Outlook prompts for password

Hi
We are in a migration of Exchange 2007 to Exchange 2013, so for the moment it is a coexistence.
I migrated 2 mailboxes to Exchange 2013. After the migration, outlook started prompting for a password by starting outlook. Once the password has been entered, outlook works fine. But that happens only if outlook cache mode is active. If I disable cached
mode, outlook starts without prompting for a password.
So I deactivated cached mode, deleted the ost file and again activated cached mode. Now Outlook starts without prompting for a password, even if cached mode is active.
Deleting the ost file for 1 or 2 users is fine, but not if there are 200 more mailboxes to migrate.
I cannot reproduce the behavior with test mailboxes, created after Exchange 2013 has been installed into the organization. All these mailboxes can be migrated without password prompts.
By the way, I found different posts about the authentication settings for outlook anywhere. I found on Exchange 2007 that the ClientAuthenticationmode was Basic, while NTLM on Exchange 2013. So I changed it to NTLM as well. Everything is still working.
I am going to migrate 2 more mailboxes, and I will see tomorrow if the problem still exists.
Any Suggestion?
Regards
Peter

Hi Peter,
I also found many similar issues had been solved by setting to NTLM for Servers. Outlook will pass the authentication via Windows. It is the solution.

Office 365 Outlook prompts for password whenever outlook is restarted.

Hello Folks,
We have recently deployed Office 365 (We had Kerio email system previously, But we did not do a migration).
The problem is
Office 365 Outlook prompts for password whenever outlook is restarted
Tried the following workarounds,
1) Logon network security under More
Settings on the Microsoft Exchange Security tab
is set to a value other than Anonymous Authentication
2) Tried removing the Generic Credentials from Credential manager.
The is issue is only for some users (Majority).
(OS Platform: Windows 7/Windows 8).
Thanks in Advance

The first thing I would recommend to do is to make sure that your install missing Outlook updates and try again.
I would also recommend asking them in this forum: https://social.technet.microsoft.com/Forums/en-US/home?forum=outlook

Outlook prompting for password

User is promting for password in Enviroment Outlook 2010, Ex2013 , Windows7 .
User is accessing outlook through internet and VPN
to work around I have putted google DNS "8.8.8.8"on NIC card
Now user is able to access his outlook without any issue .
But I am sure when user will back to office he will face issue again as he his DNS will point to Google.
Publicly Autodiscover is publish on "RADIUS.HCL.com" as example
Localy "Outlook.HCL.com"
Here is my troubleshooting
So when I do nslookup to RADIUS.HCL.COM
it give wrong response radius.HCL.com.ad.hcl.com
Could you please help on this, I heard somebody its known issue with windows 7 . Any body have idea plz help

Hi,
Before going further, I would like to ask for some information:
Does this issue just occur on one user? If no, please switch to another PC to have a test.
Does Outlook work fine after closing the pop windows?
For troubleshooting, I recommend you to change method of authentication to Negotiate Authentication to have a try:
Open Control Panel, then choose Mail.
Click Email Account and then choose the account.
Click Change and then Click More Settings.
Choose Security tap and change the Logon network security to
Negotiate Authentication.
Unchecked the box that states Always prompt for login credentials.
Here is a thread for reference:

If this issue persists, please let me know.

Outlook prompting for password after password change

I have a client who has Exchange 2013 and the PCs run Windows 8.1 with Office 2013.
The users just started having the following problem. Their domain passwords are expiring and when they update them with a new one, Outlook starts prompting them for a password when they open it and periodically while Outlook is running. They keep entering
the new password and checking the box to remember it, but the password prompt keeps coming back.
I've checked and the account in Outlook does not have the box checked to always prompt for logon credentials. I did notice that the proxy authentication is set for NTLM so I changed it to Basic, restarted Outlook and there was no password prompt and the
user has not seen one since.
Any idea why having the proxy authentication set to NTLM would cause this after the domain password changed? It has been set to NTLM rather than Basic for years now. Exchange 2013 has been in use there for about 6 months and Office 2013 longer than
that. Windows 8.1 has been on the computers for 3-5 months so I don't think that's it either. I've tried with our domain account we have setup there and with a test user account by changing the password on them but with the proxy authentication set to NTLM
I haven't had the password prompt appear other than once the next time Outlook is opened after the password change, and that is to be expected.
So it's not every user account but a good number of them this is happening with.

I have an update.
There must be a GPO or setting in Outlook changing the proxy authentication to NTLM because this morning it was changed back to NTLM from Basic. They all either shut down or restarted their computers since I worked on them Friday.
One user got the password prompt one time when starting Outlook. She entered the password and that was it. But she was unable to connect to a shared calendar. She put her computer to sleep, woke it up, logged in, and then was able to connect to the shared
calendar. I don't understand that.
Another user could not get the password prompt to go away this morning no matter how often he input his password, and he also was unable to connect to the shared calendar. So I changed the proxy authentication back to Basic again, restarted Outlook (which
is required), got no password prompt, and he was able to connect to the calendar.
I realize the calendar issue is tied to the password issue. What I don't understand is why these people are getting the password prompt ever since they changed their domain password.
I have a test account and test PC set up in a VM and it does not have any of these problems. I've changed its password 3 times but I never get a prompt when opening Outlook and it is set to NTLM.
I hope someone out there has an idea why changing their password now is causing this authentication problem in Outlook.

Outlook prompting for password with new Exchange 2013

I have Exchange 2007 and 2013. I want to migrate to 2013 but I'm having issues in the testing phase. I have a test account that I moved the mailbox to the new server. I have a test PC with a modified hosts file that points to the new Exch
2013 server IP address.
When I log in with this test user, Outlook appears to connect and download the mailbox. However a Windows Security dialog box pops up saying Microsoft Outlook Connecting to [email protected] and it has a username and password field. No matter what
is entered here, it is NOT accepted, nor if forcefully entering the wrong information is the account locked out.
I can click cancel here and it proceeds to update the inbox and then says All folders are up to date. But at the bottom in Outlook 2013 it says Need password and Outlook's icon in the taskbar has a yellow triangle on it. I can send myself a test
email and I get it (I personally am on the 2007 server), but after it sends Outlook 2013 prompts again for the password, and since it does not accept anything, I have to click cancel.
I have done ALL the windows updates available on this test PC. Exchange 2013 is on CU6 which is the latest at the time of this writing.
Another thing is in the Lync 2013 client it says "Exchange needs your credentials". No matter what is entered here, it will not make this message go away unless you click the X on this warning bar. Lync itself appears to work regardless.
Any ideas?
I just changed the ExternalClientAuthenticationMethod from Ntlm to Negotiage. Now the Outlook prompt does accept the domain password, but I don't want anyone to have to enter any type of credentials just to get on. Note, this test is on the same
LAN as the servers, so I haven't even tackled an external test yet, though last time I tried it was the same results.

Ok besides LYNC 2013 asking for exchange credentials, I cannot get Outlook to work externally.
Externally to the NEW Exch2013 server, we are trying something different this time around. Instead of poking port 443 straight to the Exchange server from the outside world, we are trying what we did with LYNC. We are poking port 443 to an IIS
AAR reverse proxy to it's DMZ interface. It has another nic on DMZ 2 which allows port 443 to the Exchange 2013 server.
So I can use this with no problem for OWA if using an account on the new 2013 Exchange server. But if using an account on the old Exchange server, after I click sign in I get "The webpage at https://legacy.domain.com/owa/auth/owaauth.dll might
be temporarily down or it may have moved permanently to a new web address. ERR_RESPONSE_HEADERS_TRUNCATED.
Then of course Outlook Anywhere does not work. After I put in my password it sits there trying to connect with nothing.
Here is part of the IIS log on the AAR server.

My Outlook prompts for password every time it comes back from sleep or started

I've Microsot Outlook for MAC 2011, version 14.4.1 installed on my MAC Book Pro Retina Display with OS X Version 10.9.2 and everytime my outlook comes back from sleep or is started or there is a little fluctuation in Wifi signals, prompts me for my email password. I checked the option of save my passord, deleted all previous passwords from Keychain but it doesn't works, so please help. My email at my official domain (not free domains) address is configured perfectly and my send and received is working fine.

I have that problem in Outlook, too. When I get the Yes/No dialog box, I simply click "No" and my machine continues to receive mail.
It's most certainly a pain, but coming out of sleep, your network doesn't kick in for a minute or two. I don't think that it's really a bug in either OS X or Outlook: it just takes that minute or so for the network to wake up.

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.

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.

Outlook 2010 prompting for password

Hi everybody. I ran into an issue yesterday morning where at one of our sites Outlook 2010 has started prompting for a username and password. If the user types in their username as "MYDOMAIN\myuser" and their password, it lets them in but the Exchange
status shows as "Disconnected". If the user sets their username to just "myuser" without the domain on the front it lets them in and works as expected until they close Outlook, at which point they have to enter their credentials again.
The strangest thing about this is that it's only affecting one of our sites and only Outlook 2010. Users running 2007 and 2003 do not have the problem and only users at this physical location have the problem. Does anybody know where I can look? I have tried
clearing stored credentials, created new Outlook profiles and reset passwords. None of these things seem to have had any effect.

After changing a ton of outlook settings, deleting the user's account profile on outlook, deleting their domain profile from the effected computer, trying to fix the registry, deleting stored credentials, etc.... almost everything else I found something
that FINALLY worked for me after over a year and about 12 different users being effected.
in the past I would just give up after much frustration and upgrade them to Office 2013 but that gets very expensive especially when I have 57 other users that could potentially run into the same issue.
Here is what I did.
- back up the user's data. log out and log into local admin
- delete the user from the local registry
- repair Office 2010 through control panel/programs, restart
- have user log back in with their credentials to make new local profile. recover their backed up documents. log out and log back in as local admin.
- install hotfix KB2597011
- restart computer
- install hotfix KB2583935
-restart computer
- log in, open outlook and setup user's account.
Some of these steps may be skipped as I didn't find the hot-fixes until after I repaired office, however I am just providing what I did in the process to end up with a working outlook again.
Some things unique to my situation that may or may not help.
- I noticed some of the computers have Office2010 32bit installed on 64 bit machines.
- Some of the users were swapped over using a profile mover program when we moved to a domain environment.
- For me this always happens when the user's passwords expire and they have to log in to the portal to change it. Then outlook starts with the repeated prompt for passwords. It is always computer specific and nothing but what I provided above has worked
other than re installing windows 7 and then office or upgrading to office 2013.

Outlook 2010 keeps prompting for password

Hi,
We use Exchange 2008 and Outlook 2010. For some reason, Outlook 2010 keeps prompting for password. My use entered the password and checked "Remember Password" box, but next morning when he logged in, he still got the prompt.
I removed the Outlook credential for Outlook listed under Password Credential in Control Panel, but still no help.
Please advise!
Thanks in advance!
Grace

Hi Grace
1. Open Outlook 2010. Click File>Account Settings>Account Settings.
2. Click the E-mail tab, click the Exchange Online mailbox, click Change…
3. Click More Settings…. Click the Security tab, make sure the Always prompt for logon credentials box is unchecked.

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.

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.

I cannot download an app from the app store, it keeps loading until it says "You have already purchased this app so it will be downloaded no at no additional charge", and then it prompt for password and I input it after which nothing happens.

I cannot download an app from the app store, it keeps loading until it says "You have already purchased this app so it will be downloaded no at no additional charge", and then it prompt for password and I input it after which nothing happens.
I know my icloud has record of my installing this app before, but that was the first install that was failed during that time some other apps also keeps loading without respond whey they updated itself, and this app didn't install before I restart the device. But I don't see this app on my device after I restarted the device so it should have been installed on my device. It seems icloud has created some kind of dead loop that makes it not able to get the correct status about this app on my device.
I have no problem install this app on my other device (iPad) with the same account, but just fail on my iPhone. And it just fine installing other apps...... What happened !!?? @@
Please help !!!

Someone help! I dont know how to do this and please put the words into an easy way to understand because im young...

XFA Pdf form call secure webservice without prompt for password

Hi,
We are using XFA forms within the company. We have created many (400+) interactive forms with fields to fill manually.
Now the business would like to lookup account details. They want user to be able to enter account number and then lookup details through webservice.
The webservice is created on HOST/CICS and in COBOL. We need security on HTTPS and we cannot accept that the user is prompted for password.
Our security department state that normal practice is to use KERBEROS token that gets authenticated later - is that possible with Adobe Reader??
Have anyone developed this functionality within XFA forms and Adobe Reader?
Thanks in advance,
Thomas Groenbaek

Reader can make Web Service calls but the form must be Reader Extended by LiveCycle Server to allow this. It does support secure web service calls but it does uid/pwsd or certificate authentication. Note that the web service can only return simple types. Objects cannot be returned.

Prompting for password and username only when using dynamic parameters

Post Author: Co3023
CA Forum: Crystal Reports
How do I stop CR XI prompting for password and username only when using dynamic parameters. When no dynamic parameters are used CR XI isn't prompting for the DB user name and password. The report is run from an application which passes the user name and password. I am using Oracle and the problem is both with the native oracle driver and the ODBC RDO driver.

Post Author: jehanzeb
CA Forum: Crystal Reports
I didnt ask you to change it to static I said I took the parameters totally out of the report. Saved it. Then re-enter the dynamic parameters into the report and it worked for me. That might have worked for you, not sure why you changed it to static.
Ok I have just created a quick report using dynamic parameters, it didnt ask me for the username password.
Can you create a sample report - just to test the db? and see if it works? add only 1 or 2 fields in the report, create parameters (dynamic) and see if it works
why don't you embed the username and password in your application, it won't ask for username password then.

Prompting for passwords even i configured ssh password less authentication

There are two servers :
1. Site
2. Testing
from site server i want to connect testing server with ssh password less authentication.
i generated public and private keys with ssh-keygen -t rsa on site server.
cat id_rsa >> authorized_keys
cat id_rsa.pub >> authorized_keys
i appended id_rsa.pub ( public key site server ) to authorized_keys ( testing server ) with below command .
ssh [email protected] "cat >> ~/.ssh/authorized_keys" < ~/.ssh/id_rsa.pub
am i missing some point in performing procedure for ssh password less authentication ?

I would expect you to add the RSA public key to the "authorized_keys2" file and not the "authorized_keys" file.
