Missing Emails in Outlook 2000

[Jamies]

Help, colleague A is using Outlook 2000 and colleague B is using Outlook
2003, when colleague A used colleague's B machine and then logged back onto
her machine, loads of emails have vanished, she now only has the last two
weeks worth of emails. We are using Windows Exchange Server 2000 and Outlook
2000 and Outlook 2003. I have tried deleting the profile and re-establishing
it, but to no success.

Any advice on how to retrieve the emails.

Thanks,
