Users can delete SharePoint 2010 Discussion posts from Outlook 2010

Posted By:      Posted Date: April 10, 2011    Points: 0   Category :C#

I have setup Discussions on SharePoint 2010 and users have linked these discussions to Outlook 2010.  Permissions on the discussion board are setup such that every user is a contributor (i.e. they can post messages).  On SharePoint, the permissions seem to work properly; that is users can post messages and delete/modify their own messages.  However, within Outlook, users can delete anyone's message. We just had an incident where a user deleted ALL messages in his Outlook SharePoint list and it deleted all messages from the SharePoint site too.

Is there a permission setting that I don't have set properly?

Thanks for your help.

reading sharepoint 2007 discussion board entries in outlook 2010 sometimes deletes or reposts them.


I get a huge fire alarm every month or two. Our users like to post and receive all the SharePoint lists from Outlook, but sometimes there will be mass reposts of old items, or deletion of mass items when they aren't even logged into SharePoint, or deletes a mass of discussion board entries when (again) the user isn't even in SharePoint nor deleted them from Outlook. I can't recreate the issue, and it seems completely at random. Any ideas what I can do to recreate, fix, or find out what is causing this?

This is a really big issue.

Its a MOSS 2007 server with Outlook 2010, and they are connected (Actions -> Connect with Outlook).


Outlook 2010 / Sharepoint authenthication issue


Hi all,

I'm using Outlook 2010 on Windows 7 64bit.

My company uses a hosted Sharepoint server (I guess it's Sharepoint 2010). There's a team calendar, which I would like to connect to my Outlook 2010. Linking it to Outlook works fine until it tries to update the calendar with the Sharepoint server. I shows the following error:

Error (0x80070005) when running the task "SharePoint": "You are not authorized to view the SharePoint list (team calendar). Contact the administrator of SharePoint site. HTTP 401."

So this tells me, I'm not authorized to connect - which is quite clear because Outlook never asked my for any username or password.

Funny thing is when I try to add an internet calendar (Right mouse click on calendars, Add calendar, Internet calendar) and use the url of the sharepoint list, it asks me for username and password, but then fails to add the calendar, as it isn't a webcal (which is OK).

BUT: As Outlook at this moment has the username and password, the exisiting Sharepoint calendar synchronizes correctly. This works until Outlook is being restarted.

Does anyone have an idea why I'm not asked for any authentication? Maybe there's some setting I haven't found yet? It works with trying to add the webcal any time when I start Outlook, but t

SharePoint Search Server 2010 Express returns no search results for non-admin users

This is going to sound crazy, but anyway... bare with me... I have a SharePoint Search Server 2010 Express (RTM) installed with a crawl account (call it sharepoint_crawl) which has full read permission to an entire site collection of 100,000 documents. I have logged in with this account to make sure it has read access to everything, and it does. I run a full crawl of all documents and allow it to finish. If I try and search the content for an extremely common term (i.e. 50,000+ hits) I get no results. However, if I log in with a site collection admin I do get search results. There are no indexing errors or query errors in either log files or event log. Everything looks like it is working correctly - just no results for non-admins Anyone tripped on this? I have recreated the crawl account and perform a full re-index with the same results. What gets me is that the crawl account does have read permission to the content it is indexing, the content is indexed correctly, but the crawl account cannot get results back. It is as if security-trimming is removing everything. Any ideas?

SharePoint 2010 Discussion Board



We are planning to start a discussion board / forum on our SharePoint environment. The default SP 2007 look and feel does not meet our requirements, we want a bit more user friendly look and feel. We will go to SP 2010 not long after release, can someone maybe post a print screen of an example of SP 2010 discussion board? Or extra info about the differences with SP 2007? Can find those on the internet.

Connect to Outlook feature in SharePoint 2010 still using .pst files?


The Connect to Outlook feature in SharePoint Server 2007 uses a .pst file to store content that is visible in Outlook. This has caused issues in the past with a client's enterprise policy of preventing use of .pst files on desktops. This particular client has an application that periodically checks for .pst files and deletes them, which breaks the Connect to Outlook feature for them.

Does SharePoint 2010 use the same functionality to Connect to Outlook, or something different?
