Can you do a rule to block them that way? Just a thought. I use rules to filter a lot of crap out of my inbox. -Scott -----Original Message----- From: MSU Network Administrators Group [mailto:[log in to unmask]] On Behalf Of Al Puzzuoli Sent: Tuesday, November 17, 2009 8:29 AM To: [log in to unmask] Subject: [MSUNAG] Fighting outlook Calendar Invite Spam? My director just got a spam calendar invite. The thing that makes this type of spam even more insidious than mormal is that by default, appointments are put on your calendar whether or not you accept them. I assume there is a way to set the calendar not to accept appointments by default, but is it possible to do something more flexible, IE, only accept appointments by default if they originate from the msu.edu domain?
