Issues with outlook - external domain RRS feed

  • Question

  • We have an exchange server (2010) which has been servicing 12 trusted domains for several years.

    Yesterday users from one of our domains reported that they were being prompted from outlook to enter their passwords. We verified that all DNS trusts were being properly validated (as we have seen in the past that when this occurs our trust relationship had been broken) we checked WINS to ensure resolution. This is NOT an issue with Microsoft credential manager. 

    Any thoughts?


    Thank you, Chris

  • I often see credential prompts when users switch from one network to another, for example a WiFi to wired, or Internet to VPN.
