How to prevent Outlook asking for credentials exchange every time?

Have you been asked for exchange credentials when opening Microsoft Outlook? If yes, you may notice the Windows Security dialog box pops up when Outlook launching every time. See screen shot below. Normally you can fix this problem with checking the Remember my credentials after entering your credentials, and click the OK button.

However, in some special cases, it asks for exchange credentials every time when launching Microsoft Outlook, but there is no option of Remember my credential at all in the popping up Windows Security dialog box. (See the following screen shot.) In this article, I will guide you to fix this problem and prevent Microsoft Outlook from asking for exchange credentials with configuring Account Settings quickly.

Step 1: Open the Account Settings dialog box:

  1. In Outlook 2007, please click the Tools > Account Settings;
  2. In Outlook 2010 and 2013, please click the File > Info > Account Settings > Account Settings.

Step 2: In the Account Settings dialog box,

  1. Go to the E-mail tab;
  2. Click to highlight the exchange account that asks for logon credentials every time when opening Microsoft Outlook;
  3. Click the Change button.

Step 3: In the new dialog box of Change Account, please click the More Settings button.

Step 4: In the popping up Microsoft Exchange dialog box,

  1. Go to the Security tab;
  2. Uncheck the option of Always prompt for logon credentials;
  3. Click the OK button.

Step 5: Now you get back to the Change Account dialog box, please click the Next button and Finish button successively.

Step 6: Click the Close button to exit the Account Settings dialog box.

After configuring the security settings of specified exchange account, it won’t pop up dialog box and asking for exchange credential when opening Microsoft Outlook any longer.

    For non-experienced user

    Close down outlook completely

    1
    Control Panel > (view by icons, not categories) > mail > Show Profiles > Add > (call it whatever you like) > change the dropdown to the new one you just created
    This will recreate the profile settings and you will need to re-add your mailboxes

    2
    C:\users\(you username)\appdata(this is hidden so make sure you can see hidden files - google guides available for this)local\microsoft\outlook
    eg
    C:\users\BEN\appdata\local\microsoft\outlook
    This file, rename it to "Outlookold"
    (this backs up the file so we can get it back by changing the name back to "Outlook" if need be - if the fix works, delete this to save yourself some space after you're done)



    3
    NOW, this is the first time you should be trying to open outlook - it will take a while but should load up after recreating the configuration folder and the configuring your account - then just re-add your mailbox(es).




    For experienced users
    *insert disclaimer about being careful with RegEdit*

    reg delete "\\%asset%\HKEY_USERS\%SID%\Software\Microsoft\Office\16.0\Outlook\Profiles\Outlook"



    For super users

    *insert disclaimer about being careful with RegEdit*
    HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\Profiles
    locate the mail profile that's active
    go to 9375CFF0413111d3b88a00104b2a6676
    Find which one has the affected mailbox in "Account Name"
    Note the "Service UID" - go to the binary value in the "Profile" key that we're in
    in here, find the REG_BINARY for "01023d0d" and make a note of the binary - go to the binary value in the "Profile" key that we're in
    Right Click > New > Binary Value

    Name = 00036619
    Value = 01 f0 00 80

    M$ is a sack of poo. I can't believe nobody has come up with a professional mail, calendar and contacts package to rival this sack of horse sh*t. The button was already unchecked so this did not help with a recurring problem.

    To me was necessary one step more:
    Change the option "logon network security" to "password authentication" instead "negotiate authentication" on Exchange settings window.

    The option to click on or off to always prompt for logon credentials is grayed out and I can't select it.

    so , I went in and my ' always prompt ' was also not ticked. I ticked it and it has fixed the problem.

    I worked through all of these steps above, but got to the last step and the box "Always prompt for logon credentials" was already unchecked. The problem is still there.

      I have the same problem.

      Did you ever get yours fixed. IF so what did you do?

        You need to go to Control Panel > Users > Manage Your Credentials (link on the left hand side of Windows 10 Explorer) > Windows Credentials > :

        Under Generic credentials, look for "MS.Outook.15:[YOUR ACCOUNT NAME]". If there are two entries for the same account, delete the one which ends in "PUT". This should fix your problem. The problem arises where two or more entries/keys exist and Outlook does not know which one to use, so it requests on start-up of the program.



        Before doing so however, I would advise you to back up your credentials.

          Thanks Stu, that worked perfectly for me... although I didn't have a "PUT" entry, just 2 entries for the same account.... deleted them both and at next Outlook restart entered the correct credentials, ticked the "remember" box and worked fine ever since. Problem occurred because my exchange account had been deleted and then re-created with same e-mail and new password.

            Allan, mine happened the same way! Although I was weary about deleting anything so I just updated the credentials to the new passwords and all is well in La La land!

    Outlook keeps prompting for password problem can be solved by changing logon network settings. From control panel, click on mail icon and select your profile. Click on More settings and change the logon network security to anonymous authentication. In this way you can solve Outlook Password Prompt problem.

      There is no "more settings" when I select a profile. There is only add, remove, properties and copy.

      Took me 15 minutes on the phone with Microsoft. control panel-email-add profile-add the same profile but call it something different-always use that as default. Works great!!

      Thanks Midon(sp) at Microsoft!

    Both of the solutions posted on this forum didn't work. I have deleted all credentials related to outlook, and verified that the pop credential box was unchecked. and it still continues to pop up. does anybody have any other solutions?

      Repairing Office365 seems to help. But the issue pops up again if the network connection fails or any other issue in the network.
      So, Repair should help you as long as your network connection is fine(not disconnecting intermittently).

      I did a repair of Office365, and it seems to fix it. But the problem pops up again when there are some issues with network connection.
      Repair, and as long as the network is fine, I guess there should not be any problem.

    I am having issues too. When the popup comes up, it wants me to sign in with a SPECIFIC email password (it already has the user name there)
    When I try to erase the username and put my current sign on info in, it won't accept it because it already wants the account info for my old email that
    I do not even use anymore! I am beyond frustrated. I have been in the control panel - actually tried deleting that account from the Windows user credentials
    and still not fixed. I have also done everything listed above.

    I have tried to do all the instructions listed in this forum to fix Outlook 2016 from asking for Windows Security login, and I can state a fact that they don't work.
    Firstly. in the options, the option for User Identification cannot be turned off, because it's already off, AND IT STILL ASKS. I've even tried turning it on, rebooting the PC and re logging in, then turning it off, but it's always the same, this Windows Security popup.
    Secondly, I can open my Outlook from a browser, with the same credentials Outlook 2016 is asking for, and ITS FINE
    Thirdly, Outlook 2016 will NOT remember my credentials even tho I tick the box marked 'Remember My Credentials' no matter how many times I tell it to.
    I've cleared the credentials numerous times via Control Panel, as also suggested, and to no avail. Even removed the account and re-created it, but IT STILL WONT WORK.
    If I can't get this fixed, then I'll be dumping Microsoft Office 2016 for good, and going back to Office 2003, never had this trouble with that. Strange how Thunderbird also has no problems accessing my Outlook account. Microsoft need to produce the right answer to this problem. But they all come up with this, and, as I said, it don't work.

      Bryan,

      I have been having exactly the same issue. Taken all suggested steps including Windows Credential Manager edits as well as group policy edits. The strange thing is that it is on my new computer (MS Surface Pro 4) that I am having the issue and not on my previous laptop both running Windows 10 and Office 2016. One thing that is different is that when I set up the Surface I chose the option saying that it would be associated with my company whereas on my other laptop I just set it as default and added the Outlook account separately. Wish we could get an answer for this. So frustrating.

    FIXED

    First, this documentation is worthless. I will tell you how to fix it.

    1) login window appears
    2) in the user area type in your actual user when you login
    3) type in your email password
    4) click remember credentials
    5) fixed

      You are the worthless for not reading the first lines. Everything is there. But you must read first. Then think and then write blabla...

    Scott · 3 years ago
    FIXED

    When the login appears don't use the default user. Get it to be blank. I can't recall how I got there, but I think it's just one click away. Type in your user name for your email and the password. That worked for me. It never comes up again. I believe the first time it didn't work, but then tried it again and it worked.

    For me, i will tell you what really worked:
    Go to control panel user settings and credentials, clear all credentials related with outlook.
    simple as that.

      Have you tried creating a new profile? If you are using an enterprise version of Windows or Office Suite and it is hooked into your AD account the profile may be corrupt and just needs to be scrubbed away and new one created
