Later synchronizations are faster because only changes and additions are being synchronized. The best strategy for speedier synchronization is to reduce the amount of data. Here are a few suggestions that might help speed up synchronization:

• Determine if you need to synchronize contacts, tasks, and appointments. If not, you can turn these off in the Set Personal Options dialog box. In Microsoft Dynamics CRM Online for Outlook, on the Microsoft Dynamics CRM menu bar, click Options. In the Set Personal Options dialog box, on the Synchronization tab, you can select which record types are synchronized and how often.
• Increase how often your local data is updated. This reduces the amount of data to be updated when you go offline. In the Set Personal Options dialog box, on the Offline tab, select a shorter period of time.
• Reduce the type of e-mail recipients that are reconciled and therefore need to be synchronized. In the Set Personal Options dialog box, on the Address Book tab, select fewer options.
