It’s very interesting to see that Cisco has pulled the plug on email having only launched it in Nov 2009.

Quote from the article:

“In the thirteen months since, we’ve been market testing Cisco Mail via a controlled release. The product has been well received, but we’ve since learned that customers have come to view their email as a mature and commoditized tool versus a long-term differentiated element of their collaboration strategy. We’ve also heard that customers are eager to embrace emerging collaboration tools such as social software and video.

That was the key factor in the decision, which we shared with customers today, to discontinue investment in Cisco Mail. As you would expect, we will assist our current trial customers with their transition to other email alternatives and support them for the length of their contract. Cisco will also continue to integrate to other email systems to protect our customers’ legacy communications investments.”
