About the Messaging Client AddIn Cache Refresh Interval Parameter
You can optionally specify a value for the MsgClientAddInCacheRefreshInterval parameter. The MsgClientAddInCacheRefreshInterval parameter defines how often, in minutes, the Siebel Outlook Add-In refreshes the local cache for all users.
The local cache is used to store the linked Siebel data that is displayed in Microsoft Outlook. Storing a copy of the user’s Siebel data in a local cache improves performance and allows the user to work offline. In determining the refresh interval of the local cache, you must consider the necessity to have current data available against the performance impact of updating this information repeatedly. For information about how individual users can modify the refresh interval values in Outlook, see Setting the Cache Refresh Interval.
