Change the interval for the Office Store access checks

  1. Open the following two Web.config files in the Client Access Server:
    • %ExchangeInstallPath%ClientAccess\exchweb\ews\web.config
    • %ExchangeInstallPath%ClientAccess\Owa\web.config
    • C:\Program Files \Microsoft\Exchange Server \V15\ClientAccess\exchweb\ews\web.config
    • C:\Program Files \Microsoft\Exchange Server \V15\ClientAccess\Owa\web.config
  2. In each Web.config file, add the following line between the "<appSettings>" line and the </appSettings> line.
    <add key = "KillBitRefreshTimeInSeconds" value = "<seconds>" /> 

    For example, the following line sets the interval for Office Store access checks to 86,400 seconds (1 day):
    <add key = "KillBitRefreshTimeInSeconds" value = "86400" />
