@MitchMG and Anon-1: I don't think you will get any argument from us that WE must ensure Exchange releases are trouble-free. Having been close to support for years though - I think the problem Ross is describing is much more than "being gun-shy on latest
Exchange releases". In some cases we are talking being a year or more behind on Windows updates, clients or yes - Exchange. While on a certain level, a very good argument for caution and careful testing can be made for any of those 'levels' of patching, all
we are saying is that we have seen cases where that has been taken too far. The number of support cases I have seen because network card drivers were 2-3 years out of date... (just picking on an example).
Again, you both definitely have a point.
