have recently bought Windows Vista Premium on an HP PC. I am really pleased with the new features of Vista. However I am unable to send a calendar appointment from my laptop (running Office 2003 on WIndows XP) to my windows mail account (on my PC) and save this on the calendar - there is no attachment showing on the email received nor any indication it is a calendar appointment file. I thought it was security settings - windows mail not displaying attachments, however I am able to view other attached files and all security settings I believe are correct.
Does anyone know if this is possible and i what I may be doing wrong?
