This study examines employees' perceptions of digital internal communication channels in relation to their effectiveness and usability within a specific organization. By employing a mixed-methods approach, combining qualitative data from interviews and quantitative data from surveys, various themes were explored. The study investigates participants' preferences, the primary communication channels utilized, and their perspectives on the effectiveness and usability of these channels. The findings indicate that employees predominantly favor Microsoft Teams and email as their preferred communication channels, citing ease of use, functionality and information sharing as key factors. Recognizing and understanding employees' preferences can enable the organization to identify and optimize effective communication channels for internal processes, fostering an environment that is more efficient and conducive to collaboration.  It is crucial to acknowledge the study's limitations. The findings are context-specific and may not be readily generalizable to other settings. Alternative interpretations of the results are possible, necessitating further research to delve deeper into these aspects. By considering the insights from this study, organizations can make informed decisions to improve and select appropriate digital internal communication channels tailored to their specific requirements.
