I get a message that says Cannot open your default e-mail folders. Outlook cannot start because a data file to send and receive mail cannot be found. To add a data file such as a personal folder file, double click the MAIL icon in Windows control panel. When I try to add a folder I get message that says This information service is not installed on your computer. I removed Office 2010 from my computer and reinstalled Office 2007 but still cannot get Outlook to open.
