I am planning a migration from a Lotus Notes to Exchange 2013 environment that is site resilient. I understand that there will be a migration period and that the mail routing design will look different during that time of the migration. I have been researching the architecture of Exchange 2013 and I feel I have a pretty good understanding of most features in the CAS and DAG roles but it is really unclear how inbound/outbound external mail routing is configured. In previous versions many people used the Edge Transport server and I can still use the Exchange 2010 Edge Transport server in 2013 as one option. I am also finding information that I can setup send and recieve connectors on the Exchange 2013 CAS servers to do this task too. Below are my questions about this topic.
- Am I right that Exchange 2013 CAS or Exchange 2010 Edge Transport are options for this service?
- Are there other option for Inbound/Outbound External mail routing with Exchange 2013? Third party or otherwise?
- Of all my options what are the pros/cons to using each one.
- I have heard rumors of an Exchange 2013 Edge Transport service that is planned for future release? Are there any details on what this will feature, when it will be released, or how it will work?
