS.
If you don't like that, then send them back and get ActiveSync compatible devices. Windows Mobile, or one of the licensee holders. Purchasing the devices means you are buying in to the whole way that Blackberry works.

You don't buy a BMW and then ask BMW to fit a Mercedes engine.

What are the essentional things required to establish BB services.?

In the my comment 25767709, i asked for any solution from microsoft.

What I found are as:

Solutions for BlackBerry Devices:
BlackBerry Internet Service
Partner client application solutions
Hosted BlackBerry service from Microsoft

For your review:

And I gave you the Microsoft solution in 25767731.
As long as you have OWA working the blackberries will use the Microsoft solution.

In your solution a require BIS or BES is required. but if chose Partner client application solutions, i donot need  it.

I have clearly mentioned  as "without using Blackberry Enterprise Server and monthly subcribtion to Telecom company"
