Exchange 2007 - Failover
Hi, I have an Essential Business Serverenvironmentdeployment. It is running at our offices. We don't have power backupect.toguaranteethe servers and network will be up the whole time so I will need some kind of off-site mail redundancy. We currently have a POP3 service hosted that catches our mail. I am looking to integrate these to to do failover. My idea is to modify the MX records with the Exchange server as primary. This is all fine so far? Well when the Exchange comes back up what is the most efficient way get the mail from the pop3 server. Maybe I'm heading down the wrong path. Please help. A

This really comes down to your budget and what your architecture looks like.Have you looked at the following link? New High Availability Features in Exchange 2007 SP1:http://technet.microsoft.com/en-us/library/bb676571.aspxandhttp://msexchangeteam.com/archive/2007/06/28/445538.aspxIf your accessing things via pop3 you will have to manually change DNS records internally and externally. You will need to deploy a warm site. In the event of a failure there are many manual steps you would need to take to recover the mail data and allow access back into the mailbox. What you could do is have two MX records, say a 10 for your production environemnt and then a 20 for your DR. IN the event the 10 is not available things will go to the 20. Make sure 20 can communicate with the 10 datacenter incase mail does go that route. But be wary, some spammers will target the higher MX records with spam so you may want something in front of the Hub Transport server at the DR location.Hope this helps.BP
