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.

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:

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 2007 keeps asking for username and password

We have a new exchange 2007 SP1 server but occasionally the outlook clients will ask for the username and password.
Is this a bug or does anyone have a fix?

Hi Edwin,
I have an SBS 2008 install with a similar problem. Using a GoDaddy Cert. Worked fine prior to me running an update to the server. So I think we are getting some where here.
Symptoms
Win Server 2008 (Or SBS 2008)
Exchange 2007
Outlook Anywhere Enabled (RPC-HTTP)
SSL Cert Signed by GoDaddy
Outlook 2007 Clients
Outlook 2007 Clients show Login prompt to the 'remote.example.com' cancel or disable keeps poping it up after some time.
RPC-DIAG shows no problems
Client not configured for RPC-HTTPs
Outlook 2003 Clients unaffected
Things I have tried:
Basic & Windows Authentication on the EWS Virtual Directory in IIS7 on Exchange 07 (SBS 08) box - No Joy
New Profile on Outlook 2007 win XP SP3 - No Joy
New Profile on Outlook 2003 win XP SP3 - Works, but rest of office running Outlook 2007
Disabling Outlook Anywhere - No Joy
Visiting https://remote.example.com on affected Outlook 2007 win XP SP3 Machine - No Error Pages, or dialog boxes, Internet Explorer sees it as a valid Cert
Any KB Articles, or notices?? I have two end-user with a possible third (Business owner) who are getting cranky. :(
EDIT: Found a fix for me potentially via - http://social.technet.microsoft.com/Forums/en-US/exchangesvrdeploy/thread/c1e72d2a-d360-4ff0-b2f5-1a9ae149df18 and http://www.microsoft.com/communities/newsgroups/list/en-us/default.aspx?dg=microsoft.public.exchange.admin&mid=00d4a681-f588-4eed-b4f8-5c3645e7376c&sloc=en-us

I had an issue similar to this. Win2k3 Ex07. All of my Outlook 2007
users were getting prompted over and over for the username and
password. It wasn't checking the certificate that they had installed
via internet explorer. To fix the problem, I opened IIS on the
Exchange server and checked the following directories under the
default website (the root site(default web site), oab, autodiscover).
Under the directory security tab, click Edit in the Secure
Communications section. I had the require SSL checked and the 128bit
encryption, but under Client Certificates, it was set to ignore. Once
I changed that to Accept for each of the folders, stopped and started
IIS, I stopped being prompted all the time for credentials. Hopefully
this will help someone in the future.
Just confirmed fixed for client!!!

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.

Firefox will not recognize web pages with .aspx suffix, keeps asking for a program selection to open the file.

Searched for "st davids austin" on Google. In results clicked on listing for St David's Hospital North Austin. Apparently the site is written in ASPX and FF will not open it. It keeps asking for me to make a program selection to open the page. When I select FF as the program it just loops back and asks the same question again.

1. That is caused by a few different Bugs in Firefox 3.6 and earlier versions. It looks like it was fixed for Firefox 4.0.
2. Firefox doesn't go by the "system default printer". Firefox goes by the last used printer in Firefox as being the "default" in Firefox. It will remember the "last used in Firefox" and will use that printer until you switch to another printer and then remember that one.

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 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.

W2008R2 trust with W2012R2: Synology diskstation asks for credentials

Hi,
I have a 2 way trust between a Windows 2008 R2 and a W 2012 R2 server which works fine.
I can access shares on both sites without a problem. Then I have this Synology diskstation which is added to one of both domains. I can access the shares of it in 1 domain, but in the other domain I'm asked for credentials.
Please advise.

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.

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?

ITunes keep asking for credentials

Hi all, I have an IronPort S170, with latest version and updates.
We have a lot of users using itunes to sync Apple devices, the problem is that it allways asks for user & password, several times (really annoying). Can anybody help me solving this issue?
thanks a lot
Best regards.

HI Gonzalo,
I assume you're using NTLM SSO. Pending on you configuration this auth popup is created due inability to authenticate via NTLM for the specific request. It seems there are currently known problems with iTunes and NTLM auth. I found records on apple support communitate reporting version 1.6 of iTunes no longer being able to proper authenticate via NTLM. As workaround you could use e.g. IP surrogates which will keep the users IP authenticated once the first request has been authenticated, e.g. via Internet Explorer. By this iTunes will not require to authenticate again. Also your Domain Controller will be happy to have less auth request.

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 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.
