Meeting requests received in public folder not forwarded to users mailbox/calendar

Hi,

we have a somehow strange issue on SBS2011 (Exchange 2010/Outlook 2010) here. We receive our EMails using the SBS POP connector, where emails are forwarded to a public folder. This works pretty well (for normal emails), but meeting requests (altough correctly displayed in the public folder) show the following:

• "As the meeting organizer, you don't need to respond to the meeting."
• All meeting buttons "accept", ... are greyed out
• "The meeting cannot be found in the calendar"

If we manually forward the meeting request from the public folder to a users mailbox, then suddenly the buttons are enabled again and everything is working as with an internally send meeting request.

So the questions are:

• Can we somehow make those kind of meeting requests work in the public folder?
• If not, can we automate the forwarding action to the corresponding users?

Thanks!
