MSN Messenger versions don't have an integrated Offline Messaging system. But the
Messenger Plus! 3.63 extension adds this functionality to MSN Messenger versions. (I'm not sure Windows Messenger is supported for this function of Plus! but MSN Messenger 7.0 and 7.5 must be supported.) Note that you must be Online at the moment of your contact comes Online since Messenger Plus! stores the offline message on harddrive, not on a server. I wanted to write these since you wrote

Hi,
How do I send a message to an Offline contact so that she can get the message when she goes Online while my pc is Online?
However in Windows Live Messenger (the name of the latest version of classic MSN Messenger) Offline Messaging is integrated to the software and Offline Messages are stored on the Messenger servers and sent to contacts when they come Online regardless of you being Online at that moment.
