Access to Exchange inbox via MAPI in .NET

Posted By:      Posted Date: August 28, 2010    Points: 0   Category :.NET Framework
Hi Guys,   I have a client that requires a program to download messages from multiple users mailboxes on an Exchange server 2003. They will not enable IMAP or POP3 and have requested that I use MAPI for connection. Outlook will not be installed on the PC that this service runs from. They will be upgrading to Exchange 2007 or 2010 within 6 months, so the solution needs to work for Exchange 2003/2007/2010.   Are there any MAPI libraries (free or commercial) that I can use to accomplish this?

SQL and Outlook: Enable Database Access and Updates Through Exchange and Any E-mail Client


Using Microsoft technologies, you can insert, edit, query, and delete database entries using any e-mail client such as Hotmail, Outlook, Yahoo, or even WAP phone. While e-mail is certainly a powerful and widely used tool, it is usually not integrated with an application for performing any tasks other than sending reminders. The application scenario described here, an e-mail-based SQL update program, uses a simple data model; however, this solution will apply to any data model that you are working with. It will also eliminate the need for complex n-tier Internet applications and serves as a low maintenance solution for providing data access.

SharePoint 2010 - "My Inbox"(OWA) webpart not working with Exchange 2010

Hi, I'm trying to setup the webpart "My Inbox" (OWA) in SharePoint 2010. It works when connecting to OWA running exchange 2007, but failes with error 400 not found when connecting to OWA running Exchange 2010. The error appears after logging in.  I'm using this url: https://<exchangeserver>/owa I assume that this should be supported by Exchange 2010, but it seems to fail using this parameter /?cmd=contents. Any suggestions?   Best regards, Petter

Exchange 2003 Inbox and Calendar webparts for MOSS 2007


I've created one Inbox and one Calendar wepbart as descibed here:


using  OWAInboxPart and OWACalendarPart (code below).

When deploying them and placing them on the same page, only one of them will show anything. It looks like the last added webpart works, while the other won't.
If any one of them is placed alone on a page, they work as expected.

Does anyone know how to make them work togheter on the same page?

Thank you for your time!

Best regards,
Hans Erik Storeide

Querying Exchange Server 2003 does not bring all fields in Access 2007


Hello everyone.

I'm importing Outlook contacts shared folder to Microsoft Access 2007, but I can't see all the fields in each contact, what I have done is:

1. Open Access 2007

2. Click in "External Data" and make a Link to Outlook

When I do this, Access brings to me several fields but I can't see ALL fields which I can see in Outlook contact form.

The default form to "add a contact" in Outlook has been modified by adding more fields, DropDownList, TextBoxes and mapping them to a specified storage field.

does someone have a trick to import ALL Outlook contact fields?

thanks in advance.

MVC architecture in ASP.Net using C# and Microsoft Data Access Application block

The Model-View-Controller (MVC) pattern separates the modeling of the domain, the presentation, and the actions based on user input into three separate classes [Burbeck92]:

Model. The model manages the behavior and data of the application domain, responds to requests for information about its state (usually from the view), and responds to instructions to change state (usually from the controller).

View. The view manages the display of information.

Controller. The controller interprets the mouse and keyboard inputs from the user, informing the model and/or the view to change as appropriate.

Store and Display Images from MS Access Database Using C#

There is only the difference of coding syntax to stream the binary data of image content type to upload it into MS Access Database using C#/VB in ASP.Net 2.0

Wrong Account being used to access files - Help - No Impersonation


I run a simple .aspx website on a Windows Server 2008 machine.

There is NO impersonation, and System.Security.Principal.WindowsIdentity.GetCurrent().Name returns NT AUTHORITY\NETWORK SERVICE, which it the account which the application pool runs. In my web.config, I have <authentication mode="Forms">.


I tried to test the security of the application and server by removing file permissions to the .aspx files. I was greatly worried when the website continued to run without problem (it should not have been able to read the .aspx files).

By turning on file level auditing, I discovered that the .aspx files were being read by the machine$ account (if the machine is called Serv1, then the files would be read by the Serv1$ account, which seems to have access to all files on the local machine).


Is this a security breach or is this behaviour by design ?

Please can somebody assist, as I am worried.

Disallow Direct Access To Files



Here is my dilema, on my site i have a WordPress Audio player (http://wpaudioplayer.com/standalone) that plays my mp3's.

It loads the Mp3's in by javascript...example below:

       AudioPlayer.embed("audioplayer_7", { soundFile: "/Files/Music/[name of file].mp3" });

This file name is clearly visible in the browser source. Not a problem, however this means that any user can legitimately browse to the file directly and download it.

Now i still need the mp3 player (which is flash) to have access to the file but if a user was to try accessing the file directly, they would not be allowed access to it.

I am not sure how to go about this, i am circling the idea of a httphandler but not sure if this is sufficiant to stop the direct access to the file.

Any help would be appreciated

Access SessionState: via App1 to SessionState from App2


Hi .NET'ers,

i'm interested to do the following - i geuss, i have no option to do that:

we have our "mainapplication" on a DB; we are tracking user-login status by switching a bit in the DB in the users data row.

we hvae a second application, the backend, which is the administration tool.

(the applications are put in seperate diretories on HD)

sometimes, we need to block/ban users. in some cases the users are logged in, when we "see them in action".

i'd like to build a button in the backend-application, which logss-out the user from the mainapplication.

for sure: i can access the same DB and switch the bit to "know" he's offline, but this will not kill the session on the mainapplication.

because: if a user is on/offline is also indicated by the session in the IIS.
and as the IIS-session is active, the user may be already banned - but he will not be logged out automatically (and showing something like "you have been logged out because of a ban)

one option would be to call the DB by each page-load to find out, if the user is logged on.

is there any option to implement this?

Help with me AD access in Asp.NET + C#


Hi All,


Need a help..

I have deployed a asp.net web application with integrated windows authentication mode on.

The requirement is that.. few menu options will be visible to end user based on their role..So I am getting the loggedin user identity and then checking for group of that user..

I implemented this code and it is working fine. I am getting the list of groups user is associated with.

Recently we decided to give access to the student user group also which is the most restrictive group out of all..

we gave folder read folder permission to application folder and when tried to access the site, it is asking for username, password again and again and some times randomly it gives error:

Computer name could not be obtained.

Can anybodly please help me to understand what is the minimum permissions required to a AD user group to acces a windows authenticated asp.net site?




Using windows authentication to access SQL when using ASP.NET 4.0 via COM+


I am using SQL Server 2008 under windows authentication, front end is ASP.NET which uses COM+ to access database.

COM+ components are configured to run as domain user.

When looking through the logs (SQL Profiler), I can see the login name as the configured identity instead of windows indentity.

I have got Website running under "Intergrated Windows Authentication" and database is running locally on webserver.

Web configure contains entry for <identity impersonate="true"/>.

My connection string is

connectionString="data source=db01\test01;initial catalog=test; integrated security=SSPI;persist security info=False; Trusted_Connection=Yes"

Any ideas?
