Hi all, We use the third party as our MX record and route to our exchange server. Just wonder what if our exchange server is not working, Is there a automatic way to route our mail to our another exchange server (DR)? (exchnage 2003) Thank you.

Yes, There would be a seeting for gateway which you can change any time if there is issue in Primary site (Most company have this kind of setup) like postini. Only your DR site should be configured to recive mail for your adress space. Anil

Hi, You can run exchange 2003 in a clustering environment. More information, please refer the following articles: http://technet.microsoft.com/en-us/library/aa997507(EXCHG.65).aspx http://www.msexchange.org/tutorials/Implementing-Two-Node-Cluster-Windows-2003-Enterprise.html
