IMailFolderFetch Method (IListInt32, IFetchRequest, CancellationToken)
IList<IMessageSummary> Fetch( IList<int> indexes, IFetchRequest request, CancellationToken cancellationToken = default )
Fetches the message summaries for the specified message indexes.
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.
