Access Your Mail & Migrate It Too

ExchangeDefender SplitMX was designed to enable seamless migrations to ExchangeDefender Exchange 2013 without losing any email. Typically businesses schedule migrations around long weekends to make sure no email is lost during the MX record change and migration from the old email environment to the new mail hosting provider.


  • SplitMX functions as an email proxy, duplicating messages and sending one copy to the existing infrastructure and another to the new hosted Exchange 2013 mailbox.
  • It's cloud-based so it doesn't require any software installation. Because it delivers mail seamlessly to multiple destinations migration is less stressful and time sensitive.
  • Built into ExchangeDefender, quick to deploy and manage!

With ExchangeDefender SplitMX the inbound mail is copied to both the existing infrastructure and the new hosted mailboxes, allowing for a seamless transition without email loss.
