Anonymous Authentication not available in Outlook 2007

I deployed Office 365 in an office of about 10 PCs. All went smooth except 3. It kept on popping up asking for username and password. I investigated and the only thing I could come up with was that these 3 PCs were upgraded from Office 2003 to Office 2007 where as the others were not.

 

So I tried to setup Office 365 manually but came across one option that is not available. On my previous setups of O365 I've noticed that Autodiscover sets the network security to Negotiate Authentication where as in the more recent ones it sets it to Basic Authentication. Well it turns out on these 3 PCs Basic is not available. I've attached a snapshot. Could this be why Autodiscover setup is failing in Outlook 2007? all updates are installed as well. I tried removing, full clean up of Office and reinstall but still same issue. This cannot be a group policy because one there's no group policy for Office, and two if it was, all machines would be affected. Please see image below:

  • To get Anonymous Authentication for Outlook 2007 to use Office 365 hosted exchange you must install KB2768023. To get Anonymous Authentication for Outlook 2010 to use Office 365 hosted exchange you must install KB2687608. I did all the testing and it works once these hotfixes or updates are installed. My tests were done after installing SP3 for Office 2007 and after installing SP2 for Office 2010.

  • Hi vttech,
     
    We recommend you check if these users’ passwords are about to expire. Based on my knowledge, when user’s password is going to expire, Outlook will continue popping out a dialog box for you to enter username and password.
     
    Additionally, would you please configure the account using Autodiscover to see if it works? To do this, you need to add a CNAME record for your account. Here’s an article for your reference:

  • As I mentioned, it's not an Autodiscover issue as other machines are working fine. It's only the machines which have previously had Office 2003 installed, it was removed and Office 2007 was installed. Those machines are facing the issue of not being able to add O365 account. And as I mentioned, I believe it's related to a network security option as Anonymous Authentication doesn't seem to be available on those machines.

  • Hi vttech,
     
    To help troubleshoot the issue, we suggest disabling the Automatically detect settings feature in Internet Explorer to see if it works.
      

    Some users once reported that after disabling it and closing IE, the Outlook 2007 auto discovery worked well.
    I also offer you a similar thread for your reference:

  • The problem still exists; Auto detect settings was off. I tried running Office remover to completely wipe and reinstall it but still no luck. I tried installing a trial of Office 2010 but same issue. This only happens on 3 machines which had Office 2003 installed so it leads me to believe somehow it's related to that.

    For now I gave up; just set it up as iMAP which also gives a certificate error every time Outlook is opened. I've read it's related to a local domain issue but can't figure that out either.

  • Hi vttech,

    Please install the latest Office 365 Desktop Setup on your computer to check if the issue still persists.
    To install Office 365 Desktop Setup, please refer to the following link: http://onlinehelp.microsoft.com/en-us/office365-enterprises/ff637594.aspx

    In addition, I also recommend you configure the account in another computer to check whether the issue is related to the accounts.

  • The O365 package is Exchange 1; it doesn't include the desktop version.

  • Dear all

    I have the issue vttech descibes too. To be able to  connect Outlook to Exchange online 'Anonymous Verifcation' is required. On clients where 'Anonymous Verification' is missing, Outlook keeps requesting for username and password, but doesn't connect to the Exchange online server.

     

    I've searched Registry and Internet multiple times but for an unknown reason on some Windows clients the option 'anonymous verfication'  is missing. And I don't want to reinstall the OS.

     

    Please help, because I have multiple clients which have this issue and I can't migrate the users to Exchange online.

     

    Thanks in advance

  • Yes any help would be much appreciated as I'm forced to setup iMAP on the clients with this problem. Of course OS reinstallation will most likely resolve the matter but not a solution in my case.

  • Hi vttech

    I've found a hint which might be helpfull. I'm testing right now

     

    "If you are setting up Outlook 2007 and there is no anonymous authentication option then please run windows update and install all updates for the Office suite. "

  • Dear all.

    The hint on 0365guides was right in the bulls eye.  For Outlook 2010 you need to install KB2687503. after that Anonymous Authentication is present !

  • Hi vttech,

    I see that you've installed all Windows & Microsoft updates. If so, I'd like to know how are things going after you restart the computer. In addition, please make sure that you've installed the latest updates of Office 2007 and the latest updates for Office 365 Desktop.

    Manually install Office 365 desktop updates

    @SmallClouds, thanks for your information.

    You can install KB2687503 also on Windows XP computers with Office 2007. It will also enable anonymous authentication (again).  I've tried.

    KB2687505 isn't installed with Microsoft updates automatically. It's one of the optional updates which has to be selected manually. That is the main reason why some Windows clients had the issue despite of being up to date with patching

  • I tried installing KB2687505 on 2 different machines; both running XP, one with Office 2007 and the other with 2010 but it wouldn't install on either. On the 2007 machine I got an error saying the right product wasn't found. On the 2010 machine it started installing but then gave an error that a compatible version is not installed. and so the problem is still there.

  • Hi vttech,
     
    We recommend you enter the computer’s registry to delete some registry entries to see if it works:
    1. Click Start, click Run, type regedit, and then click OK.
    2. Since you're running Microsoft Office Outlook 2007, locate the following registry sub-key:
    HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Outlook\AutoDiscover
    3. Delete the following registry entries, if they exist:

    o    PreferLocalXML

    o    ExcludeHttpRedirect

    o    ExcludeHttpsAutodiscoverDomain

    o    ExcludeHttpsRootDomain

    o    ExcludeScpLookup

    o    ExcludeSrvLookup

    o    ExcludeSrvRecord

    o    <NameOfYourDomain>.com and <NameOfYourDomain>.microsoftonline.com

     
    Additionally, based on your description, it seems you are using a pre-upgrade Office 365 tenant. As far as I know, Office 365 pre-upgrade accounts do not use anonymous authentication. It uses Negotiate Authentication. Only the account after service upgrade will choose this authentication approach.
     
    If the issue persists, for further troubleshooting, we suggest running a test on your Outlook. Here are the detailed steps:
    1. Open the Outlook client, and then hold the CTRL button and click the Outlook icon in the system tray and select Test Email Auto Configuration
     
    2. Remove the Use Guessmart and Secure Guessmart Authentication, click Test.
     
    Please catch a screenshot of the content shown in the Log tab, and then post it here. With it, we could look deeper into this issue.

  • Msoft's intent is to use the "Desktop Setup" function that is part of the Office 365 initial setup and configuration. At the home page of the Office 365 web portal, click on the gear at the top right and choose "Office 365 Settings", then choose "Software", then choose "Desktop Setup". This downloads a small applet that checks for updates, installs them if needed, and makes any required configuration changes to Outlook, etc. Frankly, this should be done for all users in the Small Business plans when initially setting them up.

     

    The times that I have forgotten to do this first and ran into the "Anonymous Authentication" problem, "Desktop Setup" has fixed it every time.
