It seems when I first setup a new user in Outlook 2007, a login prompt comes up and asks for credentials. After the account is setup, the login prompt will repeatedly prompt throughout the day and is a little annoying. This happened recently as all other machines are not doing this – just a few machines on the network (The new HP 8200 Elite small form factor machines to be exact) Outlook 2007 works perfect on the other HP models we have – HP 6000, Optiplex 330, Opti 320's. A few of the HP 8200's work and the new HP 8200's give us the prompt. Any help would be much appreciated.
