Outlook Password Prompts events

Few mailboxes (not many) where reported with outlook password prompt and I'm trying find events related to outlook password prompts..
Need help on, where to find the event logs related to outlook password prompt.. Do I need to configure any perform or new captures to captures those events ?

Hi,
I'n my experience this can be cause by additional mailboxes mapped to the account.
On the client that is experience the password prompt, right click on the Outlook icon in the bottom right while holding shift. Then select Connection status. You should be able to see the connections to the exchange.
Check is there is any connection that is in the state connecting when you get the password prompt. The Type will tell you what kind of connection this is and if it's an additional mailbox or mapping.
When a user has full permissions to an mailbox it is automatically mapped to the user.
You can disable this if wanted.

Outlook password prompt after CU7 installation

Hi
I have Exchange 2013 in a resource forest. We use linked mailboxes.
The clients are connecting using Outlook Anywhere.
As Authentication we use NTLM.
This Weekend I installed CU7. This morning all users received a passwort prompt when starting outlook. After entering the password, Outlook can be closed and restarted again without a password prompt. But after a reboot of the client, the password prompt
comes again.
Any Suggestion?
Regards
Peter

Hi Peter,
I have never seen CU7 removed WindowsIntegrated authentication from AutoDiscover VD before, maybe some other reasons cause this. Great information. Thanks for your generous sharing : )

Outlook password prompt for mailboxes on Exchange 2013 CU1

I migrated a few users from our Exchange 2007 SP3 Update 10 server to Exchange 2013 CU1. Now in Outlook they are getting a password prompt, and it won't accept their password. Our public folders are still on Exchange 2007 if that makes a difference.
I tried running
Test-OutlookConnectivity -GetDefaultsFromAutoDiscover:$true
but it says it doesn't recognize the parameter -GetDefaultsFromAutoDiscover:$true
Here's the values for Get-OutlookAnywhere:
ExternalHostname : legacy.domain.com
InternalHostname :
ExternalClientAuthenticationMethod : Ntlm
InternalClientAuthenticationMethod : Ntlm
IISAuthenticationMethods : {Ntlm}
ExternalHostname : mail.domain.com
InternalHostname : clippers.domain.local
ExternalClientAuthenticationMethod : Negotiate
InternalClientAuthenticationMethod : Negotiate
IISAuthenticationMethods : {Negotiate}

Hi GraffitiK
How is your test? Did the issue resolve?

Outlook Password prompt for Linked Mailboxes from certain Domain

Hello,
As part of a migration project, I'm trying to connect Outlook with Linked Mailboxes from users in a trusted domain.
I'm able to create the linked mailbox on the Exchange 2013 (CU7) server without any issue, but when I try to configure Outlook for these mailboxes, it is prompting for credentials permanently and won't start. Log on to OWA with the same user from the trusted
domain is working fine.
I'm able to configure Linked mailboxes from another trusted domain without any problems.
I've already recreated the trust between these two domains (validation tells everything is ok)
DNS is configured with conditional forwarders in both domains and name resolution looks ok to me (ping and nslookup)
When I look at the LinkedMasterAccount of the mailboxes from this domain, I can see that there is only the SID (S-1-5-21-4033829......). The other linked mailboxes (from the other domain where it's working) are showing the Account name (domain\user)
Internal and External ClientAuthenticationMethod of OutlookAnywhere is set to NTLM
Infos:
DomainA: Domainlevel 2012 - Exchange 2013 - Forest trust to Domain B and C
DomainB: Domainlevel 2008 - Exchange 2010 - Forest trust to Domain A - Outlook for linked Mailboxes of DomainA works fine
DomainC: Domainlevel 2008 - Forest trust to Domain A --> can't connect Outlook to LinkedMailboxes of this domain.
Is there anything else I can check?

Hi,
Please check whether the server is configured to only accept NTLM version 2 and reject NTLM and LM, and the Outlook client computer is not configured with the same LAN Mananger authentication level.
Check DC, Start -> Programs -> Administrative Tools -> Security Options -> Note the LAN Manager authentication level.
Check DC's policies, Start -> Programs -> Administrative Tools -> expand Security Settings\Local Policies -> Security Options -> Note the Lan Manager authentication level.
IMPORTANT： You may also have to check policies that are linked at the site/domain/organizational unit levels to determine where the LAN Manager authentication level must be configured. Configure the LAN Manager authentication level to "Send
NTLMv2 response only". If you want to implement NTLM version 2 in your network, make sure that all computers in the domain are set to use this authentication level.

Why does Outlook keep prompting for password

We have seen our community members ask questions about Outlook keeps prompting for credentials many times. This issue could be caused by numerous reasons. Below is a list of the most common reasons for this problem:
Outlook is configured to prompt you for credentials
Incorrect password cached in credential storage
Required Authentication Settings for outgoing server and incoming server
Outlook Anywhere is not configured to use NTLM Authentication
Corrupt Outlook profile
Slow or unstable network connection
Antivirus programs
Shared calendars
Outlook is configured to prompt you for credentials
If you are using an Exchange account, there is a setting in your Outlook profile to always prompt for logon credentials. To find the setting, please follow:
1. In Outlook 213, go to File tab > Info >
Account Settings > Account Settings…
2. Highlight your Exchange account and click Change button.
3. Click on More Settings button.
4. Select the Security tab.
5. Under the User Identification, make sure the “Always prompt for logon credentials” option is not selected.
If you are using other types of email, please make sure you have ticked the option “Remember password”.
Incorrect credential cached in Credential Manager
Your Windows system stores user credentials on your computer. If the cached credentials are incorrect, you will be prompted for password. This issue usually happens after the password for your domain user account is changed. Before your password changed,
you saved your credentials. The stored credentials are not overwritten when Outlook triggers the authentication prompt even if you enable the Remember my credentials option.
To fix this issue, you need to remove the corrupted credentials, follow these steps:
Click Start, click Control Panel, and then click Credential Manager.
Note If View by is set to Category, click User Accounts first, and then click Credential Manager.
Locate the set of credentials that has Outlook in the name.
Click the name to expand the set of credentials, and then click Remove from Vault.
Repeat step 3 for any additional sets of credentials that have the word Outlook in the name.
Required Authentication Settings for outgoing server and incoming server
Different email provider may need different authentication settings. Please make sure you have set the server settings correctly. You can contact your email provider to gather the information.
In general, we select the “My outgoing server (SMTP) requires authentication” option and the first bullet “Use same settings as my incoming mail server”.
In addition, click on the Advanced tab and check if you have enter the correct Server Port Number and select the correct encrypt type. Below is a screenshot for an IMAP account:
Outlook Anywhere is not configured to use NTLM Authentication
The Outlook Anywhere feature allows you to access your Exchange account remotely from the Internet when you are working outside your organization's firewall.
When using Outlook Anywhere to connect to your Exchange server, we need to choose
the authentication method among Basic Authentication, NTLM Authentication and Negotiate Authentication. The difference among them is the way that the passwords are sent when connecting to the server. With Basic Authentication,
the password is sent in clear text. Using NTLM Authenticationcan significantly reduce the number of password prompts.
To check the authentication setting, please go to File > Account Settings > Account Settings,
select the Exchange account, and then click
Change. In the Change Account wizard, click
More Settings, and then click the Connection tab. Click the Exchange Proxy Settings button and now, you can see the settings under
Proxy authentication settings. Try to change the authentication to
NTLM Authentication and then check the issue again.
Slow or unstable network connection
If your network connection is slow or unstable, Outlook may lose connection to the mail server. When Outlook try to reconnect, it will prompt for the credentials. To verify this, please switch to a stable network environment and then check if this issue
persists.
Corrupt Outlook Profile
Corrupt profile may cause Outlook to no longer remember your password. Please try to create a new mail profile in Control Panel and reconfigure your email account in the new profile to fix the issue. To create a new mail profile, you can refer:
http://support.microsoft.com/kb/829918
Antivirus software
Antivirus software usually integrates into your Outlook and it may cause some conflicts. Try to temporarily turn off your antivirus software to check if the issue will be gone.
Shared Calendar
Shared calendars can impact the user credentials, this issue may also occur if you have shared calendars opened in Outlook. You can try to unselect the shared calendar to check the result. It’s recommended to not open the shared calendar unless you want
to view them.
If you have any comments, welcome to post in the forum. Thank you.

Nope...
I went through point by point by point, top to bottom, checking and verifying every single item as a possible cause for why my system (Outlook 2013 running on Windows 8.1 and connecting to Exchange 2010) insists on prompting me for my password every single
time I start Outlook. None of the solutions worked, my system still prompts me. I don't even have to supply a password. When the prompt dialog appears, I just cancel it. Within a few seconds, the bottom Outlook status bar changes to
"Need Password" with a key icon to the left. Then I just click on that message and immediately Outlook connects to Exchange.
The freaking software is BROKEN! Period.

Micrsoft Outlook somtimes prompting for username and password

hello All ,
I Have Exchange 2010 sp3 installed two mailbox servers & two HUB & CAS Servers and Outlook sometimes prompting for username and password .
how can fix it .
Thank you

Hi,
Please check the following points:
1. Does the issue happen to your external users or internal users?
2. For all users or some specific users?
If the issue happens to internal users, please configure the authentication in Outlook Security tab with Negotiate Authentication to have a try.

The goal - Eliminate issue with password prompts for Windows XP.
Any chance resolving this? CU install? Anything else?
Thanks.

Hi,
Based on my experience, the credential issue is mostly likely caused by authentication method.
And I recommend the following troubleshooting:
1. Change LmCompatibilityLevel on the windows XP client to a value of 2 or 3:
a. Click Start, click Run, type regedit in the Open box, and then press ENTER.
b. Locate and then click the following registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\
c. In the pane on the right side, double-click lmcompatibilitylevel.
d. In the Value data box, type a value of 2 or 3 that is appropriate for your environment, and then click OK.
e. Exit Registry Editor.
f. Restart your computer
2. Reset the windows credential store.
If you have any question, please feel free to let me know.

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 2003 - Continous password prompts in Outlook 2010

Hi.
A customer is experiencing continous password prompts in Outlook 2010. Outlook is configured against the Exchange 2003 BE server (FQDN) and Outlook Anywhere is configured to sync.customer.com with a valid 3rd party certificate.
Outlook is configured with Negotitate as Logon network security, setting this to basic/NTLM does not help. Connect to Microsoft Exchange using HTTP is set and configured with sync.customer.com, and msstd:sync.customer.com. All points checked except "On
fast networks, connect using HTTP first, then connect using TCP/IP", authentication is set to Basic. Changing authentication from Basic to NTLM seem to make the problem vanish.
Outlook Anywhere is functioning correctly and only prompting once for password when connecting from an external network. ISA is not configured for NTLM/Kerberos.
Exchange 2003 is located in main site in a resource domain. The prompts occur more often in two remote sites than the main site.
When opening Outlook RPCDiag shows established connection to BE and Active Directory, sometimes with prompt and sometimes without. After about 5 minutes the prompt may reappear, entering password does not remove the prompt, clicking cancel puts Outlook in
the "Need password" state, clicking this usually successfully connect Outlook to Exchange. Other times this just cause the prompt to reappear.
I´ve tried adding the internal and/or external IP address of the ISA server as sync.customer.com in the host-file on a client and forcing RPC/HTTPS through the DisableRpcTcpFallback, still getting the password prompts.
We have also been through the KB975363, changing the MaxConcurrentAPI on all domain controllers.
Finally, we know Exchange 2003 is in a unsupported state so there is no need to comment this.

Hi,
Firstly, I'd like to explian, basic authentication requires the user to enter domain, user name, and password. Thus, it's an expected behavior that the credential prompts once when the authentication is set to basic and it disappears when it's NTLM authentication:
http://technet.microsoft.com/en-us/library/aa996225(v=exchg.65).aspx
For the issue that the credential keeps prompting, I'd like to confirm if Outlook 2003 works well. If yes, you can refer to the following article:
http://support.microsoft.com/kb/927612/en-us
If all outlook clients prompt credential, you can check the RPC over HTTP connectivity by ExRCA:

Outlook keeps prompting for password

This is a weird situation. User logs in to domain without issues and is able to access outlook. However, during the middle of the day, outlook keeps prompting user for authentication or password.
Profile has been re-created. ESSO cache was cleared, but still the same thing. Created separate email profile for other email accounts she access, but same issue still occurs.
Has anyone seen this issue and what resolution have you used.

Truly I don't mean to disparage your comment/proposed answer, but in today's day and age one should really never, ever use "Remember my Password" for any context. This means web forms even on trusted sites and/or when the windows subsystem
is called to prompt you for your Windows Password.
This is a very bad practice for two reasons:
The first is due to Heartbleed and/or the like-wise thousands of malware that are constantly attempting to hijack your username/password entry. Please understand that when you ask systems to remember your password what is happening on the backend.
That password is being saved somewhere, or a cookie is being set. The only "safe" way to remember your password is in your head.
The second is due to account lockouts. If you routinely use "Remember my Password", especially across several computers (home, work) and devices (ActiveSync on iPhone/iPad, etc.) then you are a prime candidate for getting a locked out domain account.
We, in IT, won't like you very much after that :) Please understand that when you choose that option, those features do not remember to update all those places you have saved when you reset your password (every 90, 120 days, whatever your organization's
password policy dictates). As soon as you do, you will begin to lock out all sorts of applications and/or your domain account.
As I said above, the only "safe" place for you to store your password is in your brain. Now this gets difficult over time because you also don't want to use the same password over and over again for different places. Because when you
do get compromised (and I do mean when, not "if") that hacker will not only have your password, but also will know where all you have used it. And the first place they will go is your online Bank, Savings, online stock, etc... If
you don't routinely rotate your passwords, and use different ones then you may just as well hand over the keys to your house.
Use a format like "for every letter O, I will use a zero", "I will use a 3 for the letter E" or "instead of the letter S, I will use a 5", then pick something only you would remember, like "that trip to Puerto Rico
was memorable"... so your new password would be Pu3rt0 5ic0. Throwing in a space helps combat robot hacking. Now this is slightly bad too though because they are dictionary or common words. Then keep on that theme and think up a few
more passwords that you will remember, AirPlan3 Tix, 5andy B3ach3s! <-- and if/when they require special chars, throw a "bang" or "exclamation mark" on there.
If this seems a huge imposition (my gut would tell you to get over it, but in IT, hey we try to help too!) ask your Systems Admins/Architects to implement a Federation provider (like OKTA or OneLogin, or ADFS - probably least preferable). Then they
can setup the multitude of hosted service providers (think "cloud applications" though I hate that word) for either SAML based Single Sign On, or leverage that service's proprietary "Password Safe" aka "Secure Web Authentication".
Or lastly, for yourself you can go download KeePass. This is a "wallet" style application that you can lock away all your passwords; though you will need to remember to update them in KeePass as you then may reset them. Single Sign On
is always more preferential because they will typically use your Domain credentials (i.e., Kerberos authentication local to your Org's domain) as part of the solution.

Mavericks Outlook 2011 Password Prompt (Solution)

I have a Macbook Pro running Mavericks. Outlook 2011 kept pushing the password prompt to the screen. I have searched and searched for a solution. I have seen the following solutions offered:
Issues with Keychain corruption
Outlook autodiscovery
Deleting files
Reinstalling Outlook
Reinstalling Mavericks
I'm not doing any reinstalls because until I installed Mavericks I didn't have Outlook problems. So reinstalling Outlook and the OS was not an option for me because I do so much work on my Mac.
But I'm in IT so I decided to begin to dig deep into this because regardless of the proposed solutions offered there was still someone in the thread say, "I tried this but it didn't work for me." I too was one of them.
The distinction I needed popped into to my face looking at another thread but the user didn't answer the guys question. He simply asked the complaining user, "Are you on wireless, 802.1x?" That was it.
I was on wireless 802.1x environment.
Our wireless controller does authenticate to the Active Directory server.
I did use the iPhone Configuration Utility to create my wifi profile.
I did import the CAs needed for my profile.
My profile does work.
But what about the Exchange portion of my profile?
The Exchange portion of my profile was EMPTY? The password kept coming back because my user/machine level authentication was being managed by my wireless profile. Due to this my profile took responsibility for authenticating to my WIFI connection as well as my Exchange account. In the end the profile seems to takes precedence in the 802.1x authentication.
I went back the iPhone Configuration Utility, clicked on my profile, clicked on the Exchange and filled in my domain\username, my email address, my password and a few other boxes. I exported my profile to my desktop and clicked on it. Since my profile still had the same name I was asked if I wanted to "Overwrite" my existing profile to which I responded, "Yes"
Since yesterday I have not had anymore issues with Outlook or Office Communicator.
To add I still disabled App Nap.
I hope this helps anyone. If you have migrated from MLion to Mavericks running MS Office you will have this problem if you are working in an 802.1x wireless environment.

I've included a pic of the iPhone Configuration Utility showing the Exchange section. I hope this helps someone.

Audit failures on Exchange 2010 and password prompts in outlook

Starting last Thursday after I patched my domain controllers and other Windows systems and rebooted my Outlook users are being prompted for username/password continuously and my Exchange security logs reflect audit failures for NTLM which I think is triggering
the prompt. The same users also have an audit success via Kerberos.
If the password prompt it cancelled Outlook can send and receive email just fine but the box continues to pop up occasionally.
I've worked on this for several days now and can't figure it out. The audit logs on the DC's are clean with no audit failures.
The issue is also affecting Visual Studio users who log into a Team Foundation Server, they are continually prompted for credentials and can't get in and the audit logs show the same thing.
I don't think this is an Exchange specific issue but more of a broader authentication problem.
Can anyone shed any light on this?

We can remove this patch from all the DCs manually and check whether the issue persists.

Constant Password Prompting in Outlook

Hello,
I use outlook for my work email with a POP3 account through hosting.com. When I have my iPhone set to check my work account as well, and I have outlook open- I frequently (every few minutes) get an "Enter Network Password" prompt on outlook. Is there anyway to fix this? It's really annoying. I have resulted to forwarding my work email to a Yahoo! account that my iPhone is attached to- though this is a pain as I don't want to reply to my clients from a Yahoo! domain- I need to reply to them from my company's domain.
suggestions?
John

I have set Outlook to only check for email once every 15 minutes. Before it was set to check every 3. My iPhone is now also set to check once every 15 minutes. The problem no longer arises. I think it might be that the mail server was getting to many log-in queries. regardless, changing this option has eliminated the problem (at least for the last 3 hours).
cheers!

Exchange 2013 - External Windows XP/Outlook 2007 Password Prompt

I have an Exchange 2013 server and everything is working correctly internal with XP clients that are connected to the domain. My problem is that the Windows XP computers that are connecting from outside of the office that aren't connected to the domain
and have local usernames and passwords keep getting the password prompts. I put in the correct domain\username and password and it connects. The if I close and reopen it asks me for the password, I have saved the credentials but it still asks.
I have look and applied these settings from these articles but I'm still having the issue. All of the internal and external names match my GoDaddy SSL certificate (mail.domain.com). Get-OutlookAnywhere shows:
ExternalHostname : mail.domain.com
InternalHostname : mail.domain.com
ExternalClientAuthenticationMethod : Negotiate
InternalClientAuthenticationMethod : Ntlm
IISAuthenticationMethods : {Basic, Ntlm, Negotiate}

Internally installed Outlook 2010 prompts for password using external smtp email as user id

Hi,
After exchange 2007 to exchange 2013 migration all internally connected outlooks 2010 (xp, vista, win7, win8) prompt for password using external email user address as user id.
Below some of my settings and informations.
Internal domain: contoso.local
External domain: contoso.com
Exchange is NOT published to Internet at all.
Internally OWA, ECP runs OK.
Test-OutlookWebservices with user.name(at)contoso.local or contoso\user.name - runs OK
Test-OutlookWebservices with user.name(at)contoso.com - fails
Common scenario - (all happens internally):
1.User starts Outlook
2.Outlook prompts for password with default user.name(at)contoso.com as id
- while user tries to authenticate using his domain password - outlook re-prompts
- while user changes id from user.name(at)contoso.com to user.name(at)contoso.local or contoso\user.name and authenticates - Outlook connets to exchange and till next Outlook it runs ok.
I am bus with that issue since 1 week and I am already bit tired. I was looking for answer via gogle/bing and went through tons of "Outlook perpetually prompts for password" threads and blogs. No success.
Do you have any clue where else start to play with that?

Hi,
Thank you for answer - no luck
>NExt og to Connection tab - Exchange Proxy settings - Proxy authentication settings - is it set
>to NTLM or Basic?Give it a try on one of them.(if set to NTLM change to basic and vise versa).
On both settings the same results - Outlook is prompting for password.
>Another thing you could try is og to Internet Explorer - tool -internet options- Security - click local
>intranet - >custom Level and scroll Down to bottom and put check mark on automaticly logon
>With current username >and password.
>Do this on Trusted sites as well,if Your domain is listed under trusted sites
The same results - Outlook isprompting for password.
Should not be some kind of mapping set somehow in AD between user.name(at)contoso.com and user.name(at)contoso.local?
I have impresion that issue is somewhere in the fact that outlook is trying to connect using contoso.com instead of contoso.local in ntlm credentials.
