Create mailbox for user via webservice on remote Exchange 2007 server. (C #)

EDIT Yves got it almost by having and error message now that he cannot find the exchange DB. I start the service on another server, then Exchange, so I assume I need to use a UNC path. MyServer01 \ First storage group \ Database.edb mailbox is not working though ...

Hello! I'm getting frustrated here, feeling a huge headache and I'm almost ready to throw my computer out of the window ...

This is a problem, I want to create a new user in Active Directory via Sharepoint, a thread is started under the Sharepoint list that catches the variables and sends them to the web service that creates the user in the active directory. This works great, but the user also needs a mailbox. So what should we do? We set the mail property to the desired email address and found the "Create mailbox" property .... say what? where is it? NOOOOOESSS doesn't exist anymore, MS decided it should be more complicated and now the only way to do it is to use powershell shit ...

That is why I am here, I was looking for some information on this and found some code that should do the trick, but, and this is where I am stuck, the web service does not start on the Exchange server, and on another server, the webservice needsw to connect to the exchange server for running powershellshizzle ... can't find information on this, can't find any examples and so on ...

hlep ... F1 ... etc.
