I have enabled Server-Side synchronization for Incoming mail, outgoing mail and Appointments, Tasks and Contacts on mailboxes in Dynamics CRM 2013. The mailboxes have been approved and enabled and also statuses for all 3 modes are successful.
However, Contacts, Tasks and Appointments created in CRM are synced properly in the Office 365 web application. But not the other way round. What must have gone wrong?
When properly configured, any task/appointment/contact created in CRM will be synced to the user’s Exchange mailbox. Once synced with Exchange, those same items can then be edited directly in the Exchange side (Outlook), and changes will reflect back in CRM. It will not sync a Task, Appointment, or Contact created directly from Exchange, since the majority of them are personal and do not need to be in CRM. http://crmbook.powerobjects.com/system-administration/server-side-sync/advantages/
