New Domain - Outlook Asks for Credentials RRS feed

  • Question

  • My company is migrating/ has migrated all of our users PCs to a brand new domain on all new infrastructure over a weekend. All new fiber connections from the server room to the distribution points in the building, on all new switches, all new servers, on a brand new domain. The only thing that is remaining the same are the user PCs and the ethernet copper going through the wall to their office room wall port. We are simply swapping the patch cables from the old switches in the rack to the new switches.

    NOTE: all systems are running either Windows 10 Enterprise, or Windows 7 Enterprise (64-bit) and either Office 2010 or 2013.

    Every PC has no problem connecting to the new network, getting a new IP from the DHCP server, and can be disjoined from the old domain and added to the new domain, no problem. We reboot the system, and login with a domain admin account after joining the system to the new domain and add the user account to the local administrator group so that they can install software and whatever else they want to do.

    Login as the user with their [new] domain account - open Outlook 2013, connecting to the Exchange 2013 environment for the first time on the new network. The profile creation wizard guides the user through, finding a matching mailbox created prior via the network admins but then they are prompted for a username and password (exactly the same credential as the network login, both account login name and password). If the user checks to box to "remember credentials", Outlook will then open without issue and boom, they have mail.

    If the user logs out and back in or restarts the computer, and opens Outlook, they are again prompted for credentials and the option to have their credentials remembered if they check the box. How can we make this prompt stop?

    NOTE: We did not run into this issue in testing because we imaged new machines for testing and joined them to the new domain, having never been on the original domain. Exchange, Outlook runs flawlessly, never prompting for credentials, even when first creating their new Outlook profile. We have re-imaged an existing system and joined it to the new domain and it now works flawlessly, but it would take us a very long time to re-image/upgrade every system in the building.

  • Hi,

    Please try testing on one machine by removing all previously saved credentials in Windows Credential Manager and see if the issue still persists:

    1. Click Start, click Control Panel, and then click Credential Manager.
    Note If View by is set to Category, click User Accounts first, and then click Credential Manager.
    2. Locate the set of credentials that has Outlook in the name.
    3. Click the name to expand the set of credentials, and then click Remove from Vault.
    4. Repeat step 3 for any additional sets of credentials that have the word Outlook in the name.

    Besides, it is also recommended to try creating a new profile for an affected user and see the result.  

    Regards,

  • There are no saved credentials in this location. These are brand new profiles that users are logging into, as they are logging into new accounts created on the new domain. But thank you for replying.

  • Hi,

    What if clicking cancel when the prompt occurs?
    Have you checked if there is any difference in connections status between the problematic machines and the working ones?
