I have a new Dell Inspiron running Windows 7 x64. I have installed Microsoft Office 2010. My old laptop is a Dell Inspiron 9300 running Windows XP 32bit. I have Microsoft Office 2007 installed on it. I had received a number of emails in Outlook 2010 on the new computer. I went to the older computer and casually checked my email in Outlook 2007. It received all the emails I had already received in Outlook 2010. Later, when I tried to check my email on the new Outlook 2010 all the emails I had there were completely gone. I have repeated this action several times and the same thing happens each time. Why is this happening? And what can I do to stop it? My ISP is charter.net. Any help will be greatly appreciated.
