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*

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.

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.

Lync 2010 & 2013 Co-existence, After Moving fileshare clients are prompting for Credentials for RGS

Hello,
I am in middle of migration from lync 2010 to 2013. At the moment both enviroments are in Co-existense state, Got pools on both enviroments, however all users are moved to 2013 pool already. Also edge has been migrated already to 2013, and it seems to work
fine (except mobility).
Last Friday I decided to move the lyncshare from old server to new one (both servers were using same lyncshare on old server). I was using this guide: http://technet.microsoft.com/en-us/library/gg195742%28v=ocs.14%29.aspx and all were working pretty fine.
When about hour was passed after last steps, problems started to occur. All clients are asking for credentials to RGS, nowhere else. Entering credentials won't help, prompt appears again. If i cancel the prompt, lync works, but shows error in lower right corner:
Cannot synchronize addressbook (or something similar). Checking connection configuration from client shows that EWS is not deployed, which has been deployed.
I have also checked twice that the permissions are right on lyncshare.
Where should i start to look a solution for the problem ? Seems bit odd that moving a share kinda breaks whole system.

Hello,
Apparently the problem this time is not the Lync, but Exchange. As we are having Exchange migration on the same domain at the same time, I were troubleshooting the problem more, and found out that Lync Client is configured to use EWS Internal & External
url in "https://server005.domain.local/ews/exchange.asmx" , but when opening the url i receive the followin page:
and syntax is: svcutil.exe "https://server014.domain.local:444/EWS/Services.wsdl" , so If i understood right, the problem is in exchange, not in Lync at the moment.
About errors in FE Event Viewer, There is one error repeating often, have not found a solution yet.

Getting Prompt for Credentials When Opening InfoPath 2010 Form in Sharepoint 2010

I have a domain user who runs Office 2010 x32 and uses a Sharepoint 2010 site daily. Lately a specific page on that site has been randomly giving prompts for credentials when opening existing documents and creating new ones. The process can be most easily
replicated by opening the new document template in Infopath by going to Documents -> New in the ribbon bar of the SP page. Most of the time the Windows credentials for the user are passed to Infopath/Sharepoint automatically (which is normal), but on the
fourth or fifth attempt to create a new form, the prompt appears. The user can still enter the credentials and open the blank template form, but a prompt should not appear. The user is also the administrator for that page, so I'm thinking it's not a permissions
issue.
The user is running IE 9 on Windows 7 Pro x64. I have performed the following:
Reset advanced IE settings and all user cache data
Cleared cached Sharepoint credentials in Windows credential manager
Re-applied group policy for the machine using gpupdate /force
Logged in with a clean temporary profile
Logged in to another domain account using the user's Sharepoint credentials
Cleared Infopath cache
Re-installed Office 2010 x32
The problem only occurs only on this particular machine. There are no Sharepoint or authentication-related errors or warnings in the application and system event logs. There are also no error messages on-screen when the prompt appears. I also considered
the possibility of this being a performance related issue in the case that maybe Infopath was taking too long to start, causing the credential pass-through process to time out and fall back to a prompt. I ran disk cleanup, deleted some temporary files, and
checked for excessive CPU/memory load. I didn't find any issues and doing these things did not help.
I'm convinced there is another setting somewhere in Windows that is causing this. Interestingly it always happens after four or five attempts, never the first time. Can someone point me in the right direction?

Hi Titan, this sounds like an IE security setting issue. Things to do:
1. In Internet options>Security>Local Intranet, make sure "Enable Protected Mode" is not selected.
2. Under Sites>Advanced, add https://*.sharepoint.com (and make sure "Require server verification..." is not checked).
3. Under Security>Custom Level, scroll all the way to the bottom and make sure "Automatic logon with current user..." is checked.

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.

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.
Best regards,
Justin Gu

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.
Thanks

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 Anywhere Prompts for Credentials only for Outlook 2010, not Outlook 2013

I'm having a heck of a time with this one. We have Exchange 2010 on premise, with our filtering through EOP. Clients that are using Outlook 2010 Professional Plus are continuously getting prompted for credentials when off network and relying
on Outlook Anywhere.
I've read many threads about configuring credential manager appropriately for the internal domain and our external domain. I can get them to authenticate just fine, and email flows, but they continue to be prompted everytime they connect again.
Here is the kicker: When I install Outlook 2013 on the same computer, outlook anywhere functions just fine, no problems, no authentication prompt.
Like I said I have read a plethera of articles and threads about this, I have gone through all settings on Exchange, our edge server, our firewall, our certificate. The MSSTD string matches our "Issued To" string. NTLM authentication
is configured on both the client and the server. Appropriate settings are configured on the firewalls.
Anyone know why Outlook 2010 would have this problem, but not Outlook 2013 on the same computer, same user, same mailbox database?
Thanks in advance!!!

I'd still Echo Ed's original question.
Do you have Outlook 2010 patched up? At this time you need to be on SP1, and SP2 by October the 14th.
Also I expect you to have a recent update ontop of that as well.

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.
<?xml version="1.0" encoding="utf-8"?>

Shared folders (Windows file shares) show access denied and do not prompt for credentials

Scenario:
Like other admins, I log on and work as a 'standard user' (usera) with no admin rights anywhere in the domain, to perform admin tasks I have another account (userb) which I authenticate with as and when required. userb has been allocated/delegated permissions
as required.
Problem:
When trying to connect to shared folders on servers (2008 R2) using a UNC patch via Windows Explorer (Win 7 Ent.), I see an access denied error and do not get an option to supply alternative credentials.
If I try to connect to the admin shares on the same server (\\server\C$ or \\server\e$) I get an access denied message AND get prompted for credentials. I supply my admin account and gain access as expected.
If I check share and storage management when attempting to connect, I see that Windows is trying to connect me to each share as usera (which has no access). I understand why I get access denied at this point, but not why it can't just prompt me to supply an
account that does have access. When trying the admin shares I also see the usera account, but I get a prompt to supply a user who does have access.
Share permissions on the folders are for example 'Everyone' Full Control. NTFS permissions are 'userb' has modify (read, execute, list, traverse etc) via a 'Server Admins' AD Universal security group.
Note: If I do a NET USE from CMD and use the /USER switch, I can access the shares fine. But this is not great for accessing shared folders on the fly from various computers.
How can I get the other shares on the server to prompt me, rather than just say access denied?
Many thanks.

Kerberos authentication prompting for credentials in Sharepoint 2013

Hello all,
I think I’m a bit confused on what I should expect out of Kerberos and sharepoint.
Following the steps located in
http://blog.blksthl.com/2012/09/26/the-first-kerberos-guide-for-sharepoint-2013-technicians/ , I’ve setup Kerberos in my Sharepoint 2013 environment. My hope was that configuring kerberos authentication would solve the issue of users being prompted for
credentials when they access sharepoint. I know that one way to address this problem is to tweak the IE settings by adding the site to the local intranet or trusted zones, but am I wrong in thinking that Kerberos should also authenticate the user on to the
site? Here’s my situation:
Previously, I had our sharepoint URL in the trusted zone and had IE set to pass my credentials through, and that worked. After configuring Kerberos, I can see the tickets on my system using klist and the security log on our web front-end shows that I authenticated
using Kerberos.
However, if I then remove the sharepoint URL from the trusted zone in IE, I still get prompted for credentials. If I cancel the credential prompt, I get a 401 error and the security log on the server shows a NTLM login attempt.
As soon as I put the URL back in the trusted zone, I can access the site and the server log shows a Kerberos authentication.
I’m I wrong in thinking that if Kerberos was working properly then I shouldn't need to have the URL in the trusted zone?
Thanks
Bill

Thanks for the quick reply, Alex. At least it’s good to know it appears to be working as designed.
Thanks again,
Bill

Windows XP Machines Always Prompt for Credentials (Exchange 2013, Outlook 2010)

I am running Exchange 2013 on Server 2012 Datacenter (VM). Windows 7 clients with Outlook 2010 work fine. Windows XP clients with Outlook 2010 prompt for credentials (user name and password) each time Outlook is started, and checking the "Remember
my password" box does not prevent this from happening the next time. The "Always prompt for logon credentials" checkbox on the "Security" tab of the "More Settings" section of the Exchange account is not checked. I have found a myriad of posts
with similar issues, but they all seem to have to do with SBS/Exchange 2007, and I haven't come across something that works as a solution for me. One suggested certificate issues, and I was having certificate security warnings, but I got that resolved.
I am hopefuly that the fact that this only happens on Windows XP will be telling.

Outlook prompts for credentials when left open for multiple days

Hi,
We have a system setup with Outlook 2010 on it (connected to Exchange Online) and a 3rd party piece of software that interacts with it to send and process incoming messages. This system remains up and running with no user interaction indefinitely.
The problem we're having is that after about a week or so, Outlook stops processing emails and prompts for credentials. Outlook has been set to remember the password (and it's not an issue of the password being expired). Is there a setting to stop
this (I'm assuming it's Exchange that's the culprit)?

First of all exchange online is not the culprit in this case. Can you check what method you're using to authenticate the user? ADFS? DirSync with Password Sync or cloud identitiy? Once checked please make sure that the time interval setup for login prompt
once the user account is inactive is setup unlimited for this user. Thanks.
Kindly Mark this as answer if found helpful. Thanks.

SharePoint prompts for Credentials

Hello,
Users are experiencing pop-up message prompting credentials when they use SharePoint 2010 . Users who use the Windows Explorer view often get the most prompts, but everybody is getting prompted for their username/password. Some get prompted more
than others. Others may not see a prompt for a few days or a week or so, but others will see it nearly every day. Users enter their username and password, but will be prompted later on in the day.
The site is trusted in IE in the intranet zone
Automatic logon only in Intranet Zone
Users using IE 10/11
Clients are using Window 8/7
Web Client service is running on the client desktop
Desktop Experience is enabled
SharePoint is using NTLM
Users are using the FQDN to reach sites, like
http://sharepoint.domain.com
Could be a problem with NTLM? Could there be a problem with DNS? Are security certificates being lost? Is the SharePoint server losing connection with a domain controller? Where can event logs be found to track who is being prompted and when
authentication is lost with a user's session? On the SharePoint server, entries for this event are not being created in Windows application event logs and SharePoint logs. Any suggestions would be great.
Paul

Cleraly the authentication information isn't coming through to the Server automatically. The normal cause of this you've already addressed, the Trusted/Intranet zone and automatic credential passing. The second most likely cause is the same but there's an
error in your configuration, check it from the basics once more (fiddling with the settings in there).
You can have issues if you've set the SharePoint site up as a C record instead of an A Host entry in DNS but i've only seen that with Kerberos and it had quite different symptoms.
Certificates are always a potential problem but it's not the first place i'd look. Check the windows security logs on the WFE server to see what authentication is happening on the server when your users connect.
To eliminate DNS as a cause try connecting to the server using an entry in a client computers host file.
