Obtains the number of rows in the Table.
Assembly: Microsoft.Office.Interop.Outlook (in Microsoft.Office.Interop.Outlook.dll)
GetRowCount on a large table will result in a performance impact. Due to MAPI restrictions (for example, memory constraints for large tables, simultaneous operations on the Table), GetRowCount may not be able to determine the number of rows in the Table, or it may only only return an approximate row count. In these cases, GetRowCount will return an error. You should use appropriate error detection for GetRowCount to determine if the call returns an error.
