@Shyamsundar Manian - Thanks!! I very much appreciate you reading the posts!
@Sazonov ILYA [ sie ] - Thanks for the comment. As a Microsoft guy, I'd like to quit pointing our customers elsewhere as well, but I guess Microsoft can't do everything. I guess we'll see if they want to take that to the next level.
Another idea that I've heard expressed is that we should just make our email clients and servers such that load balancing is not needed, or that the load balancing and client failover is "built in" and transparent to the user. Personally, I like that idea even more - remove the need for load balancing and have it all built into our products out of the box...
Once again to both of you and everyone else that has commented - thanks for reading and thanks for the great comments!!
