Usage Note
In Visual Basic and C#, you can call this method as an instance method on any object of type IMailFolder. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).Remarks
Fetches the message summaries for the specified message indexes that have a higher mod-sequence value than the one specified.
It should be noted that if another client has modified any message in the folder, the mail service may choose to return information that was not explicitly requested. It is therefore important to be prepared to handle both additional fields on a IMessageSummary for messages that were requested as well as summaries for messages that were not requested at all.
