The Password Manager gets confused and is unable to handle entering passwords for multiple accounts into applications like Outlook and Office Communicator.
Example: I have Outlook 2010 configured to connect to two different exchange server. When I attempt to log into Account 1, it stores the password and will sucessfully cache the password. When the login prompt pops up for Account 2, the Password Manager gets confused and thinks it needs to update the password for Account 1. I can have it enter the password properly for one account at a time, but at no time will it properly handle both.
