I installed the Microsoft Exchange Server Standard Anti Spam Filter update V3.3.14422.478 on the 5th of January, 2015 and after a required reboot it appears as though many users, including myself are no longer receiving e-mails with attachments.
It is Exchange Server standard 2010, any ideas where I can start to trouble shoot? There were other updates installed on that date but they were for the windows server and IE 11, one for malicious software removal.
