Newly installed Office 2007 Standard version, replacing previously installed
Office 2003, using Windows XP Professional on a defragmented and MS cleaned
40 GB hard drive with 36% free after installation. SDRAM is 1.25 GB.

After easy typical installation of the Office suite, other programs started
correctly (Excel and Word) and are operative.

Outlook 2007 fails to open correctly, despite several "repairs" and
reinstallations and verification by the included program. It shows the
opening title screen, with the additional "Configuring Outlook" box covering
the top left-hand corner of the Outlook pane. Then it hangs, becomes
non-responsive and will not return to Windows without being closed using the
red X in the top right-hand of the top ribbon.

Additional information: I have the old PST files stored in their original
positions, as well as backup PST files on a separate drive. I noted that when
Outlook 2007 briefly opened, the Calendar information for today was showing,
Then, of course, it ceased to function. Just as it did under Office 2003 (see
previous question in June under Office 2003). Are the problems I had then and
those I have now linked in any way?

Any help would be most welcome. Thanks to all those who reply.
