Alt Message Classes Tag of the siebel_basic_mapping.xml File

To define an alternative message class to an object in Microsoft Outlook, you can use the alt_messageclasses tag. This tag is useful if a CRM object might be in one of several different states. For example, a contact might be shared or not shared.

This tag must contain a set of alt_messageclass tags that define each state of an object. The alt_messageclass tag can also define a form that you use for an object with this message class. This way, you can use different forms for the same object, but in different states.

Each alt_messageclass tag includes the following attributes:

• Ext. Indicates an extension that is added to an original message class.
• display_name. The same as the message_class tag.
• icon. The same as the message_class tag.
• large_icon. The same as the message_class tag.
