Hi John,
Outlook synchronization will only work with Microsoft Outlook not Microsoft Outlook express.
When you have configured your outlook synchronization, select appointments and tasks between the Max Address Book and Microsoft Outlook can be synchronized. Only those appointments and tasks scheduled within the specified date ranges will synchronize.
If a task is scheduled prior to the specified date range, but the 'carry forward unfinished tasks' option is selected, the task will be synchronized.
Hope this helps.
