Outlook 2013 repeatedly prompts for password when connecting to Exchange Server 2010

I am trying to configure Outlook 2013 on a Windows 8.1 Pro client. The exchange server is 2010 SP1 and works just fine with OL 2010.
When I configure OL 2013, the configuration prompts for a password for the account repeatedly with both NTLM and Basic Authentication chosen. OL 2013 tries to connect and then it disconnects with the password for the account repeatedly prompted. When
the credentials are entered, the prompt reappears immediately.
Might anyone help?
Many thanks in advance
Shuvo

Hi Shuvo,
Please check whether this user can access mailbox in OWA. Please manual setup this account in Control Panel to have a try. Make sure your
Server name and User name are configured correctly. If you are configure the account in internal domain environment, please click
More Settings, set Negotiate Authentication in
Security tab and uncheck Connect to Microsoft Exchange using HTTP in Connection tab.
If there is any updates, please feel free to let us know.

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 *)

*) 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.

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.

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 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:

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.

SharePoint prompting for password when saving word document

Saving a word document back to SharePoint always prompts for credentials.
I am the administrator for a SharePoint farm. We have enabled kerberos, and added the portal to the intranet zone in Internet Explorer by group policy. Most of the time this limits the amount of password prompts our customers see (including viewing the portal
in a browser, and opening documents); however, we are still getting the prompt for credentials when trying to save a word document back to SharePoint.
Here are some details: - SharePoint 2010 - Word 2010 - Kerberos enabled - Portal added to intranet zone in IE - Checkbox for passing automatic credentials enabled
Can anyone help? Is there something I've missed? Is this prompt just unavoidable?

Hi,
Internet Explorer uses the Web Client service when you use Internet Explorer to access a
WebDAV resource. The Web Client Service uses Windows HTTP Services (WinHTTP) to perform the network I/O to the remote host. WinHTTP sends user credentials only in response to requests that occur on a local intranet site.
However, WinHTTP does not check the security zone
settings in Internet Explorer to determine whether a Web site is in a zone that lets credentials be sent automatically.
Click Start, type regedit in the Start Search box, and then press
ENTER.
Locate and then click the following registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WebClient\Parameters
On the Edit menu, point to New, and then click
Multi-String Value.
Type AuthForwardServerList, and then press ENTER.
On the Edit menu, click Modify.
In the Value data box, type the URL of the server that hosts the Web share, and then click
OK.
Note You can also type a list of URLs in the
Value data box. For more information, see the "Sample URL list" section in this article.
Exit Registry Editor.
After this registry entry is created, the WebClient service will read the entry value. If the client computer tries to access a URL that matches any of the expressions in the list, the user credential will be sent successfully to authenticate
the user, even if no proxy is configured.
Note You have to restart the WebClient service after you modify the registry.

Need help with Outlook 2013 connecting to Exchange server(2010)

Hi
I need help with Outlook 2013 and with my exchange server(2010) email account
After setting up account initially emails come in and than after an hour or two stop. My OWA is working fine with no issues. I have even created a forward rule in OWA to my GMAIL account whch works fine
However Outlook 2013 is not syncing messages, have difficulty in sending emails sometimes as it takes too long. In fact the connection also is intermittent. Even if the task bar shows connected to exchange, it seems that is not the case since new emails
and any emails I compose dont work. I have trouble shot the issue with my ISP and email service provide, but they havent resolved the issue I have also done a TraceRoute and that shows no drops or problems to he exchange server.
Can someone please help me resolve this matter so I can continue to use Outlook 2013( running Windows 8.1) in both my computers which have the identical problem
Look forward to a solution soon
Thanks

Hi Angela
Thanks for your message
To answer your questions, please note the following
a) My account is set up in Cache Mode( not online mode)
b) I am the only other user on the account
c) When the connection to the exchange server is broken, I see upon clicking connection tab that there is no information in the box, and when I press reconnect it starts showing "connecting"
d) When the connection to the server is there, it shows connection as "established"
e) Sorry I dont understand th meaning of CAS array in your environment? Can you pls explain
Since yday I have been using Outlook 2010 on desktop and Outlook 2013 on my laptop using Exchange 2013 account. So far all emails are syncing, and I can send emails from both computers. However, I am concerned that the connection can break-off anytime,
as it has done that in the past on both outlook versions. The max time it has worked without any problem is 48 hrs and than after that the same issue of not connection, not syncing and unable to send emails happens
My ISP has checked and there is no network connectivity issues. My email service provider has trouble shot the issue many times, but to no positive results. I have also changed the profile a few times, but the intermittent connectivity problem hasn't
been resolved.
Can you identify the possible causes and more importantly a working permanent solution please
Thanks

How to configure Mailbox Read-Only access for Mailbox's owner on Exchange Server 2010?

I have to configure the Exchange Server 2010's mailbox to only grant Read-Only Access on the mailbox's owners. So they can only allowed to read their messages and cannot modify or remove them. Are there any references or methods to do?

Hi,alexchy8
We can make use of 2 PowerShell commands to achieve this goal.
Add-MailboxPermission and Add-MailboxFolderPermission.
Execute the Add-MailboxPermission command to delegate the read permission at mailbox level.
Execute the Add-MailboxFolderPermission command to delegate the required permissions on specific folders inside the mailbox.
You can read the following article as reference:

Outlook 2010 prompting for password each login to Exchange 2013

We have a new member server w/ Windows Server 2012 and Exchange 2013. User's mailboxes were migrated from an old Windows Server 2003 server w/ Exchange 2003 by creating new empty mailboxes in Exchange 2013 then we exported/imported
.pst files instead of migrating exchange stores. Every time any users opens Outlook, they are being prompted to log in with domain credentials. Obviously I'm clicking on "Remember my password", too. The workstations are all
using Outlook 2010 and on a mix of Windows XP SP3, Windows 7 SP1 and Windows Server 2008 R2 (terminal server with Outlook 2010 installed for remote users). Some users were using Outlook 2010 prior to the migration to Exchange 2013 and some were on Outlook
2007 but upgraded to Outlook 2010. I'm almost to the point of telling the users it's a new "feature" of Exchange 2013. I'm confident that it's not stored passwords or credentials on the workstations, I've removed, deleted, created and
recreated those credentials. I've changed domain passwords and that didn't help either. Any hints, tips or suggestions would be greatly appreciated.

Hi
These settings can be found under your Outlook profile, "More Settings > Connection > Exchange Proxy Settings."
If you have Outlook Anywhere enabled, then you should force all Outlook clients to use HTTP when connecting. Ensure you have "On fast networks, connect using HTTP..." AND "On slow networks, connect using HTTP...". If you
don't, anytime you dock, undock, get a new IP address, refresh your IP address, go to sleep, idle, anything that causes your IP stack wants to renegotiate connective will cause a password prompt to appear, EVERYTIME.

Exchange 2013/2010 Co-existance Outlook Users Always Prompted for Password

Hello,
We are in the process of attempting to migrate to Exchange 2013, but during the migration time, we need to coexist with the two versions. Our outlook clients are a mix of Office 2007, 2010, and 2013. When a user is migrated from 2010 to 2013,
they start getting prompted for their password in Outlook every few minutes. They can click cancel and continue working, but they continue to get prompts for their password. If they click the update folder button in outlook, it updates fine, and
the password prompt goes away for awhile.
Most topics on this state that this is caused by a certificate issue. We have an internally deployed CA, with the Root certificate trusted by all clients. The exchange 2013 server has a certificate that was created by this CA.
I believe that this is caused by OAB (address book) still being hosted on the Exchange 2010 server (with a self signed cert), that is causing the connection to fail. Is there anyway to test this without breaking outlook connections for the users that
are on Exchange 2010? Or is there any other reason that this would occur?
Thanks for any assistance.

Sorry for taking so long to reply, other items came up that rank higher then this migration.
I ran the Test-OutlookWebServices CMD and got this result:
[PS] C:\Windows\system32> Test-OutlookWebServices
Source                              ServiceEndpoint

change the first failing result to the hostname of the

exchange10.company.local autodiscover?

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

Prompted for password when opening icloud mail

Hi,
I downloaded Mavericks a week or so ago and everything's fine except one glitch:
Whenever I open the Mail app, it prompts me to enter my password before retrieving anything. As soon as I enter my password it connects to iCloud fine. Under Preferences (General account tab) there is a password slot into which the password can be entered. But when I do that, and then save the changes, it doesn't retain the information. When I re-open the Mail app, the same prompt re-appears. When I check Preferences, the password slot is still empty.
I also have a pop account separate from iCloud IMAP, and that works just fine. Like it did under Mountain Lion.
Is there some kind of glitch still? I downloaded today the 11-08-2013 Maverick mail update from the App store, but that didn't solve this particular problem. It appears to be related to GMail accounts only anyway.
Any thoughts on how I can get the Mail app to retain my password info for the iCloud account so that I don't have to keep re-entering it?
Many TIA for any hints!
(P.S: My machine is a 2012 15" RD MacBook Pro)

Thanks to both for your replies.
Eric,
Thanks much for that link and the Apple Token workaround. That did the trick!
Thanks a lot for your help.

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.

Kerberos - client has TGT, but prompted for password when accessing share.

I'm getting ready to deploy Leopard to my client base and I'm doing final testing. I have a magic triangle/cylinder of destiny situation, using Active Directory and Open Directory running on 10.5.2.
With a 10.5.2 client bound to both directories, I can log in to the client machine with an AD account, however when I try to connect to a file share, I am prompted for name & password. I checked /System/Library/CoreServices/Kerberos, and I have a TGT.
I'm stumped as to why I'm being prompted when I have a TGT. Any ideas?

Go back to the basics. Time and DNS. Make sure all servers are using the same time server (OD box points to AD domain controller - use ntpq -p to confirm time sync). Make sure forward and reverse resolve works for all servers in the chain. If this all checks out, then look at your AFP service settings or temporarily launch SMB and see if it will issue a service ticket.
You are talking to two different machines but with a common auth point. The first process, getting the TGT is entirely devoted to communication with the AD domain. The KDC in AD agreed that you are who you claim to be and that you can be trusted, thus granting you access to domain resources. The next step is attempting to access a resource on a server that you believe to be part of the trust. In this case, an OS X Server running AFP (assumably). In this case, the OD system needs to be configured as a domain member of the AD environment and all services "Kerberized". This is an area in which Apple needs a little work under Leopard. Tiger was so easy. I've had better luck using dsconfigad's enablesso than with the GUI tools.
However, assuming that you performed all the usual steps, first review the contents of your edu.mit.kerberos file and make sure that Leopard did not rewrite the file and place the OD system in as the KDC. That is all wrong. Next, take a look at your principles by using klist -k. Is the realm information correct? And finally, review the settings in the afp configuration file. The realm information in that file is often messed up if you launch AFP before you have the server bound up properly.
My guess is that the OD box thinks it is the KDC and you will likely need to manually edit the edu.mit.kerberos file and force the file to be static (remove the third and fourth lines). This is common if you joined the AD domain and then promoted the server to OD Master.
Hope this helps
