You can change the setting for how often the Web Messaging (Web Client ) e-mail message list auto-refresh occurs. In the IClient.config file (usually located in \Program Files\Ipswitch\Collaboration Suite\WebDir\WebClient), under the <appSettings> node, change the value for the following AutoRefresh key:<add key="AutoRefresh" value="300"/>.
This key contains a numerical value that corresponds to how often the auto-refresh occurs. By default this value is set to 300 seconds (5 minutes). Please note that the word "seconds" does not appear in the value. Only numerical values are valid for this key, for example: 300. If for any reason you want to disable the e-mail message list auto-refresh, set the value to 0.
Note: The AutoRefresh setting affects all Web Client users.
