Outlook 2010 client ask for credential when Exchange 2010 server restart

Hi,
Each time our Exchange server is restarted (most of time for update installation), all open Outlook clients are prompt for credential.
This is annoying because when the users come back, sometime they don't take care about the credential windows and believe that's they don't receive any mail and start to prompt the support when they notice that's their mail come to their mobile but
not on Outlook...
One solution is to ask everybody to shut their computer down every time an update of the server is planned. But as the users are, by design, very lazy and don't really care about this kind of things. It isn't an acceptable solution.
Does anyone know if there is a way for stopping Outlook to ask about credential when it loose temporarily the connection with Exchange ?
Thanks for reading

  • Lync 2010 client asks for credentials when outside of corporate network.

    Hello, 
    We are running Lync 2010 Enterprise. Everytime our Lync users are outside of our network and they log in to their Lync client, they get a pop-up window asking for credentials. When they log into Lync inside our network the Lync client connects automatically
    without asking for credentials. Is this normal behavior? I assumed that the Lync client would behave exactly no matter where they were connecting from. They are using Lync 2010 client on domain joined laptops, I would assume the Lync client would just use
    the same credentials they used to log in to their computers and not ask for anything. Please let me know if there is a way to stop the pop-up from showing up when people try to connect to Lync from outside our network. 
    Thanks for any help!

    Outside of the network the credential popup is for Exchange web services on the back end to check calendar info, contact lookup, etc.  If Lync is already logged in when they see the popup, this is normal behavior.

  • Outlook 2007 Clients Prompt For Password When Opening

    I am running Exchange 2007 Standard.  New outlook 07 clients prompt for password each time it is opened.  Older clients do not prompt for password.  Is there any way for outlook 07 to not prompt for password?  Users already logged into domain, should their credentials not be recognized automatically like with outlook 03?

    This fixed it for me.

    Same problem here after restarting SBS 2008 for upgrades (annoying login box popping up after starting Outlook and also other times). 
    This solved the problem for me:
    IIS Mgr on SBS 2008 / - / SBS Web Applications /
    - SSL Settings / Client certificates - Stop / Start web server after changing settings: 
    Autodiscover: Ignore 
    EWS: Ignore 
    OAB: Accept *) 
    owa: Accept *) 
    Rpc: Accept *) 
    RpcWithCert: Accept *) 
    *) All these have to be Accept to get rid of login box

    I was having the same issue. SBS2008, Exchange 2007. Only being prompted in Outlook 2007 clients. Tried a lot of different things to fix it, but none worked. This started happening after a round of security updates but I could not find KB2412171 on the list.

  • How to Get Outlook Client Version for MAC from Exchange 2010

    Hi, 
    I want to know how many users in my organization are using Outlook for MAC or Email for MAC. What is the best way to extract this information from Exchange 2010 server. I can read the RPC Client Access logs by running logparser:
    logparser.exe "SELECT distinct extract_suffix(client-name,0,'=') as User,client-software,client-software-version as Versio
    n,client-mode,client-ip,protocol from 'D:\RPC\EXTC03\RCA_2014*.log' WHERE (operation='Connect') GROUP BY User,client-software,Version,client-mode,client-ip,protocol ORDER BY User" -nSkipLines:4 -i:CSV -rtp:-1 > D:\RPC\EXTC03\EXT
    C03.TXT
    How to extract Outlook for MAC clients from this command? 
    Hasan

    Hi Hasan,
    As far as I know, Outlook for Mac (Office 2011) uses Microsoft's EWS (Exchange Web Service). So you probably need to collect and focus on EWS logs, not RCA.
    Anyway, Karl is right that you'd better post your question in our Exchange forum, where you can get more experienced responses:
    https://social.technet.microsoft.com/Forums/exchange/en-US/home?category=exchangeserver
    The reason why we recommend posting appropriately is you will get the most qualified pool of respondents, and other partners who read the forums regularly can either share their knowledge or learn from your interaction with us. Thank you for your understanding.

    OWA works Fine no issues

    Hey Alan
    If you have enabled web-based publishing of your Offline Address Book (OAB) and your Outlook users get continuously prompted to enter their passwords, you need to check a couple of things:
    Make sure Autodiscover is working perfectly before you made the OAB change.
    Hold down the CTRL button and right click on the Outlook icon on the task bar, then select
    Test Email Autoconfiguration. Unselect GuessSmart and Secure GuessSmart and keep
    Use Autodiscover selected. On the Log tab, make sure Autodiscover is successful and that it was able to bind to an SCP.
    Make sure that the autodiscover.domain.com entry is added to your certificate’s
    Subject Alernative Names list.
    If you are facing problems with Autodiscover, you should correct that first before attempting the steps mentioned below.
    Make sure that you have defined the External and Internal URLs for the OAB virtual directory in your client access server.
    Once you have made sure that Autodiscover is working OK, and that the credentials are being prompted for the OAB URL (and not the mailbox server), you need to check the IIS Authentication setting on the client access server.
    On the Client Access Server running Windows Server 2008, open IIS Manager console.
    Click on Default Web Site
    Open Authentication
    Note that only Anonymous Authentication is enabled. All other authentication methods should be disabled.
    Temporarily enable Windows Authentication
    Right click on Windows Authentication and choose Advanced Settings
    Uncheck Enable Kernel Mode Authentication and click
    OK
    Disable Windows Authentication
    Do an IISRESET
    Also make sure that kernel-mode authentication is disabled for the RPC virtual directory.
    Restart Outlook. You should no longer get the prompt for credentials. Test the configuration with Outlook Anywhere clients as well, if you have enabled Outlook Anywhere on your Client Access Servers.
    You may need to repeat this configuration on all Client Access Servers that are enabled for Web-based publishing of Offline Address Book (OAB).

    I have seen this same error before. That issue resolved by Exchange 2010 SP3 RU7.
    So please refer to KB 2961522
    and install Update Rollup 7 for Exchange 2010 SP3 to solve this issue.

  • Outlook 2010 prompt for credential when connecting to Exchange 2013 mailbox

    I have 4 server Exchange 2010 with DAG and one server Exchange 2013, i've migrated some mailbox to the new 2013 server.
    I'm having a problem with some Outlook 2010 that sometimes (not always) requires credential to connect to mailbox in a server Exchange 2013, but only
    when Cache mode is enabled.
    The client ask for credential and dont connect to mailbox until I change in online mode.
    In Online Mode, everything works fine.
    I don't have Public Folders, so the check box Download Public Folder is not selected and the authentication mode is "Negotiate".
    Thanks in advance.
    Elisa

    Hi,
    As far as I know, by default, shared mail folders not public folders are downloaded in Cached mode in Outlook 2010 and Outlook 2013:
    http://support.microsoft.com/kb/982697/en-us
    Please check if there is shared folder in the problematic Outlook 2010 client and try to check if the issue still exists with the same account on other Outlook client.

  • Outlook 2013 keep asking for password

    Hi,
    We having problem where outlook is keep asking for password every time you start outlook.
    Things I tried
     - I have created new outlook profile - still same problem
     - Clear all passwords from password manager - still same problem
     - Deleted the .OST file - still same problem.
     - Always prompt for logon credentials - this is not tick
     - I have tried this
    http://support.microsoft.com/kb/290684
    Only happening on Office 2013 not office 2007
    One thing I did notices when I was debugging the problem.
    When I removed the office and reinstalled the problem went away for
    whole 1 week but then on Monday it start asking for password again which
    makes be thing that they is something in group policy which is causing
    this.
    We are using
     - Windows 7
     - Office 365 (2013)
     - Our emails are being hosted by Microsoft clod
    I don't know what else to try or check.

    Hi,
    Does this issue happen to all clients or a special one?
    Please first check if Logon network security under More Settings on the Microsoft Exchange
    Security tab is set to a value other than Anonymous Authentication.
    In addition, you may also follow this article to troubleshoot the issue:

    You are required to provide credit card details to download apps be it free or paid.
    Nothing will be deducted from your credit card if the app is free.
    There will be a authorizing hold of US$1.00 to verify your account information. It will be credited back to your account later.

    This is a little confusing since you say you have forgotten your password and then the system says you have not entered a password.  Even with an Admin account you must have a password to install software.
    If you are using Mac OS X 10.7 or above, you can change the admin password by restarting holding the Command and R keys, from the menu bar select Utilities, then Terminal.  When the Terminal window opens, at the cursor type exactly:
    resetpassword
    and press Enter.  When the Reset Password window opens, select the internal hard drive, and then the user account.  Type a new password twice, leave the Hint blank, and then Save.  Accept the next dialog that opens, and at the bottom of the Reset Password window agree to resetting the home directory permissions.
    Quit the Reset Password window, go to the apple left side of the menu bar, Restart.
    And you have a new password for your account.

    I've had trouble with my Macbook since the first month I bought it. I've replaced the hard drive 3 to 4 times. Now some programs won't work or shut off by itself. Is it possible to ask for a complete exchange of products?

    This may help you: http://store.apple.com/us/help/returns_refund
    It would appear that you can ask for an exchange but it doesn't specify any time frame... Hopefully someone more knowledgeable can add to this.
    By the way, if you've replaced the drive so many times, perhaps there's something else going on elsewhere.
