The introduction of the Internet in the 1990s, including near-instant messaging (email), instant messaging (IM) solutions and The World Wide Web, has changed the nature of both commercial and social interactions. The invention of Web 2.0 technology (McAfee 2006), which enables a two-way communication method, interoperability, and user-generated content (UGC), has enabled businesses to create virtual communities and a collaborative environment to host web-based communities as support. foundation of value creation. Social networking sites (SNS), such as Facebook, Google+ and Twitter, are just a few examples; these sites provide space for both greater collaboration and a large amount of user-generated content (Kaplan & Haenlein 2010), which allows the user to become the true owner of the data and information. “Social media in the workplace offers employees new ways to interact with colleagues and provides a platform for sharing information” (Leftheriotis & Giannakos 2014, p. ). Email has become a major tool for all business communication; and according to research, a significant portion of employees' time is spent organizing and managing emails. Due to the increasing use of email in the workplace, a substantial amount of company knowledge is stored in individual email accounts and inboxes that are not easily shareable and accessible to others employees. This is an expected outcome, as employees are paid to produce rather than sift through information (McAfee 2006). They therefore use channels and media that allow them to generate new information, such as email. A Davenport study of corporate email users shows that 100% of knowledge workers use email as a communication channel, compared to paper......vis, Bagozzi et al. 1989, p. ), based on the assumption that successful implementation of ESN systems depends on two factors: initial acceptance and continued use. We use the information systems (IS) success model, as proposed by DeLone (1988) and DeLone and McLean (2003), as an overall and basic theoretical model to measure IS system success, that is- i.e. ENS; and we specifically measure the factors impacting the acceptance of such technology and its continued use. We use current technology acceptance models, e.g. (TAM) (Davis 1989), and factors that impact continued use of technology, e.g. Technology Continuity Theory (TCT) (Liao, Palvia et al. 2009), as well as other relevant theories to evaluate and identify a concept that can be used by companies to accelerate the initial adoption, acceptance and continued use of such technology
