There is a very famous alternate solution for you (that'll be posted by other EE too). It's called DAG.

You'll need the following for it.

x2 Windows Ent. Edition Servers
8-16 GB Ram each (depending on the number AND size of mailboxes)
500 GB - 1 TB storage on each server
1 additional server that'll host CAS and HUB Server role.

**You can use DAG with Ex2010 Std edition, however you'd be restricted to max 5 Databases and not more on your DAG solution.

Once you've got the above setup, you are rest assured that you would have least down time (in terms of mailbox access / email delivery) in case if any one of the DAG Members are affected.

Dear Exchange_Geek  
Thanks.
The DAG solution :
1- for Datadabe if currption or dwon time in existion Datadabe  it transfer to DAG database.
2- if installed another exchange with DAG   if failed one exchange you can use exchange with DAG.
3. if main exchange server failed down, how the outlook will use exchange with DAG, is the Outlook auto change configuration  for all users to use  DAG exchange ..
4. if main exchange server failed down how to can configure exchange sever 2010 to use DAG .also what about IP address confiuration.

5. but, example if Link or lease line failed down for any reasone for some time what is the soluion.
1- for Datadabe if currption or dwon time in existion Datadabe  it transfer to DAG database.
It would be automatic, there is no manual interference required - if database gets affected on Server1, Server2 automatically picks up the database and mounts it.


2- if installed another exchange with DAG   if failed one exchange you can use exchange with DAG.
Refer to answer stated above.


3. if main exchange server failed down, how the outlook will use exchange with DAG, is the Outlook auto change configuration  for all users to use  DAG exchange ..
OL connects to CAS Server not DAG Servers, they would stay connected as long the database is mounted on Server 1 or 2. So, you don't need to worry. As long as Server2 mounts your database - users wouldn't even know that database failed over from Server1 to Server2.

4. if main exchange server failed down how to can configure exchange sever 2010 to use DAG .also what about IP address confiuration.
You can read that from DAG installation guides - google you'll find them in tonnes.

Thanks  Exchange_Geek .
 
Thank you for you explaintion .

1- also I want know if the line or lease line down, which is connected to echnage server and have fix IP (external Ip address ) by ISP. what could be the solution.
2- also if you have another line from (ISP)  with fixed IP address how we can use  if main line or lease line down to send and receive email .
That's more on the networking side of the question, I think if you have fixed IP Address provided - you could use a VPN Tunnel created that'll help you send traffic between servers using internal IP Address, cause you wouldn't ask Exchange to talk to internet provided IP Address right?
