Since adding a new user to Active Directory and new PC to the domain, our client has had credentials boxes appearing all day long when they use outlook. Now adding their credentials does make the box disappear, but it then reappears a short time later. One user has also not received emails on their phone since. I added the PC to the domain the manual way, by right clicking computer and then properties and then added it there. Once I had done this, I did also add Domain users to the local admin group so they have access. Is there something that occurs when adding a PC to a domain that causes the credentials box to appear?
I don't know if it is related, but the new user is unable to access a network drive that was mapped the day the PC was added, but she has full access rights set in the security.
The server we use is SBS 2008 if this also helps
