    Recommendation for FE:BE= 1:8

    Its always goot to have 2 FE under NLB for fault tolerance. Regarding your number of BE servers, you need to consider users mailbox sizes as well.

    Why dont you go for exchange 2007?

      Best thing to do? Hire a consultant.

      Planning a site for 11,000 users is not really something that could be done through a forum. TO design something like that, I would be on site two or three days just doing the design. With all due respect, no one is going to give you 2000 or more of consultancy for free.

      That is a major site, and it needs to be treated with care. If you want high availability then you are looking at clustering. If you insist on sticking with Exchange 2003 then you are looking at multiple servers. 4 isn't really enough.
