Issue - Programmatically posting WSS 2007 Discussion List Items shows sender as "System Account" in Outlook 2007

 

  • I have been working through some hardware issues so Part two of my SPSreport blog continues to hold , but I wanted to take a few minutes to share some findings from a recent case with you.

  •  

  • In this case, our customer is a programmer who sent in some code wherein he was programmatically setting the Email Sender and From field in WSS Discussion list items using OM code like this:

  •               

  •                 SPListItem discussion = SPUtility.CreateNewDiscussion(list.Items, "subject");

  •                 discussion[SPBuiltInFieldId.Body] = "body";

  •                 discussion[SPBuiltInFieldId.Categories] = "category";

  •                 discussion[SPBuiltInFieldId.EmailSender] = "SenderEmail@email.com";

  •                 discussion[SPBuiltInFieldId.MessageId] = "Server Internet Message ID";

  •  

  • As most of you know, I describe myself as a "code toddler"; I can read some code, I can write "Hello World" in a couple of languages. So I didn't know if I would be able to help our customer… but I knew I needed to try to do so. And I can understand that the code above should be setting values on specific columns and fields for a Discussion Board item. So off we went!

  •  

  • The above code shows the proper person, as pushed from the OM into each of the appropriate custom columns in WSS's UI. But from the other side of this issue, after a sync to Outlook the From column is the Creator of the post as shown in the Outlook UI, i.e., the person that ran the code in SharePoint. In our case, this was the system account.

  •  

  • In my initial research, I found a couple of OOB reasons why we might see the System Account as the sender. First, of course, is if the Creator of the post is the system account (never discount the obvious!). Second, if you see content in the document library that is assigned to the system account, it sometimes means that the document library has treated the incoming mail as an anonymous user due to the inability to resolve the name in the list of users with rights to submit mail to the list. To check to see if this was the cause of our issue, we checked to see if  the library was set to accept mail from all senders. You check this from WSS by browsing to the Discussion list, then choosing Settings > Discussion Board settings > Incoming Email Settings (and then navigate to the bottom of the page). Neither of these was the case when we checked them…

  •  

  • To reset: the code makes the "poster" looks good on the Discussion Board list item, but on the sync to Outlook, the From field is changed to the WSS System Account. Nothing left to do but break out the troubleshooting tools! For this issue, my weapons of choice were netmon, Outlook Spy and source code for SharePoint and Outlook (sorry, no links for these :)). 

  •  

  • I set up an OOB Discussion list (modified the theme, thus the difference in color), added a column (blue), started netmon and performed an Action > Sync to Outlook from the list.

  • When I look at the same message as rendered in Outlook, and specifically the MAPI properties, with Outlooks Spy, I see this:

  •  

  •  

  • In all, I see 4 MAPI properties with my name on them. I then went to a source search on each term. Ows_editor yielded one hit in Outlook source; he is responsible for conversion of the incoming ows_editor parameter. The conversion goes to the MAPI properties of PR_LAST_MODIFIER_NAME and PR_SENT_REPRESENTING_NAME; this

  • In all, I see 4 MAPI properties with my name on them. I then went to a source search on each term. Ows_editor yielded one hit in Outlook source; he is responsible for conversion of the incoming ows_editor parameter. The conversion goes to the MAPI properties of PR_LAST_MODIFIER_NAME and PR_SENT_REPRESENTING_NAME; this is hard-coded. Searching source for ows_author yields that "Created By" in WSS maps to PR_ORIGINAL_AUTHOR_NAME_W. This is exactly confirmed by the Outlook Spy results above. So these are hard coded and cannot be modified simply by stamping a WSS property on them programmatically.

  •  

  • I then went through that same set of steps after adding a column called blue. When I viewed the trace, there was no ows_ property associated with the column that would be translatable by Outlook. So again, another thought, and another dead end.

  •  

  • Then my customer asked a question - "How do I add users to SharePoint that aren't in my domain". Having worked with contact lists in SharePoint, I knew that this is very simple; you just need to add a contact name and email address; there is no requirement from SharePoint that your contact be from your domain! And yes, from other work with our STSADM command line Administrative tool, I also knew that SharePoint will also recognize a local account of the SharePoint box as a valid user as well. This last piece of information is just what my customer needed.

  •  

  • With this piece of information, he wrote the code in WindowsAccount.cs, tied that in with WSSAccount.cs, and boom! A solution is now in place that is allowing him to use SharePoint and Outlook interoperability to programmatically list SharePoint posts and have them sync to Outlook as he wishes. This is a fantastic example of a code toddler like myself using wide product knowledge in the Microsoft Office Family and troubleshooting tools to help an experienced programmer build a custom business solution. Everyone wins when this kind of synergy happens!

  •  

  • Sample code attached with customer's permission! He reviewed ths blog before publishing as well; his desire here is that someone else might benefit from our work. All typical disclaimers apply, the code is not supported by Microsoft, nor myself - use at your own risk/benefit, etc...

  •  

  • Have a safe and happy holiday!
