Creating shared mailboxes with FIM2010R2

We need to provision, sync and deprovision shared mailboxes through FIM.

I have searched extensively, and found several places mentioning, that it is not supported by older versions of ILM/FIM. I also found mentions of it might be coming in the future, but the latest version of ExchangeUtils makes no mention of shared mailboxes.

I understand that we can always "just" provision using Powershell, but Powershell through manage code is something we try to avoid if we can.

So before we go down the bumpy Powershell road... Is there a better/other way to provision mailboxes in FIM 2010R2 than using powershell?
