Microsoft yesterday shut down talk that it would soon stop shipping new versions of its Exchange Server, promising customers that it would continue to develop and release the popular email software for on-premise use.
In a post to the Exchange team's blog, Perry Clarke, who heads development, tried to put those fears to rest. "Microsoft has no plans to stop delivering on-premises releases of Exchange," Clarke wrote.

Clarke also said that customers could expect an Exchange release cadence of two to three years going forward, and that engineers are, in fact, working on the next iteration.
Exchange 2010 shipped in November 2009, and the follow-up, Exchange 2013, launched in October 2012, a four-year gap. Prior to that, however, Microsoft took three years between Exchange 2007 and 2010.
"While we are enthusiastic about the cloud, we also understand that our customers will transition to the cloud at their own pace," Clarke said. "Many customers will remain on-premises or in hybrid deployments for the foreseeable future, and we want to keep delivering our newest and best features to them."
Talk of Microsoft pulling out of the on-premise market -- software installed by companies on their own servers -- was driven by the Redmond, Wash. company's aggressive emphasis on cloud-based services, said Rob Sanfilippo, an analyst at independent research firm Directions on Microsoft.
"Customers were wondering that, with so much moving to the cloud," said Sanfilippo, citing Microsoft's pivot to become a "devices-and-services" seller rather than one known for packaged software. "We didn't expect that they would be [dumping on-premise Exchange], but maybe that they would speed up its releases, like they're doing across the board."
So Sanfilippo said he was "a little surprised" by Clarke's confirmation that Exchange will instead hew to a slower development and shipping tempo.
Microsoft sells its Exchange Online service as an a la carte option for $4 or $8 per user per month, or more commonly, as part of an Office 365 subscription plan. The latter includes rights to on-premise Office 2013, starts at $12.50 per user per month and tops out at $22 per user per month.
In the comments appended to Clarke's blog, some continued to complain about what they saw as an emphasis on the cloud-based Exchange service and a corresponding lack of attention to the on-premise editions.
"All we want is to see you guys support the on-premise releases just as well as you do the Office 365 ones," said Chris Merritt, who works for a U.K.-based hosting company. "This to me means releasing the same features for both, and making the tools and functionality work just as well for your on-premise customers as it does for Office 365."
Sanfilippo said there was reason for customers to be concerned about the disparities between on-premise and cloud-based Exchange.
