Outlook Express SDK or similar

I has been asked to program a solultion, that look in
folders in Outlook AND Outlook Express.

The program are for a company that are not able to tell if their
users uses Outlook or Outlook Express.

Are there any way to disasample Outlook Express and put a interface in
Visual Studio ??

Regasm, midl, tmbexp etc....... ?

Kind regards

Normally you'd use tlbimp.exe on the dll files and create interop assemblies, but that doesn't work on MSOE.dll. midl only works for idl files, and regasm doesn't create interops. This, and the fact that the Microsoft Chat stated that they don't do OE API's, I think that it isn't possible.

Hmmm after typing the above I did a little search on google, and this is what came up:

First of all, if you are thinking Outlook Express, just forget it. The only three ways of integrating with Outlook Express are (and this is just me guessing) by paying Microsoft a lot of money and by giving them a really good reason to why you want to do that, or by hooking in through the encryption-entry, or by creating a proper hook and hacking your way in there.
I've done the hacking (due to missing funds) and it's not a pretty sight, it works but it's everything from clean.

So in short, no, it's not 'possible', sorry.

If you want you can ask to get your points refunded. Good luck.

Your best bet is to have a little chat with the project sponsor and explain why using Outlook Express in a business enviroment is not recommended.  Spending your time on convicing them to not use OE would be easier then making an app that will work with both (bascially two seperate apps).  As Razzie stated its not supported by MS, thus the only way to use .NET with it would be to "hack your way in there" which isnt fun or stable (ie, when the next version comes out it will most likely break something, and you will have to 'hack your way there" again :)

You should also be aware that Microsoft offers A LOT of free information to help people/partners sell their products, it shouldnt be hard to convice your client of the reasons for using Outlook.

Good Luck.

I recommend ACCEPT: https://www.experts-exchange.com/questions/21126110/Outlook-Express-SDK-or-similar.html#12026389 since it is not possible to accomplish what he wants.
