For example, if you upgrade to Windows 7, you will find that your old Outlook Express contacts and saved emails in the EML format will initially be inoperable when you start using Microsoft Outlook or Windows Live Mail. Additionally, if you change over from Outlook Express to Outlook, you will not have your messages automatically transferred.
Halimbawa, kung ikaw ay mag-upgrade sa Windows 7, makikita mo na ang iyong lumang Outlook Express contact at save email sa EML format una ay walang bisa kapag nagsimula ka ng gamit Microsoft Outlook o Windows Live Mail. Bukod pa rito, kung mong baguhin mula sa Outlook Express sa Outlook, hindi mo ang iyong mga mensahe ay awtomatikong ililipat.
