You may be familiar with the Outlook client diagnostic tool located at Start >All Programs >Microsoft Dynamics CRM 4.0 >Diagnostics. When you run the diagnostic wizard, it will find and even fix some of the most common problems with CRM 4.0 for Outlook. However, were you also aware of the advanced diagnostic tools available with the CRM 4.0 web client?
When you run the diagnostics tool, instead of clicking "run diagnostics," click the support mode button.
This will give you two tabs to choose from. The Synchronization Troubleshooting allows you to enable/disable specific synchronization processes.
The Advanced Troubleshooting tab includes options similar to the CRM server diagnostics tool, but this time for the client. You can turn on tracing, delete Outlook temporary files, and create a file that includes relevant logs and machine profile information.
If you ever have issues with a PC running the Outlook client, you will save significant time dealing with Microsoft support if you first create a trace file of the issue and generate the troubleshooting file for support and submit with your support case.
