This study investigates the relationships between the use of various organizational ICTs, communication visibility, and perceived proximity to distant colleagues. In addition, this study examines the interplay between visibility and proximity, to determine whether visibility improves proximity, or vice versa. These relationships are tested in a global company using two waves of panel survey data. ESM use increases communication visibility and perceived proximity, while controlling for prior levels of visibility, proximity, and the use of other organizational ICTs. The influence of ESM on network translucence and perceived proximity is generally stronger than the impact of other technologies on these outcomes. These results highlight the importance of considering various aspects of the technological landscape conjointly, as well as distinguishing the two dimensions of communication visibility. Finally, the results indicate that perceived proximity has causal priority over communication visibility, indicating that communication visibility exists partly as an attribution of perceived proximity to distant colleagues, and is not solely inferred from the use of organizational ICTs.
