Answer / Solution

The Exchange Server Toolbox is fully compatible with a Shadow Redundancy configuration. Here are the key points you should be aware of:

1. Installation and Licensing:
   
   • You need a separate installation and license for each Exchange Server.
   • Set up one installation as the master and all other installations as clients.
2. Email Processing:
   
   • Each Exchange Server Toolbox installation processes emails locally, regardless of whether it is the master or a client.
   • The rules are applied locally, which means that rules with the condition "Machine name equals text" can be used here.
3. Archiving:
   
   • The master installation is always used for archiving, regardless of which installation processed the email.
   • Outlook installations must connect to the master installation to use the archive search of the Outlook Add-In.
4. Failover:
   
   • If the master installation is not reachable, the Exchange Server Toolbox stores emails in a local queue.
   • These emails are forwarded to the master installation as soon as it becomes reachable again.

This configuration ensures that your emails are always correctly processed and archived, even in a high-availability environment.
