OK, this is a must read report if your interested in managing email chaos ! I know, because I have read it already..... :-)
This is another exemplary piece of CMS Watch analysis, not just disecting some of the technology / products available in this space, but concentrating on what you need to know about archiving and managing email messaging, and most importantly, focusing on the possible fit between one of the available solutions and your own specific business requirements.
In my opinion this would be a good read for the 'C' level individual who does not need read the indepth analysis of each product, but does need some hand holding at the high level - the 'EAM' for dummies section, whilst at the same time, if your an experienced Exchange or Notes admin, there is still a lot here for you to get your teeth into.
Of course from a wider ECM / Information Management perspective, you might need to come at EAM from a records management or compliance angle too.
Lets face, when it comes down to it, most organisations are a long way from ECMS based content centric collaboration, full use of Instant Messaging or 'conversational media' such as blogs, email is the lowest common denominator and like all forms of digital content creation (across all media) the volumes just continue to grow and grow !
