Lookeen

Lookeen was developed in 2007^[1] as an email search tool replacement for Lookout,^[2][3] which left the market when it was purchased by Microsoft.^[4] Lookeen enables users to search for files on their local drives, Microsoft Outlook and Microsoft Exchange Server files, and any connected network drives from standard or virtual desktops.^[5]

Lookeen won the About.com Reader's Choice award for Best Outlook Add-In in 2010^[6] and 2011,^[7] and has been reviewed by PCMagazine,^[8] The Atlantic,^[9] Inc Magazine,^[10] PCWorld,^[11] and Ghacks,^[12] among others^[13][14][15] Lookeen was also one of 29 productivity apps recommended in an article on TechCrunch in September 2015.^[16] Lookeen was also mentioned as a 3rd party search utility by The New York Times in December 2016.^[17]

Lookeen is built upon the open source software, Lucene. The index framework builds an inverted index to allow fast full text searches within indexed content. Lookeen uses Microsoft add-in technology to integrate a search bar and ribbon into the Outlook client.

Axonic launched enterprise search capabilities in 2012 with Lookeen Server, a Microsoft server-based index which can deliver search results to multiple desktop clients. A free version, Lookeen Free, was released in 2015.^[18]
