Migrating to 123Together Hosted Exchange Service is stress-free!  You can migrate at your own pace.  We offer a Split-Domain solution.  For our Dedicated Server clients, it is included in the contracted fee.  For our Shared Server clients, there is a one-time $20 fee.

Migrating to any service, can prove tricky; mail loss, bounce back messages when emailing users at your domain sitting on the old mail server, mistakes due to rushing, etc…
When you migrate to another server environment, typically, you are not able to email anyone @YourDomain.com that is not on the new Exchange server. The cause is that the new system thinks that it is the authoritative email server for your domain, YourDomain.com. So, when it gets an email addressed to a user@YourDomain.com that does not exist yet, on the new system, it rejects it - it doesn’t know about your other mail server.
We can reconfigure your domain so that our Exchange server redirects all unresolved email addresses @YourDomain.com to your current mail server, instead of rejecting it.  This is a seamless solution, and takes the pressure off of your IT Staff during migration.
