Who are the main vendors of messaging management tools for Exchange?
Not too long ago, the leaders were BMC (Patrol) and NetIQ. However, Microsoft beefed up its offerings and reduced the demand for NetIQ, which was recently acquired by Attachmate.
The leaders today are Microsoft (MOM) and Quest (Spotlight on Exchange and MessageStats). Quest has taken steps to integrate its solutions into MOM, which is a smart approach to being both a competitor to and partner with Microsoft.
