Bloody microsoft crm

So, first make sure you have the right Plugin Registration Tool ( don't download one from microsoft!use the one from source in your sdk: 1h ), then make sure to change your discovery URL... not the one you used in other stuff ( as in, code VS2010 to access exchangeserver and stuff... not the same. "uh?" "exactly". 1h ): link

After that it is painless, just follow this one for including a plugin in crm.
