Outlook 2010 breaks functionality


I have installed your Solution on our Sharepoint 2010 (German) and everything has worked for me using Outlook 2007.
Now i have installed Outlook 2010 and it breaks the funktionality.
Now i only receive the Errormessage (shown in the attachement) like: "You have not enough rights to..."
We have tested it on 4 Machines.
2 with Office 2007 -> It is working
2 with Office 2010 -> Errormessage

Hi - we had also to deal with this problem, but in fact it had nothing to do with Outlook 2010 (which we used before without problems) but rather with a new domain used by the SharePoint. The problem was, that the new domain hadn't been defined as "Trusted site" in Internet Explorer.

Steps to define the SharePoint Site as "Trusted site" in Internet Explorer:
  1. Click on "Tools" in the task menu of Internet Explorer
  2. Click on “Internet Options” from dropdown-menu
  3. In the internet options click tab ”Security”
  4. Choose the zone ”Trusted sites”
  5. Click the button “Sites” and insert your SharePoint-Site to “Trusted sites”.
  6. Click the button “Custom level”
    6.1 Activate the setting “Initialize and script ActiveX controls not marked as safe for scripting”
    6.2 Activate the setting “Automatic logon with current user name and password”
Better close and reopen Internet Explorer after executing the steps above.

Could you keep me informed whether this solved your problem?

As an approach to solve the problem please try the following:
  1. Click on "Tools" in the task menu of Internet Explorer
  2. Click on “Internet Options” from dropdown-menu
  3. In the internet options click tab ”Security”
  4. Choose the zone ”Trusted sites”
  5. Click the button “Custom level” and there for ALL settings click "Activate" (better make a screenshot of your current settings before...)
  6. Close and reopen Internet Explorer
  7. Try using the feature and if it works, reset the activations little by little to see when it crashes

same problem for me, no problem with Office 2007, but with Office 2010 I get the error message ...

A very important precondition is that the client computer (with Outlook installed) has to be located in the same domain as the SharePoint server. Did you check this and is it ok? If so: Did you already try the suggestions written on Aug 03?

Hi Communardo,

I have the same problem discussed in this post. Because I am SP admin I have a slighty different version of Outlook and other office applications. The webpart works like described for our user still using Office 2007, but on Office 2010 I keep getting this error message.

The site is added to the Trusted sites and the option required are enabled. Still no go.

With regards,

Hi Communardo,

I did try the comments from 03 aug, but it just keeps giving me the error. There is no domain differance. Any other idea's ?

With regards,

Hi tjeerddebruijn,

I tried to reproduce the behaviour but in our test domain the feature works as expected. However in another domain I realized that in IE security settings for „Local intranet“ zone the same settings should be applied as described for „Trusted sites“ in the installation documentation. So hopefully this will solve your problem - please give feedback if so.

Hi Communardo,

I am encountering a similar problem.

When working with outlook (2003 to 2013) on the same machine where the Sharepoint Server is installed, everything works just fine.

But as soon as I try to send email with attachment with outlook 2010 or 2013 from another machine in the same enterprise domain, I get an error message stipulating that I :
don't have the appropriate permission to perform this operation
I have double checked the configuration on this machine (IE Internet Options, etc.).
From what I found out in this thread:

It could be an issue with outlook (2010 and onwards) refusing to attach files from distant URL comming from a non trusted location. This would work fine on the Sharepoint Server as it is trusted, but as soon as we use a different machine, the error occur.

But I am not sure anymore because I tried replacing directly in the code the file URL from the Sharepoint Server by a static image url from the internet and it works just fine even on the other machine. As I don't think this static url comes from a trusted location I don't know anymore.

Could you please help me on this matter?

Thanks a lot for this product and your insight.

I just once more tested the case (in the mean time using Outlook 2013) - the feature functions properly under the following conditions:
  • SharePoint server and client computer are in the same domain (NOT necessarily on the same machine though)
  • using Internet Explorer on client computer (in my case: IE9, but I don't think the version makes any difference)
  • the url to the SharePoint server (for example is contained in zone ”Trusted sites” in Internet Explorer options (tab "Security") on client computer (in my case this is managed globally via GPO but this either don't make any difference)
  • SharePoint uses Windows authentication i.e. the user in SharePoint is the same who is authenticated in Outlook (i.e. the current logged in Windows user)
Please check the url of the document you are trying to send as mail attchment. The "root" of this url HAS TO be contained in zone ”Trusted sites” in Internet Explorer options "Security" tab on your client computer.

Sorry attachment hasn't been uploaded - apparently a Codeplex problem...
