Outlook 2013 / Exchange 2010 constantly prompting for password

I as well as many users keep getting prompted for User/pass in outlook. This usually happens when I go from LAN to WIFI or from office to home. For example, If I close my laptop (not shut down) and head home then log back in and connect to my
VPN I usually get prompted for my user/pass for outlook. I type the correct user/pass but it does not accept and immeadiatly prompts for me to re enter. If I close down Outlook and re open the issue is fixed however this is not fixing this issue
and the owner of the company is receiving this error as well. I would like to find a solution so that either it does not prompt and automatically updates once it is reconnected with the network via VPN.
Any suggestions?
Thank you
Outlook is simply not good at that with the existing protocols in Exchange 2010. Exchange 2013 uses MAPI over HTTP which may make that experience better.
Switching networks with Outlook open is typically not a good user experience.

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 2010 - new prompting for password

After installing Office 2010 Beta and working fine for about a month and a half, Outlook started prompting for a password. The machine is on the domain so the Outlook did not prompt before. If you cancel the prompt, everything seems to work fine. This happens on both Windows 7 64-bit and Windows XP. It started happening to all known users on Office 2010. The problem started on January 8, 2010.

I have searched all over for a solution to this crazy problem and some of them highly technical and poorly explained and were for outlook 2003 and 2007. Finally I found this less than 2 minute fix that works. http://www.howtogeek.com/howto/windows-vista/fix-for-outlook-2007-constantly-asking-for-password-on-vista/
This is not my fix but glad to pass along something that actually works. Give Kudos to the "how-to-Geek" and post in other forums to help out all your frustrated friends.
1. Close outlook!
2. go to my computer and then paste this into the address bar. %userprofile%\AppData\Roaming\Microsoft\Protect
3. rename the very long file name S-1-5......etc by appending "-old" to the end of the existing file.
4. now re-open outlook and you may be request for your password. If so enter it and check the remember password box
5. now go back to %userprofile%\AppData\Roaming\Microsoft\Protect by searching in windows explorer or my computer and you should see the renamed long named file
and a brand new long named file.
This should work for you. If not, then do a shut down and reboot a time or two. Then try reopening outlook 2010 and your problem should be fixed. Save
this link: http://www.howtogeek.com/howto/windows-vista/fix-for-outlook-2007-constantly-asking-for-password-on-vista/
because this problem is likely to recur sporadically because of microsofts pushed updates that cause more problems than they solve. Turn off automatic updates so MS cannot keep screwing up your system and snooping.
This fix was explicit for Vista but worked fine for me on Windows 7 64 bit running outlook 2010. Post your results to see if it works for others please. I know everyone is tired of chasing their tails on this problem and even posted fixes have
been so vague that you need to be a software engineer to follow them. If you have other fixes for this I know everyone would appreciate people posting all the steps from the beginning to end and assume that we know nothing at all. Post all the
paths and explanations in simple terms please.
I hope this helps.

BEFW11S4 - Constantly prompts for password submission and always fails

I decided to do a full reset (45s button on back). I promptly reset the admin password on first login. All subsequent "APPY" actions in the admin console forces me to a popup login screen where I have to enter password. This always fails and eventually I'm redirected to a 401 page (see below). For example if I want to disable wireless or set a WEP key on the main page a popup appears for password but it always results in a 401. I've tried clearing all browser information and attempted this on both IE 7 and Firefox 2.0.0.9 with similar results.
1. I don't remember always getting prompted for password before; after initial login.
2. Popup submission of password on subsequent authorizations always results in a 401.
Thanks in advance!
" 401 Authorization RequiredThis server could not verify that you are authorized to access. Either you supplied the wrong credentials(e.g., bad password), or your browser doesn't understand how to supply the credentials required."

I managed to fix this...
I found another support thread that indicated "disabling" Norton Internet Security prior to accessing the Linksys console. It appears NIS was filtering or preventing the username/password being sent in the clear.
How I did it...
1. Right click the NIS icon in the desktop tray.
2. Select "disable" NIS from the menu and enter a time from the drop-down (i.e. 5 minutes).
3. Return to IE. Clear all cached data (just in case).
4. Proceed to login to Linksys!
Cheers

After Migrating To Exchange 2013 All Outlook 2010 Users Constantly Prompted For Password (BUT OUTLOOK WORKS).

I have two servers. One is Exchange 2010 and the other is Exchange 2013.
Three of our users had mailboxes on Exchange 2013 for the last few weeks with no problems. They used Outlook 2013 and Outlook 2010. After moving the rest of our ~25 users to Exchange 2013 the users with Outlook 2010 began to be prompted for their
password constantly.
They try entering it and it immediately reappears.
The odd thing is it shows connected and they are able to send and receive emails correctly.
I've tested our exchange connectivity using www.testexchangeconnectivity.com and all is well there.
I'm not really sure what's going on.
Any help is appreciated.
Luke
Thanks, Luke Pickard

This can appear if Outlook clients are trying to connect to OAB virtual directory, and don't succeed for some reason. Mailbox and mailflow will work, but password prompt will appear when Outlook tries to contact OAB. Try to investigate in that direction.
Also, perform Outlook Configuration test (right click Outlook icon in task bar while holding CTRL and select Test email autoconfiguration.

Exchange 2010 mailbox prompts for authentication to Exchange 2013 mailbox

I am in the process of a 2010 to 2013 migration. The only issue I can't seem to manage is an authentication issue with Outlook 2010. My Outlook profile consists of my Exchange 2013 mailbox and a shared mailbox on Exchange 2010. Initially, Outlook was prompting
for authentication to the Exchange 2010 mailbox. Regardless of whether I entered the correct credentials or simply cancelled the prompt, I still had full access to both mailboxes (including Public Folders on 2010). The authentication prompt was removed with
the following command:
Get-OutlookAnywhere -Server my2013exchserver | Set-OutlookAnywhere -InternalClientsRequireSsl $true
The second issue I now have is the reverse of the above: an Exchange 2010 user is prompted for authentication to an Exchange 2013 mailbox. How do I begin to troubleshoot this problem - should I run the same command (above) on 2010? I don't quite understand
how Outlook communicates with Exchange but I am thinking there is an incorrect setting on one of the Virtual Directories(?).
Many thanks.

Hi Dennis,
Please open Outlook - press CTRL key - right click on the Outlook icon from right bottom corner taskbar –Connection Status to check the connection for your Exchange 2010 mailbox with shared 2013 mailbox. The following example in my test results:
Please check your connection authentication. We can run the following command to set your Outlook Anywhere for Exchange 2013:
Set-OutlookAnywhere -Identity "E15-01\Rpc (Default Web Site)" -InternalClientAuthenticationMethod Ntlm -ExternalClientAuthenticationMethod Basic -ExternalClientsRequireSsl $True -InternalClientsRequireSsl $true
In Outlook side, please ensure the following settings in Account Settings:
In Security tab, make sure Always prompt for logon credentials is unchecked and Logon network security is set to Negotiate Authentication.

Outlook 2010 keeps prompting for password every morning

Hi,
We run Exchange 2007 on Windows server 2008. All SP and updates are up to date.
About a month ago, two users got prompt for user credential in Outlook every morning, but other users in the domain are fine. Below are what I have tried but no help.
1. Deleted user credential for Outlook in Credential Manager
2. Recreated Outlook profile
3. Disjoin and rejoin their computers to the domain
I can repeat the problem on another computer with the user's account log in.
The problem only happens in the morning, once the user entered the credential, Outlook starts to update new email and it will be fine for the rest of the day.
Only two users have this problem. I can't figure out if they have anything in common. Since I can repeat the problem on another computer, I assume this problem should be related to user account.
I need help!
Thanks in advance!

Hi,
As per the information and details provided by you, to solve the Outlook 2010 password problem, please follow these steps: -
Firstly, you try to
change the profile.
Open Control panel/Mail/Select the profile and click Properties.
Select the mailbox and click the
Change button.
When inside the profile you will see tabs at top for
connection and security.
Please make sure you have selected
Negotiate authentication, and have unchecked the box that states
Always prompt for login credentials.
Then check if you are using
HTTP to connect with exchange, if so uncheck this and apply the changes.
Close Outlook if open and reopen Outlook.
I hope this information will be helpful for you.
Thanks and regards
Shweta@G
Hi Goyal,
Thank you very much for your reply. The Outlook settings are the same as you described. We do use HTTP to connect to Exchange. I unchecked it and see what happens tomorrow. but just FYI. All Outlook has the same settings with HTTP connection checked. Only
two specific accounts have the credential issue.
Will update you tomorrow.
Thanks,
Grace

Outlook 2013/Exchange 2010 Free/Busy access issues.

Good Day Everyone,
I am running a Win 2008 R2 environment with Win7 users, using Exchange 2010 and Outlook 2013. Last week my users started experiencing issues with being able to view Free/Busy in the Calendar for any other user. I have checked past issues with this with patches
KB 2837618 and KB 2837643. Neither patch is showing as installed and I have tried a nummber of the suggested fixes offered for that issue to no avail. OWA seems to be working just fine.
Our Outlook version is: 15.0.4605.1003
I need a fix for Outlook users and since I havve 140 users, individual fixes are a not realistic option.
Any assistance would be greatly appreciated.

Hi,
Please test if Out of Office feature works well in Outlook. If Out of Office doesn't work either, it should be Autodiscover related.
Once Autodiscover has not been configured properly, the Free/Busy information may not display correctly. If you are also seeing issues with Out of Office assistant, we may assume that you haven’t correctly setup Autodiscover, since these two symtoms are
common when Autodiscover is not configured correctly.
To verify that, please test Outlook Autodiscover Connectivity:

Outlook 2013 / Exchange 2010 Calendar Invitations blank on recipient side

We have Exchange 2010 and Outlook 2013 for our clients. When our users send calendar invitations to external recipients, some of the recipients are receiving regular emails just containing the notes field and subject. Specifically, when we email
a @hotmail.com or @outlook.com address this occurs. However, when we send an external calendar invitation to @gmail.com, the recipient can see it as a calendar invite and reply with an accept/tentative/decline.

How is everything so far?

Outlook 2013, Exchange 2010 error with Rules and Alerts

Hello,
I was recently informed by a user that when they open Outlook 2013 and click Manage Rules and Alerts, they get the following message:
By the way, NO Microsoft, this information is not helpful. Anyways, I found that the same problem is happening in my Outlook as well. I do not believe it is happening to all users' accounts, and I am able to set up Rules within Outlook Web Access,
so it seems to be some local setting. I found a lot of forums suggest running the Outlook /cleanrules switch, and this did not fix the problem. Other suggestions are to delete the profile on the computer and/or uninstall outlook and reinstall it.
I don't like these solutions, as they don't point to the true source of the problem and do nothing to help avoid this problem in the future. Has anybody else had this problem and been able to fix it? We are running Exchange 2010 in our environment,
although not sure if that makes a difference or not. Any answers that do not suggest the things I have already mentioned would be greatly appreciated!

Hi,
For this issue, I recommend you ask in Office forum which is staffed by more experts specializing in this kind of problems. You might get better help there.

Outlook 2013/ Exchange 2010 User Mailbox reached Limit and OWA is not reachable

This topic first appeared in the Spiceworks Community

Hi,
I suggest to repair .ost file to check this issue by the following steps:
Exit Outlook.
In Control Panel, click or double-click Mail.
In the Mail Setup dialog box, click E-mail Accounts.
Click the Data Files tab, select the Exchange account, and then click
Open File Location. A file explorer window opens to the location of the data file for the Exchange account. The
Account Settings and Mail Setup dialog boxes will remain open, behind the file explorer window.
Close the Account Settings and the Mail Setup dialog boxes, then return to the file explorer window.
Important: be sure to close these two dialog boxes before you delete the file. If they aren't closed, Windows may display an error message about a conflict.
In the file explorer window, right-click the Exchange data file and then click
Delete. The next time you start Outlook, a new .ost file is created for the account.
Best Regards.

Surface + Outlook 2013 + Exchange 2010 + VPN Problem

Ok so the Surface with Outlook 2013 works fine with our Exchange setup when the machine is attached to the network directly. Once it is on an external network and attached via a VPN connection it ceases to operate, and attempting to run Outlook simply results
in a box asking for credentials, which even when typed in correctly are not accepted.
We use many other laptops that are running Windows 7, and a couple that are running Windows 8.1 in the exact same manner, and they operate without issue.
Any ideas?

Hi,
May I first know your Surface version?
If you are not using Surface RT, I suggest you try this:
In Outlook, go to FILE -> Account Settings -> Account Settings -> Double click on the account name -> More Settings -> Connection -> Exchange Proxy Settings -> We can find under "Proxy authentication settings", there are "Basic
Authentication", "NTLM Authentication" and "Negotiate Authentication", I suggest you try "Basic Authentication", then click "OK". Other two authentications can also be tried if the "Basic Authentication"
doesn't work.
I hope the information is helpful.

It's recommended to download and install
Configuration Analyzer Tool (OffCAT), which is developed by Microsoft Support teams. Once the tool is installed, you can run it at any time to scan for hundreds of known issues in Office

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.

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

I
am currently thinking that this may be the error. Is there a way to
change the first failing result to the hostname of the
exchange13.company.local without breaking the current settings for the
exchange10.company.local autodiscover?

Outlook Clients for Exchange 2013 Prompt for Password

I have a co-existence of versions 2007 and Exchange Server 2013 CU2 and currently have the following problem:
- Customers now where I performed the migration to the 2013 version, when starting Outlook is always asking for password. The settings for Outlook Anywhere are as follows:
RunspaceId : b43cd829-a81f-4b00-bb4d-73389c9df50d
ServerName : EXCH-HTCA13
SSLOffloading : False
ExternalHostname : webmail.first.pt
InternalHostname : exch-htca13.first.pt
ExternalClientAuthenticationMethod : Basic
InternalClientAuthenticationMethod : Ntlm
IISAuthenticationMethods : {Basic, Ntlm, Negotiate}
XropUrl :
ExternalClientsRequireSsl : True
InternalClientsRequireSsl : True
Can anyone help me identify the problem?

Hi,
Agree with Andy,you can change the ExternalClientAuthenticationMethod to NTLM,
In addition, I recommend you refer to the following article:
