Outlook 2007 wants to create new profile(s) ?

[realized]

We have some 30 brand new dell computers with office 2007 OEM. All the outlook clients are using pop3 hosted service (google apps). Sometimes a user will open outlook and it will ask them to create a new profile.

if i look in c:\documents and settings\username\local settings\application data\microsoft\outlook after i create the profile, the original .PST is still there..

so i need to copy the Outlook.pst to Outlook1.PST and reboot outlook.

why would outlook create another profile if the pst and other files needed are still there in their correct profile directory?

what would cause outlook to think it needs to create another profile?

this has happened 4 times in some 3 months, 3 of the times being earlier today.

our office had a power outage, but to my understanding the computers were not restarted.. and once again - the profile folders were in tact, and the outlook data files were in tact.

Thanks guys!
