Iron Mountain the records management services giant today announced that it was buying e-mail archiving vendor Mimosa.  Mimosa is certainly one of the more prominent solutions in this market, with a number of fairly unique approaches that we detail in our e-mail management and archiving research. However, the fact that Iron Mountain had previously OEM'd a product from Mimecast made this something of a surprise acquisition.

The Mimecast-based hosted solution will apparently continue to operate alongside the onsite Mimosa based system, but it will be interesting to see how this eventually works out.

For buyers of Mimosa's system this is likely pretty good news, as Iron Mountain brings more finances and expertise to support and develop Mimosa than its founders could.  For users of the Iron Mountain Mimecast-based service, you will likely want to get firm answers from your account rep about whether and how it will remain supported in the longer term.
