Hi Tom,

In the outlook client Microsoft CRM Menu bar, click on Tools>Options.  There are 3 checkboxes at the bottom.  This is why all the Contacts, Tasks and Appointments came over into your Outlook folders.  If you want to prevent this from happening in the future uncheck these boxes.

 

Also, when you choose the Go Offline button, there is a checkbox at the bottom of the dialog box that says 'Do not update Outlook'  You will want to check that box.

Let me know if you have any further questions.

Amy
