Original KB number: 2585157
Symptoms
You find the performance slow for the Microsoft Dynamics CRM 2011 client. When you investigate Microsoft Dynamics CRM client and server network traffic, you find that there's traffic even if there's no Microsoft Dynamics CRM user activity that is occurring.
Cause
The Microsoft Dynamics CRM client for Microsoft Outlook runs background polling activities that communicate to the server and react to server-side changes even if there's no client-side activity.
There are caches for various Microsoft Dynamics CRM features such as address book, reminders, and views. The default polling interval for MAPI caches is every 15 minutes.
The regular polling generates Microsoft Dynamics CRM background activity, and this activity may influence performance.
Resolution
There's a set of registry values and subkeys that can be modified to tune the polling intervals.
The following table contains the list of Microsoft Dynamics CRM client for Outlook registry entries and subkeys that influence background CRM activity. Test and find the optimal values for your environment. As a starting point, there's a Suggested Testing column that doubles the default values.
