I've recently upgraded a pc which is used by multiple users to win7 and Office 2010. Individual mail profiles for 6 users were created in Control Panel - Mail.
They log in to the PC through AD with a generic profile, but have their individual email boxes.
What happens when they load Outlook 2010 and choose their personal mail profile is the password prompt pops up, but if they hit the 'cancel' button, the cached mailbox for the selected mail profile loads which allows anyone to see a particular users email. Outlook does not connect to exchange though since no login was provided.
Previously they were using Outlook XP (2002), where if you hit the 'cancel' button, Outlook would just close down.
To allow for this behaviour, the security settings under the account profile had to be set to 'None', but this option is no longer available in 2010.
I need the same Outlook behaviour which we had in version XP replicated in 2010.
I've tried running in cached mode and not... same problem. I also enabled the 'Always prompt for logon credentials' checkbox which did not help.
