Exchange 2010 Edge & NLB

I would like to ask:

1-      Is it better to use NLB or multiple MX records?
2-      If I use NLB, what the configuration recommended doing? Is there any guide which can help?
3-      It’s mentioned in the article, "To enable a full synchronization we need the following cmdlets in Exchange Management Shell", what he mean about the full synchronization?

Thanks

If your using your edge server as Application SMTP relay, then you can use for NLB otherwise you have to use Mulitple Mx records for external mail.

hi Sekar,

what do you mean exactly? for what we can use the Edge more that SMTP relay?


Thanks

For Example in your network if you have any applications which is sending mail from the application server.. you can use the edge server as well for relay and those edge servers can be configured as a NLB cluster
