Login prompt when opening office documents in SharePoint 2010 library

Posted By:      Posted Date: September 24, 2010    Points: 0   Category :SharePoint

Environemnt : SharePoint 2010
Windows based authentication being used for site. All SharePoint servers part of the same network.

When i try opening office documents from document library( .docx, xlsx), SharePoint prompts for login credentials even though i am already logged into the website, worse part is that it prompts me for credentials for every document that i open. Also any files other then PDF opens up in the local machine's office application (word or excel) instead of in the browser.

I had migrated this webspplicatoin from MOSS and then did a visual upgrade as well to it, when i verified in the MOSS version of the site after i am log into the site ones it never prompts for login credentails ever when opening an office document.

Any body knows why this is happening.

Login prompt appearing when opening Office documents


Each time I open an Office document in a SharePoint library, I have to re-enter my credentials.

I am using MOSS 2007, Windows XP and IE 7.

I've checked the 'remember my password' option when being prompted for my credentials.


The strangest thing is even that when I press Cancel on the pop-up window asking for my credentials, the document is still opened...


I found already some posts around this matter and tried already following suggestions:

* I added my site to the trusted sites

* I checked that 'basic authentication' is unchecked under Central Administration -> Application Management -> Authentication Providers

* I've added my credentials for the server hosting the SharePoint environment in the managed passwords for my user account in the control panel (though I am not 100% sure of having this done correctly. It is asking upon entering an extra credential for a server name. I entered here the same name as the one appearing on top of the pop-up window asking for credentials, after 'connect to')


Opening .pdf, .zip files is not asking for the credentials. So it is only Microsofts own files which are creating the problem.

Sharepoint 2010, Constant prompt for credentials to edit office documents in a fqdn setup


Is there a solution to resolve the constant "Prompts" For user id's and passwords when a person tries to open/launch/edit office documents from sharepoint 2010.

My setup: sharepoint fqdn in the domain sp.domainname.local, The sharepoint server is a member of this internal domain. In dns I have local zone of sp.domainname.com with a cname that points to the internal sharepoint server. There is no issue in users accessing the server both internal and external, The issue arises when Office documents are launched from SP2010.

In central admin I have configured the alternate access mappings to be http://sp

I have also tried putting the fqdn dns name of the sharepoint server in IE8 trusted zone but
no luck, I still get credential prompts.

I think the issue might be that Office does not see that the files are coming from the fqdn of sp.domainname.com so hence the prompts.

Trying to fix this as right now its a total pita. I found some previous posts on this issue with SP2007 but found nothing that really addresses this in SP2010.

Thanks Paul

Long delay opening Word documents from SharePoint 2007 with Office 2010


The first time a document is opened it's fine, opens in just a few seconds.

Subsequently, there is a long delay (about 20 seconds) in the "Contacting server for information..." step.

This happens to all users and all documents, each one will open fast the first time then slowly the second and subsequent times (until, we think, the app pool is recycled - there is no schedules iisreset/reboot).

This does not happen when using Office 2007.

IE6 and 7 exhibit the same behaviour.

Visual C++ Runtime Library error when opening documents in Powerpoint 2010 from Sharepoint link



I posted this question on the Office Powerpoint forum and did not get much response so thought I would try here.   Here is the link to that post  http://social.answers.microsoft.com/Forums/en-US/pptshare/thread/36a58d07-b1ad-4935-a14e-086dae8cb786

I'm running Windows 7 with Office 2010.  We have a Sharepoint 2007 server.  Whenever I click a link from our Intranet site I get the error "this application has requested the Runtime to terminate it in an unusual way.  Please contact the applications's support team for more information."  It asks if I want to open in safe mode and I say yes and it never opens. 

During testing I also find that if I have a blank powerpoint .ppt file that I try to save to the same document library on the same site it works fine, but if I try to save a blank .pptx file to the site I get the same runtime error. 

This does not happen on all powerpoint or office documents being opened from the Intranet.  If I boot to safe mode it works fine.    If I copy the files local they work fine.  Any ideas on how to fix it?

Thanks so much!!!

Office 2010 will not open Office 2003 Documents on SharePoint

Going directly to a document in the document view and selecting any of them will present the Read Only/Edit prompt and when clicking Read Only Word or Excel 2010 depending on the document type will open to a blank page and just sit there. If you do a search and then click on the documents that are returned in the search results, it opens as expected.

Office 2010 can not integrate with Sharepoint Server 2010 document library, both RTM

Hi I have one standalone SharePoint Server 2010 and Office 2010 on Windows Server 2008 SP2. Both SharePoint and Office are RTM. When I create new document from the document library, it can open the Office Word.  When I save the document, Office gives me the local browser dialog other than remote sharepoint library. When I try to enter the sharepoint site url in the dialog, it tells me: path does not exist. On another machine, Windows 7, the Office 2010 RTM can open and save docs from/into the document library. There seems something wrong with the Office client. Maybe someone can tell me how to fix it. Thanks.

Publish Office 2007 documents with metadata to SharePoint 2010?

Hi. I have SharePoint 2010 Enterprise based Intranet solution. We are publishing office 2007 documents to various document libraries there. When uploading documents normally to the document library, I can enter managed metadata to the documents which are later sorted and filtered by this metadata. But how can I enter metadata at the point where I'm publishing the document(Publish->Document Management Server)? I can get the document management pane to show my metadata -column in word as a textbox after the document is published, but the textbox is colored grey and says that I should modify that data on the server i.e. from sharepoint.

Office 2007 Documents Open in Read-Only when Opening them from a WSS 2.0 Document Library

Hi, When any of our Windows 7 Pro computers that run Office 2007 Pro attempt to open a Word document that resides in a WSS 2.0 document library by using the drop down menu and selecting "Edit with MS Word", the documents open in read-only.  Our work-around is to save the document locally, modify it, and then save it back to the document library. We have some Windows XP and Vista systems that run Office 2007 and they are fine and can simply edit the document and save it.  We also have a handful of pc's that run Office 2003 and they are not having any issues either. Things I've tried: Office 2007 Repair - no luck Office Reinstall - no luck Some registry mod HKCU\Software\Microsoft\Office\12\Internet\OpenDocumentReadWrite=1 (noted on a MSKB article) - no luck and after re-reading the article it clearly states that this will not address content hosted on WSS or SPS sites Clearing IE temp files, resttting IE to defaults - no luck Once again, this only seems to happen to Win7Pro pc's that run Office 2007.  Honestly, I can't tell if IE8 has anything to do with this. Any thoughts or help would be extrememly appreciated. Thanks, Mike

Can't open SharePoint documents in Office 2010

Hi, I have a SharePoint 2010 standalone installation and a SP 2007 with SQL back-end installation for testing and proof of concept demonstrations.  All the servers are running Windows 2008 Server and are on a vSphere 4.0 ESX server as virtual machines. Most of the pilot team are on Office 2007 and are working fine with the installations.  I am running Office 2010 (not beta) and am unable to open any Word or Powerpoint files in a standard Project site's Shared Documents library. (I can open a word document stored and linked from a publishing site.) Whether I browse to the file or click the link in a search results page, Powerpoint and Word load up but before I get any login prompt or application screen appearing, the application crashes.  This occurs whether I open the document Read only or click the implicit check out 'Edit' button. If I check the document out to my local drafts folder I can open normally.  As I can't find anything about this on the internet I'm guessing it's not a common occurence!

Open Office Documents from Document Library without Password Prompt

We have a SharePoint site and Document library set up for anonymous access.   All non-Microsoft file types open correctly without a password.   When users click on Microsoft Office documents they are prompted for passwords.   Is there some way to configure the Office documents or Document Library so that users are not prompted for passwords when they open documents or is this a bug?

Currency and number column error with office 2007 document formats in SharePoint 2010 library

Hi there,



The following error occurred within a SharePoint 2010 document library:

As I tried to test out the new SharePoint 2010 environment I changed the metadata from a few documents within a document library. I noticed that the data from the currency und number field was incorrect from a few documents. The numbers looked like that the decimal separator were ignored. For an example: 123.456,78 was saved as 12.345.678.

At first I thought it could be a language incompabilty but if that would be the case: Why would there be other documents which show the correct number?


I created another document library to recreate this error. And there I noticed the real reason: Every time I changed these fields from a document which was saved in the office 2007 format the error occurred. The metadata from the documents in the office 2003 format were correct.


Has anyone a similar problem or got an idea how to solve this problem?
