MAPI over HTTP not working correctly, Outlook 2013 clients prompting for credentials during profile creation or opening depending on security of virtual directory

ENVIRONMENT
-1 Exchange 2013 SP1 CU7 server with all roles that is also a hybrid server with Office 365 tenant, mailboxes are all on premise only LYNC online is being utilized right now.
-Exchange 2013 public folders
-Mix of Outlook 2013 SP1 and Outlook 2010 SP3 clients all fully update to day as of Feb 2015
Outlook anywhere is working perfectly across all clients both internally and externally using autodiscover. Both Outlook 2013 and 2010 clients can open the program and create a profile automatically via autodiscover and no additional logon prompts
are seen.
We set the internal and external mapi virtual directory URLs to a valid URL that also matches the Exchange 2013 SSL certificate. We set the security to ntlm, negotiate on the mapi virtual directory. We reset IIS and enabled mapi over http in
the org config. We run in to problems here.
Outlook 2010 clients appear to be working fine. We can create a new profile and open and close Outlook without any logon prompts and verify that MAPIHTTP and Negotiate are used to connect to Exchange.
Outlook 2013 clients are having problems. As soon as we try to create a profile it says your administrator has made a change that requires you to restart outlook and then a windows logon prompt appears. If we authenticate Outlook will open and connect.
This logon prompt should not occur. We can confirm that it is connecting via MAPI HTTP and Negotiate.
If we set the mapi virtual directory to NTLM only then a logon prompt also appears during every open of Outlook 2013. We can confirm that it is trying to connect with MAPIHTTP via NTLM in the outlook connection test screen.
I do not understand this behavior by Outlook 2013 which was supposed to be designed with MAPI HTTP in mind. I would think the same issues would occur with Outlook 2010 but they do not. I am not sure how to resolve this and I am looking for help.

I have the same problem. Exchange and Outlook are both up to date. After creating a new profile Outlook prompts for username/password. A lot of users also get this prompt while
working - the profiles have been "migrated" from Exchange server 2010. <o:p></o:p>
Niko, as i can see in your screenshot you do not have Mapi over HTTP enabled. Why? You can change settings in the security tab – if you have Mapi over
HTTP enabled all options are grayed out (please correct me if I
am wrong):
This is a very annoying thing – does anybody else have the same problem?
Any suggestions on this?

Outlook 2013 Continually Prompting For Credentials

After migrating to Office 365 & installing Pro Plus 2013, Outlook 2013 (32-bit) continues to prompt for credentials even though it shows the mailbox as connected to Exchange.
To stop this prompt, I've done the following:
Removed Outlook credentials from credential manager
Removed/recreated Outlook profiles & renamed "outlook" folder found at C:\User\"username"\AppData\Local\Microsoft\ to "Outlook.old" so Outlook will recreate the folder upon restart.
Checked Security tab of "more settings" of the mailbox to make sure "Always prompt for logon credentials" isn't checked.
Please someone give me guidance as to what else the issue could be.

Hello,
How did you set the Logon network security under More Settings on the Microsoft Exchange
Security tab? Please make sure it's not set to a value other than
Anonymous Authentication.
To verify this, please follow these steps:
1. Launch Control Panel.
2. In Control Panel, locate and click
Mail.
3. Click Show Profiles, select your Outlook profile, and click
Properties.
4. Click E-mail Accounts, select
Account Settings and on the E-mail tab, click Change.
5. In the Change Account dialog, click
More Settings.
6. In the Microsoft Exchange dialog, select the
Security tab.
7. From the Login network security
dropdown, select Anonymous Authentication and click
OK.
8. Click Next and click
Finish, and then click Close on the Account Settings dialog.
9. Click Close on the
Mail Setup dialog, and click OK to close the Mail control panel.
Please let me know the result.

Outlook 2013 continually prompting for credentials on new domain

Greetings,
I first posted this in the Office365 community forums and was directed here.
We are experiencing an issue where Outlook 2013 (Office365 install) is prompting for user credentials every time it is opened, despite checking the option to remember the credentials. So far we've tried a number of troubleshooting steps, but nothing
has resolved the issue. The issue is happening to multiple users on multiple computers.
We are running:
Outlook 2013 (32-bit) (Office 365 install)
Windows 7.1 Professional (x64)
Computer is domain joined (Server 2012 R2 Domain Controllers)
Mail is hosted on Office 365
We've tried:
Clearing the Outlook and Office credentials from Credential Manager.
Removing the mail profile and the saved credentials from Credential Manager, then re-adding the mail profile.
We've tried adding the mail profile with both a manual configuration of the server settings and allowing Outlook to automatically configure them.
Ensuring that "Always prompt for logon credentials" is unchecked.
Setting "Always prompt for logon credentials" to disabled via registry (see
http://support.microsoft.com/kb/2984912)
Confirming that Autodiscover is able to connect (http://www.microsoft.com/en-us/showcase/details.aspx?uuid=e8db028a-06f4-45fb-aff1-e8ac896d29c5)
Deleting the Autodiscover.xml file so that it is recreated
Doing an Online Repair of Office 365.
Reinstalling Office 365
Recreating the user's Windows profile.
Ensuring all applicable Windows updates and Office updates are installed.
Changing Proxy Authentication from Basic to NTLM (will not connect with NTLM)
The machines this is occurring on are on a new domain that we are in the process of setting up. The user accounts are still on the old domain. Cross-domain trusts are set up in both directions and all other services are working fine. GPO settings across
both domains have been set up to be identical. The issue occurs on computers that were built directly on the new domain as well as computers built on old domain and migrated over. Machines that are not domain joined or are still on the old domain are not experiencing
the issue.
If any of you could provide any insight or other steps that we could try I'd greatly appreciate it.
Thanks

Hi,
For the issue that Outlook keeps prompting for password, I usually suggest users follow the steps in this article below, but apparently you have tried almost all the steps:
Why does Outlook keep prompting for password
I've seen some similar issues that were caused by an old "network driver", which for some reason caused a wrong server name to propagate up from the network layer to the application layer. Updating the network driver would fix the issue, I'm
not sure if this works in your scenario though.

Outlook 2013 Constantly Prompting For Credentials - Exchange 2007 - Small Business Server 2008

Hello, I am having a problem using Windows Small Business Server 2008 and Exchange 2007 with Outlook 2013. The issue is that a credentials box appears in Outlook 2013 when using there exchange account whilst connected to the domain. The box will randomly
prompt for user credentials, once the user credentials are entered it will either pop back up again and if you enter the details in again it will continue to pop up for around 4 or 5 times before accepting the credentials. It will then pop back up within 15
minutes and do the same thing, if you click "Cancel" on the box it will also go away and remain connected to exchange however a popup in the bottom right will appear asking for a password even though you can send / receive from the mailbox.
I have looked into this issue for hours and hours and still can not find a resolution, I have tried re-installing Office 2013 and re-creating the Outlook Profile as-well as as the Windows 7 Profile. I have checked through all the SSL certificates in IIS
and everything appear to be correct.
Is this a common issue? Is there anything I can do to further diagnose or fix this issue without having to try to re-install both the server and machine?

Hi James_wilson,
Any update?
Just additional, would you please let me know whether have installed all updates for Outlook 2013? If hasn’t, please install and then monitor the result.
Please also check if you enable
Always prompt for logon credentials setting in Outlook 2013.
If you enable this setting, please uncheck and check if this issue still persists. Meanwhile, please remove the old credential in
Credential Manager, then add again. Then monitor the result
By the way, please run the Exchange BPA on the SBS 2008 server and check if can find some issue.
Hope this helps.
Best regards,
Justin Gu

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.

Same problem here after restarting SBS 2008 for upgrades (annoying login box popping up after starting Outlook and also other times).
This solved the problem for me:

- SSL Settings / Client certificates - Stop / Start web server after changing settings:
Autodiscover: Ignore
EWS: Ignore
OAB: Accept *)
owa: Accept *)

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.

Outlook 2010 keeps prompting for credentials

Hello,
I have just about every user experiencing an issue with Outlook 2010 where Outlook keeps prompting for credentials. This has been happening ever since recent Microsoft Office updates that rolled out last week it seems. All my users still have connection
to the exchange server and can send/reply just fine. Issue occurs on both 32 bit and 64bit versions. This prompt will appear every few seconds and is becoming a nuisance for all my users.
I have attempted the following with no resolution:
- removed credentials from credentials manager
- ran Outlook in safe mode
- ran repairs on Office
- completely removed and re-added users Outlook profile (profiles are manually configured)
- made sure Office is up to date
- configured Outlook account on freshly imaged PC

Hi,
For this issue, you can first try some suggestions in this forum content:
Why does Outlook keep prompting for password
Especially try NTLM Authentication to check the result.
We have received some report about this issue since the February 10, 2015 update for Outlook 2010 (KB2956128). If you have installed this update, please note we have realized this issue and once there is any update, I'll let you know.

How to troubleshoot issues that Spell Check is not working in Outlook 2013

When composing a new message in Outlook 2013, we may notice that Spell Checker does not recognize misspelled words. When we enter a completely garbage word in Outlook, it won’t be marked as misspelled with a red wave underline. When encountering such issue,
we may follow the troubleshooting guide below to correct it.
1. Make sure you are not typing in the signature area.
Outlook doesn't perform a spell check in the signature area, so if this is the case, spell check won’t work. To confirm if you are typing in the signature area, right click in the area you are typing, if you see a menu listed all you signatures instead of
the normal context menu, then you are not typing in the email body.
If you want spell check work in signature area, use Quick Parts instead of Signature. For more information, see
Quick Parts.
2. Check the Set Proofing Language option.
In Outlook, click New Email to open a new message, click
REVIEW tab > Language > Set Proofing Language, a dialog titled
Language will open.
Please first make sure English (United States) is shown above the double line. If not,
you must enable the language for it to be available to check spelling.
Second, make sure “Do not check spelling or grammar” check box is not selected.
Note: If this method fixes the problem, repeat steps 1 through 3 to reopen to the
Language dialog box, and then click Set As Default.
3. Enable Check spelling as you type.
To enable the option in Outlook, go to File > Options > Mail, click Spelling and Autocorrect button. In the Editor Options dialog, select the check box labelled “Check spelling as you type”.
4. Make sure that you are not using a standalone version of Outlook or mixed versions of Word and Outlook.
The “Check spelling as you type” feature doesn’t work when using a standalone installation of Outlook or mixed versions of Word and Outlook. However, the manual spell check always works. In this scenario, we can set Outlook to
always check spelling before sending. To do this, go to File > Options > Mail, select the check box before “Always check spelling before sending” in the Compose message section.
5. A registry key exists overriding the spell checker
To remove the registry key, please follow these:
Important This article contains information about how to modify the registry. Make sure that you
back up the registry before you modify it.
a. Press Windows key + R to open the Run command.
b. In the Run box, type regedit, and then press Enter.
c. Locate the following registry subkey:
HKEY_CURRENT_USER\Software\Microsoft\Shared Tools\Proofing Tools\1.0\Override
d. Delete or rename the subkey.
e. Exit Registry Editor. Restart Outlook.
6. Recreate the NormalEmail.dotm and Normal.dotm template
If the two templates above are corrupt, this issue may also happen. To fix it, please browse to:
drive:\Users\username\AppData\Roaming\Microsoft\Templates
Rename the two templates, then restart Outlook to see the result.
7. Problematic add-in
Add-ins may cause various issues in Outlook, so if you have tried all the suggestions and still no luck, try starting Outlook in safe mode to see if a problematic add-in is the culprit. To do this, exit Outlook, press Windows key + R to open the Run
command, then type outlook /safe and press Enter. If the problem disappeared in safe mode, then go to File > Options > Add-ins and disable the suspicious add-in to resolve the problem.

Not all locales come with a dictionary installed for licensing reasons. 
If you do not have the en-US locale then check that you have a dictionary installed (Tools > Add-ons > Extensions) and selected. 
 
You can see which dictionary is selected if you right-click in a text area and open the Languages submenu. 
Also make sure that [X]"Check Spelling" in the right-click context menu has a tick. 
You can also try to toggle the "Check Spelling" item off and on again.

Hi,
Is the user using Gmail?
First, we need to confirm the account status is healthy, let the user logon Webmail to send and receive emails to check if there is any error.
Then, make sure the IMAP settings are correct as below:
Incoming Mail (IMAP) Server - Requires SSL
imap.gmail.com
Port: 993
Requires SSL:Yes
Outgoing Mail (SMTP) Server - Requires TLS
smtp.gmail.com
Port: 465 or 587
Requires SSL: Yes
Requires authentication: Yes
Use same settings as incoming mail server
Full Name or Display Name: [your name]
Account Name or User Name: your full Gmail address ([email protected]). Google Apps users, please enter username@your_domain.com
Email address: your full Gmail address ([email protected]) Google Apps users, please enter username@your_domain.com
Password: your Gmail password
Another possible cause is that the data file of this account has corrupted, I suggest you run Scanpst.exe to repair the data file(.ost) and check the result.
The default location of Scanpst.exe should be:
32-bit Windows
C:\Program Files\Microsoft Office\Office15
64-bit Windows
C:\Program Files (x86)\Microsoft Office\Office15
64-bit Outlook
C:\Program Files\Microsoft Office\Office15
Click-to-Run
C:\Program Files\Microsoft Office 15\root\office15
The data file location can be found in Outlook: File -> Account Settings -> Account Settings -> Data Files tab.
If the problem persists, I want to know what the error messages are. To protect the user's privacy, please send it to our email address:

Attachment don't open en previewer is not working in Outlook 2013

When i get office attachments in an e-mail in outlook 2013 on a windows 8.1 pro.
The attachments don't open. And the previewer of outlook tels me that the content can not be previewed.
Any one any idea what can be the solution to open and preview these documents?

Hi,
Did you get any error message when you try to open attachments?
What's the file type of the attachments? Can you open and preview a Word or Excel attachment in Outlook? By default, Microsoft Outlook 2013 blocks potentially unsafe attachments (including .bat, .exe, .vbs, and .js files) that can contain
viruses.
In addition, please try to clean out the Temporary Outlook Files folder to check if it helps. See:
http://www.howto-outlook.com/faq/securetemp.htm
Please let me know the result.

Send file as email not working when Outlook 2013 is default mail client

Have Adobe Reader XI 11.0.2 installed. Running Windows 7 Pro 64 bit with Office 2013 installed. When I set Default E-mail Application to Microsoft Outlook from Preferences I receive the following error trying to send any file as an e-mail:
"Either there is no default mail client or the current mail client cannot fulfill the messaging request. Please run Microsoft Outlook and set it as the default mail client."
I have toggled Microsoft Outlook 2013 off and back on as the default e-mail handler in the Default Programs of the Control Panel, but this has not resolved the issue.
I am guessing this may be a new bug since Outlook 2013 only recently came out, but if not, and someone has a fix, please let me know.
Thank you,
- Brian

Please try the steps mentioned at: http://support.microsoft.com/kb/813745 and check whether the issue is resolved or not.
If not, then try starting the outlook in safe mode using (Outlook.exe /safe) and check the issue again.
Hopefully, these will resolve your issue.

PDF printer not working in Outlook 2013

I have the PDF printer add in activated, but when I try to use the PDF printer in Outlook 2013, nothing happens.
The program turns for a while, but then closes without the PDF file being created.
Used to work without problem for earlier versions of Outlook.

You probably need to upgrade. According to the compatibility table (
https://helpx.adobe.com/acrobat/kb/compatible-web-browsers-pdfmaker-applications.html)
Outlook 2013 is compatible with Acrobat XI (11.0.1) or higher only.

Firefox Proxy Fail-over is not working correctly

I am in a corporate environment, where we must use a complex auto-proxy, by configuring an automatic proxy configuration of http://proxyconf/proxy.pac. I am seeing an intermittent failure with Firefox 3.6.13, where the same site will load after a delay in IE (e.g. it works for half an hour, then fails for a while, etc.).
By using Wireshark and tracing the packets, I have identified that a proxy server is intermittently failing, and Firefox is failing to try the second proxy. The auto proxy rule that is being invoked is:
if (!isResolvable(host)) return "PROXY 172.16.39.201:8080; PROXY 10.241.32.28:8080";
The problem is that Firefox is never failing over - it tries the 172 address 6 times in a row, then gives up and displays the "The proxy server is refusing connections" "Firefox is configured to use a proxy server that is refusing connections." "* Check the proxy settings to make sure that they are correct." "* Contact your network administrator to make sure the proxy server is working." error message. It continues with this behavior regardless of how many attempts, reloads, restarts are tried.
IE on the other hand will try and fail with the 172 address, and then start using the 10. address (which works correctly). Several other applications also work correctly, such as IRC clients.
Obviously the corporate proxy that is failing must be fixed, however Firefox is failing to utilitize the 2nd proxy after the first one fails.
Seems like a bug.
Is there some easy way for me to replace the proxy file with my own file? E.g. replace http://http://proxyconf/proxy.pac with file://c:\..., or use some add-on?
It must be an autoproxy script, as there is no single proxy that I can use for all addresses.

You can correct this issue by forcing the file blocklist.xml to update or wait until Firefox updates the file. 
That update will remove the severity="0" flags in the file that cause the problem.
See:
* [/questions/832793?page=2#answer-198407]
* http://forums.mozillazine.org/viewtopic.php?p=10899869#p10899869

Polling over https not working

Hi,
How do I change below to make it work with https? I tried with AMFSecureChannel but that did not work. Appreciate any help... thanks!
<channel-definition id="my-amf-poll" class="mx.messaging.channels.AMFChannel">
 <endpoint
 url="http://{server.name}:{server.port}/{context.root}/messagebroker/amfpoll"
 class="flex.messaging.endpoints.AMFEndpoint"/>
 <properties>
 <polling-enabled>true</polling-enabled>
 <polling-interval-seconds>1</polling-interval-seconds>
 </properties>
</channel-definition>

Hi
I think you don't need to do all these things. With default setting create a HTTPService component and assign the required url to it. You can assign the resultFormat.Call the send() method. Optionally you can pass argument to it.
Hope this helps
