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 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:

Hi,
First, you can try to clear the credential cache in Credential Manager to check if it helps. See:

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?
An account failed to log on.

Hi,
It is a known issue if you install the following security updates on March 10, 2015:
http://support.microsoft.com/en-us/kb/3002657
The user would be prompted with credentials when NTLM is used to authenticate these Active Directory domain users and services.
We can remove this patch from all the DCs manually and check whether the issue persists.

Password prompts - Exchange 2013 RTM vs. [Outlook 2007 & Outlook 2010] - Fully patched

Exchange 2013 RTM - Multi-Tenant
ExternalClientAuthenticationMethod : Ntlm
InternalClientAuthenticationMethod : Ntlm
IISAuthenticationMethods : {Basic, Ntlm, Negotiate}
Clients using Outlook Anywhere only, not Exchange domain members.
1. Windows XP SP3 (fully patched), Outlook 2007 SP3 + Nov 2012 Patch - When launching Outlook prompts for password only once.
2. Windows 7 (fully patched), Outlook 2010 (fully patched) - When launching Outlook doesn't prompt for password.
I'm aware of this:
http://support.microsoft.com/kb/956531
The goal - Eliminate issue with password prompts for Windows XP.
Any chance resolving this? CU install? Anything else?
Thanks.
Memento Mori

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.
Thanks,

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 : )

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.

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}

Outlook Anywhere Password Prompts - Only on certain external networks

I am running a standalone Exchange 2007 SP3 server on Windows Server 2008. I have published Outlook Anywhere via ISA 2006. Outlook Anywhere is configured for Basic Authentication. All clients are using Windows 7 with Outlook 2007 with latest
service pack. This is not a new configuration, I have been running this for quite some time.
I have a strange issue going on. The issue is that Outlook Anywhere users receive a prompt for their username and password ONLY when they are connected to certain external networks. Users began reporting this several months back. It happens on
all mobile users that I have tested with.
Basically, what happens is a user takes their domain joined laptop out to another work site. This site is not connected to our network. The IT department of the site connects my users laptop to there network. User then starts Outlook, Outlook
connects via HTTPS as it should, down in the bottom of Outlook it shows that it is connected to Exchange. However, within usually about 30 seconds the password prompt comes up. User puts password in and clicks remember and OK, but
the password box comes right back up. Sometimes it will except the password and run for a little while but then prompt again.
If I check Outlook Connection Status it displays that connections are established via HTTPS as they should be. Latency isn't too high averaging about 150 - 300ms.
If the user clicks Cancel instead of entering their password, Outlook will continue to run and it can send and receive email. Connection status still will show connected. However, if the user opens the address book and tries to access one of our
Address lists other than the GAL, then Outlook displays a message stating the user doesn't have permission. If the user clicks need password at the bottom and then enters their password at the prompt the address book will work.
This happens at several work sites, each different networks. My first thought is some sort of firewall issue at the sites but the IT at the sites say there should be no firewall blocking going on.
I have tested probably 5-6 other wifi networks, both public and private and Outlook Anywhere works perfectly on everything but these few work sites.
I have used testexchangeconnectivity.com at the sites at it tests fine. I have cleared the cached credentials from "Manage Windows Credentials".
Any assistance is appreciated.

If the user clicks Cancel instead of entering their password, Outlook will continue to run and it can send and receive email. Connection status still will show connected. However, if the user opens the address book and tries to access one of our
Address lists other than the GAL, then Outlook displays a message stating the user doesn't have permission. If the user clicks need password at the bottom and then enters their password at the prompt the address book will work.
This happens at several work sites, each different networks. My first thought is some sort of firewall issue at the sites but the IT at the sites say there should be no firewall blocking going on.
I have tested probably 5-6 other wifi networks, both public and private and Outlook Anywhere works perfectly on everything but these few work sites.
I have used testexchangeconnectivity.com at the sites at it tests fine. I have cleared the cached credentials from "Manage Windows Credentials".
Any assistance is appreciated.

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}

Exchange 2013 external outlook autodisover password prompt

I've set up a new infrastructure for our network with a 2k12 DC and a 2k12 member running Exchange 2013. The internal domain is set up like ad.domainname.com and I've configured mailflow for domain.com on Exchange which works perfectly. Internal autodiscover
works like a charm and with https://testconnectivity.microsoft.com/ I get green results for the autodiscover.domain.com on activesync, autosetup and outlook connectivity. I've used a comodo wildcard ssl
certificate for the domain.
However when I try to use autosetup on outlook it gives a password prompt on both the 2nd and 3rd step which I have to enter like domainname\username to get past them. After that it works fine but I want it to configure automatically without the extra password
prompt.
On mobile devices it searches for the settings and then asks for the servername and domain credentials. I would like this to be auto configured as well but I can't find the reason why it prompts for this.

For the Outlook setup are you using a Domain joined computer or a nondomain joined computer? For NonDomain joined computer you will always get prompted for a password because there is no AD Security token to send to Exchange to verify. Same thing
with ActiveSync. Your phone isn't joined to the domain, so it has to ask for a password to verify your identity.

Outlook 2010 users getting Password Prompt until shared mailboxes are removed

Hi,
some (around 20) of my 3000 outlook 2010 users are getting Password Promts while using outlook.
This started end of last week without any change to the environment.
The prompt goes away if we unmount and remount additional mailboxes they have mounted.
Any idea what could be causing this or where to start debugging?
Backend is Exchange 2013 and 2007 in migration.
Thanks for every idea

Hi,
How did you mount additional mailboxes? Via File > Account Settings > Account Settings > Double-click the Exchange account > More Settings > Advanced tab > Add?
Are the additional mailboxes hosted on the same version of Exchange server with thoese mailboxes with the password prompting issue? If this is the case, this issue often happens if you have a hybrid deployment of Exchange Server. To resolve the issue,
please have a look at the following KB article and follow the instructions to fix it:
https://support.microsoft.com/kb/2834139?wa=wsignin1.0
Please let me know the result.

Outlook Anywhere, NTLM, TMG, password prompt but cancels works?

I've managed to get NTLM authentication working with TMG and Exchange 2010 (Make sure you switch your Application Pool for the RPC app over to a local system!). We also run Lync.
So here is the thing. I log into a domain laptop with cached credentials and then connect to a Verizon access point. Now Lync connects automatically no password needed. Then I open Outlook which connects no problem no password needed!
Awesome that is what I wanted. Then after about 30 seconds......password prompt. If I enter the password everything is good. If I click cancel the little need password icon is displayed down at the bottom of outlook. I click on that and outlook reconnects
without me ever having to enter a password.
I have been watching the log on the TMG server and I don't see anything odd going on other than and occasional Status 64 The specified network name is no longer available error which I understand from other posts is by design.
It's not a show stopper by any means but I just don't understand what is going on here. Anyone have any ideas?

Hello,
Firstly, please test Outlook Anywhere in an internal environment:
On a internal outlook client, check on “on fast networks, connect using http first, then connect using TCP/IP”.
If the issue does not work, the issue is related to the TMG, you may need to inquiry on the TMG forum for more accurate suggestions.
Thanks,

Outlook 2013 password prompts

When I'm using Outlook 2013 client from home laptop (not joined to domain)I get random password prompts saying connecting to [email protected] I just close them all (9 prompts) and I can continue to use Outlook normally. Outlook doesn't accept
any credentials to those prompts. Our Exchange server is 2010. How can I trace what is causing those prompts?

Hi
Check your credential manager for any old passwords. Is this an exchange or pop account? Try changing your authentication method in outlook to use basic instead of NTLM and see if the popups disappear.
