Adding an Attachment to an Appointment

If you add an attachment to an Outlook calendar appointment, the attachment is not synchronized with the Siebel application because SSSE does not currently support synchronization of calendar attachments.

The attachment remains attached to your Outlook appointment even if you change appointment details in the Siebel application and resynchronize with Outlook.
