From the initial designs in 1987, OpenMail was primarily designed and developed at HP's now-demolished
Pinewood offices, near
Wokingham,
England (also the home of OpenMail's predecessor product family,
HP DeskManager and the original developers of
HP NewWave). HP said that as many as 15 million email accounts ran on OpenMail. The company stopped selling OpenMail to new customers in November 2001.{{Cite web == External links ==
