I just heard about Windows Essential Business Server for the first time yesterday. We currently have Small Business Server, and were thinking of migrating to the standard server products. We're approaching the limit on number of mailboxes.
From reading the Microsoft web site, I can't tell whether Essential Business Server is a good idea, or whether they've packaged the standard components together in some novel way that although is supposed to make things easier, results in something harder to keep running reliably.
Has anyone used EBS? Do you find it delivers on Microsoft's promises?
