Outlook 2010 keeps prompting for credentials

Hello,
I have just about every user experiencing an issue with Outlook 2010 where Outlook keeps prompting for credentials.  This has been happening ever since recent Microsoft Office updates that rolled out last week it seems. All my users still have connection
to the exchange server and can send/reply just fine.  Issue occurs on both 32 bit and 64bit versions.  This prompt will appear every few seconds and is becoming a nuisance for all my users. 
I have attempted the following with no resolution:
- removed credentials from credentials manager
- ran Outlook in safe mode
- ran repairs on Office
- completely removed and re-added users Outlook profile (profiles are manually configured)
- made sure Office is up to date
- configured Outlook account on freshly imaged PC

Hi,
For this issue, you can first try some suggestions in this forum content:
Why does Outlook keep prompting for password
Especially try NTLM Authentication to check the result.
We have received some report about this issue since the February 10, 2015 update for Outlook 2010 (KB2956128). If you have installed this update, please note we have realized this issue and once there is any update, I'll let you know.

It's recommended to download and install
Configuration Analyzer Tool (OffCAT), which is developed by Microsoft Support teams. Once the tool is installed, you can run it at any time to scan for hundreds of known issues in Office
programs.

  • Outlook 2010 keeps prompting for password

    Hi,
    We use Exchange 2008 and Outlook 2010. For some reason, Outlook 2010 keeps prompting for password. My use entered the password and checked "Remember Password" box, but next morning when he logged in, he still got the prompt.
    I removed the Outlook credential for Outlook listed under Password Credential in Control Panel, but still no help.
    Please advise!
    Thanks in advance!

    Hi Grace
    1. Open Outlook 2010. Click File>Account Settings>Account Settings. 
    2. Click the E-mail tab, click the Exchange Online mailbox, click Change…
    3. Click More Settings…. Click the Security tab, make sure the Always prompt for logon credentials box is unchecked. 
    Please mark it answer if it helps you solving your problem

  • Outlook 2010 keeps asking for credentials

    Hello,
    We have a Exchange 2013 server with outlook 2010 clients wich constanly ask for credentials.
    even with the option save credentials on.
    The Exchange servers are hosted and the clients are not part of a domain and use Outlook Anywhere.
    Outlook 2013 clients do not have this problem.
    I tried several things:
    -new profile
    -rename ProtectSystemProider folder
    - dword registry Savecredentials
    - removed ProtectSystemProvider registry key
    - Removed or edited credential manager accounts
    We have this problem on serveral Windows 7 clients and Remote Desktop Server 2008 r2 sessions.
    Hope anyone can help me.

    Hi Cris,
    Please try to clean up the cached credential in your computer. Then fill in with the format of UPN when it prompted for credentials next time and check the Remember my credential to save it. About how to remove cached credentials, please follow these steps:
    1. Launch the Credential Manager from Control Panel > All Control Panel Items > Credential Manager.
    2. In the Generic Credentials section you’ll see a setting for [MS Outlook] which will include your SSO details. Click the downward-pointing arrow to the right of that value.
    3. In the expand details, click Remove from vault. Then Outlook will no longer have a stored copy of your password.

  • Outlook 2010 keeps prompting for password every morning

    Hi,
    We run Exchange 2007 on Windows server 2008. All SP and updates are up to date.
    About a month ago, two users got prompt for user credential in Outlook every morning, but other users in the domain are fine. Below are what I have tried but no help.
    1. Deleted user credential for Outlook in Credential Manager
    2. Recreated Outlook profile
    3. Disjoin and rejoin their computers to the domain
    I can repeat the problem on another computer with the user's account log in.
    The problem only happens in the morning, once the user entered the credential, Outlook starts to update new email and it will be fine for the rest of the day.
    Only two users have this problem. I can't figure out if they have anything in common. Since I can repeat the problem on another computer, I assume this problem should be related to user account.
    I need help!
    Thanks in advance!

    Hi,
    As per the information and details provided by you, to solve the Outlook 2010 password problem, please follow these steps: -
    Firstly, you try to
    change the profile.
    Open Control panel/Mail/Select the profile and click Properties.
    Select the mailbox and click the
    Change button.
    When inside the profile you will see tabs at top for
    connection and security.
    Please make sure you have selected
    Negotiate authentication, and have unchecked the box that states
    Always prompt for login credentials.
    Then check if you are using
    HTTP to connect with exchange, if so uncheck this and apply the changes.
    Close Outlook if open and reopen Outlook.
    I hope this information will be helpful for you.
    Thanks and regards
    Shweta@G
    Hi Goyal,
    Thank you very much for your reply. The Outlook settings are the same as you described. We do use HTTP to connect to Exchange. I unchecked it and see what happens tomorrow. but just FYI. All Outlook has the same settings with HTTP connection checked. Only
    two specific accounts have the credential issue.
    Will update you tomorrow.
    Thanks,
    Grace

  • Outlook 2007 keeps prompting for credentials

    I've seen so many articles on this and it still plagues me.  I've had enough.
    I am in a pure Exchange 2007 environment.
    SCC Mailbox Server
    Hub & CAS are on a different Server but together.
    Outlook 2007 is installed on my workstation.
    I setup a profile using the auto-discover process (default) and I am prompted for a passwrod to my hub and CAS?  I enter in the CORRECT credentials and I am prompted again.  Remembering months ago that I was unable (or unwilling) to resolve this annoyance I hit cancel and chose to set it up manually.  this worked using the Exchange Clustered Mailbox name.
    As soon as the profile is setup and I am into Outlook I'm prompted again! wow, what is this? I enter in the CORRECT credentials AGAIN and i am repeatedly prompted.  after hitting cancel 30 times i continue on with my work. 
    ..but then I close and re-open Outlook, same process all over again.  the Windows prompt is prompting me for creds on domain.com (my domain)  what is going on here.  i have not even had a chance to configure (break) anything....is this default behaviour for exchange 2007/Outlook 2007?  I know I am missing something here but I just can't seem to get around this.
    I have tried most MS KB articles out there (can't find the links to provide)
    Yes, I'm on the Domain
    Yes, I have decided to set it up manually and chose not to use Auto-discover, which to me at this point is a terrible feature. 
    Yes, my bottom right corner of Outlook 2007 says "Online with Microsoft Exchange"
    Outlook 2003 clients do not have this problem which tells me this is something in Outlook.  I can uninstall Outlook 2007 and replace it with Outlook 2003, same workstation, same user logged in with no problems.
    Whats going on here?
    thanks

    i solve this problem with this
    Kernel authentication Mode
    If you have all the above configured and you are still experiencing problems then the following procedure will more than likely fix it for you. It has been working a lot for me lately and also for people asking questions on Experts
    Exchange.
    In Internet Information Services (IIS) Manager locate the Exchange virtual directories, if you are using Small Business Server 2008 these will be under the SBS Web Applications website, if your not using SBS then they will be under
    the Default Website.
    The virtual Directories you are looking for are:
    Autodiscover
    EWS
    RPC
    OAB
    In turn highlight each of these virtual directories and double click the Authentication icon on the right hand side. Right click on Windows Authentication and select Advanced Settings. Place a check box in the box for Enable kernel-mode
    authentication. Do this for each virtual directory listed above.

  • Exhcnage 2013 Migration - User keep keeping prompted for credentials

    Hello,
    I am migrating all on-premise exchange 2010 SP3 to Exchange 2013 SP1. I am testing mailbox migrations, each mailbox that gets moved to 2013 the user keeps getting prompted for credentials. I have read several posts in the forums yet none which solve my problem.
    Can someone point me in the right direction. All 2013 setting are currently at default.

    Thank you for your help and your quick response.
    Here is the autodiscover test. When I move the mailbox to 2013 its picks up the 2013 URL. In this output mail.myserver.com is the hostname of my 2013 cas.
    Also noticed the following in the server field under account settings.

  • Outlook 2013 continually prompting for credentials on new domain

    Greetings,
    I first posted this in the Office365 community forums and was directed here.
    We are experiencing an issue where Outlook 2013 (Office365 install) is prompting for user credentials every time it is opened, despite checking the option to remember the credentials. So far we've tried a number of troubleshooting steps, but nothing
    has resolved the issue. The issue is happening to multiple users on multiple computers.
    We are running:
    Outlook 2013 (32-bit) (Office 365 install)
    Windows 7.1 Professional (x64)
    Computer is domain joined (Server 2012 R2 Domain Controllers)
    Mail is hosted on Office 365
    We've tried:
    Clearing the Outlook and Office credentials from Credential Manager.
    Removing the mail profile and the saved credentials from Credential Manager, then re-adding the mail profile.
    We've tried adding the mail profile with both a manual configuration of the server settings and allowing Outlook to automatically configure them.
    Ensuring that "Always prompt for logon credentials" is unchecked.
    Setting "Always prompt for logon credentials" to disabled via registry (see
    http://support.microsoft.com/kb/2984912)
    Confirming that Autodiscover is able to connect (http://www.microsoft.com/en-us/showcase/details.aspx?uuid=e8db028a-06f4-45fb-aff1-e8ac896d29c5)
    Deleting the Autodiscover.xml file so that it is recreated
    Doing an Online Repair of Office 365.
    Reinstalling Office 365
    Recreating the user's Windows profile.
    Ensuring all applicable Windows updates and Office updates are installed.
    Changing Proxy Authentication from Basic to NTLM (will not connect with NTLM)
    The machines this is occurring on are on a new domain that we are in the process of setting up. The user accounts are still on the old domain. Cross-domain trusts are set up in both directions and all other services are working fine. GPO settings across
    both domains have been set up to be identical. The issue occurs on computers that were built directly on the new domain as well as computers built on old domain and migrated over. Machines that are not domain joined or are still on the old domain are not experiencing
    the issue.
    If any of you could provide any insight or other steps that we could try I'd greatly appreciate it.

    Hi,
    For the issue that Outlook keeps prompting for password, I usually suggest users follow the steps in this article below, but apparently you have tried almost all the steps:
    Why does Outlook keep prompting for password
    I've seen some similar issues that were caused by an old "network driver", which for some reason caused a wrong server name to propagate up from the network layer to the application layer. Updating the network driver would fix the issue, I'm
    not sure if this works in your scenario though.

  • Outlook 2013 Continually Prompting For Credentials

    After migrating to Office 365 & installing Pro Plus 2013, Outlook 2013 (32-bit) continues to prompt for credentials even though it shows the mailbox as connected to Exchange.
    To stop this prompt, I've done the following:
    Removed Outlook credentials from credential manager
    Removed/recreated Outlook profiles & renamed "outlook" folder found at C:\User\"username"\AppData\Local\Microsoft\ to "Outlook.old" so Outlook will recreate the folder upon restart.
    Checked Security tab of "more settings" of the mailbox to make sure "Always prompt for logon credentials" isn't checked.
    Please someone give me guidance as to what else the issue could be.

    Hello,
    How did you set the Logon network security under More Settings on the Microsoft Exchange
    Security tab? Please make sure it's not set to a value other than
    Anonymous Authentication.
    To verify this, please follow these steps:
    1. Launch Control Panel.
    2. In Control Panel, locate and click
    Mail.
    3. Click Show Profiles, select your Outlook profile, and click
    Properties.
    4. Click E-mail Accounts, select
    Account Settings and on the E-mail tab, click Change.
    5. In the Change Account dialog, click
    More Settings.
    6. In the Microsoft Exchange dialog, select the
    Security tab.
    7. From the Login network security
    dropdown, select Anonymous Authentication and click
    OK.
    8. Click Next and click
    Finish, and then click Close on the Account Settings dialog.
    9. Click Close on the
    Mail Setup dialog, and click OK to close the Mail control panel.
    Please let me know the result.

  • ABAP consuming Web Service in HTTPS keeps prompting for credentials

    I have a Share Point Web Service that I want
    to call in HTTPS from ABAP
    in an ECC 6.0 SAP_BASIS 700 SP 30 system. The
    following steps have been
    executed:
    BASIS work completed –
    SAPCRYPTOLIB, HTTPS Activation, profile
    parameters, STRUST certificates
    I have created the Client Proxy in SE80 for the SharePoint WCF Web Service
    The Logical Port was created in SOAMANAGER
    The issue I have is when I test the process using SE80 sometimes it will prompt
    for credentials, sometimes it won't. The behavior is very sporadic, I
    can run it once and it prompts then the second time it doesn't. This is
    especially true after a restart of the system. The user and password
    are on the RFC destination under consumer security tab.
    Any suggestions why the prompting for
    credentials?

  • Outlook 2010 + Exchange 2010 keeps asking for credentials - Please Help!

    Hello All,
    Recently after a Windows Update + restart of my Exchange Server I'm having an issue with Outlook 2010 where it continually asks for credentials. Every 5 minutes or so the credentials popup appears and either typing your password or clicking cancel will make
    Outlook work as expected again until the next popup, frequency of popups is about 2-5 minutes give or take. I am using Exchange 2010 on Server 2008 R2 and aside from the popup everything is working as expected. This seems to be effecting almost all users.
    Some things I've tried already include:
    - Removing any saved credentials on computer
    - Removing and recreating Outlook Mail Profiles
    - Running "Set-AutodiscoverVirtualDirectory -Identity 'autodiscover (default Web site)' -WindowsAuthentication $true -BasicAuthentication $false" in shell to disable basic authentication for autodiscover
    - Running "get-outlookanyhwere | set-outlookanywhere -ClientAuthenticationMethod NTLM -IISAuthenticationMethods NTLM" in shell to ensure that outlook anywhere and IIS are using NTLM authentication
    - Ensuring that the OAB folder permissions are set to allow Authenticated Users to Read/Execute
    Anyways, if anybody has additional suggestions for me I'd very much appreciate them. Many users are using the Web App for the time being (with no issues) since the credentials popup is too annoying for them.

    So I made sure that all of my authentication methods match the settings you linked me and then recycled the app pool you mentioned but am still having the issue.
    One thing I noticed is that if a user experiencing the problem types their password into the credentials popup it will keep popping up continuously but if they hit cancel it says "Needs Password" where it would normally say "Connected to Microsoft Exchange"
    and if they simply click once where it says "Needs Password" then all of a sudden it switches to "Connected to Microsoft Exchange" again and they no longer see the popup until Outlook is restarted.
    Just to verify I have the proper settings now this is what shell returns:
    [PS] C:\Windows\system32>Get-WebServicesVirtualDirectory | fl *auth*
    CertificateAuthentication     :
    InternalAuthenticationMethods : {Ntlm, WindowsIntegrated, WSSecurity}
    ExternalAuthenticationMethods : {Ntlm, WindowsIntegrated, WSSecurity}
    LiveIdSpNegoAuthentication    : False
    WSSecurityAuthentication      : True
    LiveIdBasicAuthentication     : False
    BasicAuthentication           : False
    DigestAuthentication          : False
    WindowsAuthentication         : True
    [PS] C:\Windows\system32>Get-AutodiscoverVirtualDirectory | fl *auth*
    InternalAuthenticationMethods : {Basic, Ntlm, WindowsIntegrated, WSSecurity}
    ExternalAuthenticationMethods : {Basic, Ntlm, WindowsIntegrated, WSSecurity}
    LiveIdSpNegoAuthentication    : False
    WSSecurityAuthentication      : True
    LiveIdBasicAuthentication     : False
    BasicAuthentication           : True
    DigestAuthentication          : False
    WindowsAuthentication         : True
    Do you have any additional suggestions that I can try? From what I can tell my authentication methods all match the default settings now.
    Edit: As soon as I changed EWA to just Basic Authentication as it says in the linked default settings I would get an error when trying to browse to the EWA that said "Outlook failed to initialize" and re-adding the Windows Authentication, then running iisreset
    fixed the issue. Therefore EWA is the only service with non-default authentication methods now.

  • Outlook 2010 - new prompting for password

    After installing Office 2010 Beta and working fine for about a month and a half, Outlook started prompting for a password.  The machine is on the domain so the Outlook did not prompt before.  If you cancel the prompt, everything seems to work fine.  This happens on both Windows 7 64-bit and Windows XP.  It started happening to all known users on Office 2010.  The problem started on January 8, 2010.

    I have searched all over for a solution to this crazy problem and some of them highly technical and poorly explained and were for outlook 2003 and 2007.  Finally I found this less than 2 minute fix that works.    http://www.howtogeek.com/howto/windows-vista/fix-for-outlook-2007-constantly-asking-for-password-on-vista/ 
    This is not my fix but glad to pass along something that actually works.  Give Kudos to the "how-to-Geek" and post in other forums to help out all your frustrated friends.
    1.  Close outlook!
    2.  go to my computer and then paste this into the address bar.          %userprofile%\AppData\Roaming\Microsoft\Protect
    3.  rename the very long file name S-1-5......etc by appending "-old" to the end of the existing file.
    4. now re-open outlook and you may be request for your password.  If so enter it and check the remember password box
    5.  now go back to %userprofile%\AppData\Roaming\Microsoft\Protect by searching in windows explorer or my computer and you should see the renamed long named file
    and a brand new long named file.  
    This should work for you.  If not, then do a shut down and reboot a time or two.  Then try reopening outlook 2010 and your problem should be fixed.    Save
    this link:  http://www.howtogeek.com/howto/windows-vista/fix-for-outlook-2007-constantly-asking-for-password-on-vista/ 
    because this problem is likely to recur sporadically because of microsofts pushed updates that cause more problems than they solve.  Turn off automatic updates so MS cannot keep screwing up your system and snooping.
    This fix was explicit for Vista but worked fine for me on Windows 7 64 bit running outlook 2010.  Post your results to see if it works for others please.  I know everyone is tired of chasing their tails on this problem and even posted fixes have
    been so vague that you need to be a software engineer to follow them.  If you have other fixes for this I know everyone would appreciate people posting all the steps from the beginning to end and assume that we know nothing at all.   Post all the
    paths and explanations in simple terms please.
    I hope this helps.

  • SBS2008 in combination with Outlook 2013 keeps asking for credentials

    I've got a SBS 2008 server with windows 7 pro clients.
    Some of them use outlook 2010 and some use 2013.
    The users which use the 2013 version has a problem with saving of the credentials.
    Every time they start outlook 2013 they will be asked for credentials and some of them 5 times before it starts.
    The weird thing is: if you click ESC to close the screen that asks for the credentials, outlook still connects to the mailbox.
    Is there someone who can tell me how to fix this problem.

    Hi Willy-Billy,
    Any update? Would you please let me know the current situation of this issue?
    In addition, would you please let me confirm something more?
    Please check if problematic user accounts access mailbox correctly via OWA.
    If you create a new outlook profile for a problematic account, will encounter the same issue?
    As mentioned in the link that Robert provided, please check if you enable
    Always prompt for logon credentials setting in Outlook 2013.
    If you enable this setting, please uncheck and monitor the result.
    Meanwhile, please remove the old credential in
    Credential Manager, then add again. Please check if this issue still persists.
    Please run
    SBS 2008 BPA to collect SBS configuration information and analysis. Then check if you can find some clues.

  • MAPI over HTTP not working correctly, Outlook 2013 clients prompting for credentials during profile creation or opening depending on security of virtual directory

    ENVIRONMENT
    -1 Exchange 2013 SP1 CU7 server with all roles that is also a hybrid server with Office 365 tenant, mailboxes are all on premise only LYNC online is being utilized right now.
    -Exchange 2013 public folders
    -Mix of Outlook 2013 SP1 and Outlook 2010 SP3 clients all fully update to day as of Feb 2015
    Outlook anywhere is working perfectly across all clients both internally and externally using autodiscover.  Both Outlook 2013 and 2010 clients can open the program and create a profile automatically via autodiscover and no additional logon prompts
    are seen.
    We set the internal and external mapi virtual directory URLs to a valid URL that also matches the Exchange 2013 SSL certificate.  We set the security to ntlm, negotiate on the mapi virtual directory.  We reset IIS and enabled mapi over http in
    the org config.  We run in to problems here.
    Outlook 2010 clients appear to be working fine.  We can create a new profile and open and close Outlook without any logon prompts and verify that MAPIHTTP and Negotiate are used to connect to Exchange.
    Outlook 2013 clients are having problems.  As soon as we try to create a profile it says your administrator has made a change that requires you to restart outlook and then a windows logon prompt appears. If we authenticate Outlook will open and connect.
      This logon prompt should not occur.    We can confirm that it is connecting via MAPI HTTP and Negotiate.
    If we set the mapi virtual directory to NTLM only then a logon prompt also appears during every open of Outlook 2013.  We can confirm that it is trying to connect with MAPIHTTP via NTLM in the outlook connection test screen.
    I do not understand this behavior by Outlook 2013 which was supposed to be designed with MAPI HTTP in mind.  I would think the same issues would occur with Outlook 2010 but they do not.  I am not sure how to resolve this and I am looking for help.

    I have the same problem. Exchange and Outlook are both up to date. After creating a new profile Outlook prompts for username/password. A lot of users also get this prompt while
    working - the profiles have been "migrated" from Exchange server 2010. <o:p></o:p>
    Niko, as i can see in your screenshot you do not have Mapi over HTTP enabled. Why? You can change settings in the security tab – if you have Mapi over
    HTTP enabled all options are grayed out (please correct me if I
    am wrong):
    This is a very annoying thing – does anybody else have the same problem?
    Any suggestions on this?

  • Outlook 2013 Constantly Prompting For Credentials - Exchange 2007 - Small Business Server 2008

    Hello, I am having a problem using Windows Small Business Server 2008 and Exchange 2007 with Outlook 2013. The issue is that a credentials box appears in Outlook 2013 when using there exchange account whilst connected to the domain. The box will randomly
    prompt for user credentials, once the user credentials are entered it will either pop back up again and if you enter the details in again it will continue to pop up for around 4 or 5 times before accepting the credentials. It will then pop back up within 15
    minutes and do the same thing, if you click "Cancel" on the box it will also go away and remain connected to exchange however a popup in the bottom right will appear asking for a password even though you can send / receive from the mailbox.
    I have looked into this issue for hours and hours and still can not find a resolution, I have tried re-installing Office 2013 and re-creating the Outlook Profile as-well as as the Windows 7 Profile. I have checked through all the SSL certificates in IIS
    and everything appear to be correct.
    Is this a common issue? Is there anything I can do to further diagnose or fix this issue without having to try to re-install both the server and machine?

    Hi James_wilson,
    Any update?
    Just additional, would you please let me know whether have installed all updates for Outlook 2013? If hasn’t, please install and then monitor the result.
    Please also check if you enable
    Always prompt for logon credentials setting in Outlook 2013. 
    If you enable this setting, please uncheck and check if this issue still persists. Meanwhile, please remove the old credential in
    Credential Manager, then add again. Then monitor the result
    By the way, please run the Exchange BPA on the SBS 2008 server and check if can find some issue.
    Hope this helps.

  • Outlook clients get prompt for credentials

    I have get the following strange problem that when the Exchange server restart and get back on-line my outlook clients all get prompt to enter their credentials. If they open and close Outlook it works until there is a lost in communication between Outlook
    and Exchange. Everything work until a week or two ago and suddenly it just start to happen. All I did was to reset a few users passwords, but that was not a issue at that time and now sudden it seems to get worsted. 
    We run Exchange Server 2013 CU5 on Windows 2012 everything patched with Windows 7 Professional Clients either Outlook 2010 or Outlook 2013 everything patched.
    Any advice?
    Thanks.

    Hi,
    Based on my experience, the credential issue has many reasons: improper authentication method, access public folder, connectivity issue, performance and so on.
    Thus, to narrow down the cause, I'd like to confirm the following inforamtion before we can go further:
    1. Does the issue happens on all your clients? randomly or regularly?
    2. Check the connection status when the credential appears.
    3. Check the authentication method of Outlook Anywhere: get-outlookanywhere |fl *auth*
