How can I block file attachments based on extension with Exchange 2007?
I want to block people from emailing zip files. Is there a rule or policy that I can apply on the Exchange Server? Any helpd that anyone can provide would be greatly appreciated.

Hi, Yes, you can use attachment filter to achieve the goal. For this issue, you can run these commands(on Edge Server) to block people from emailing zip files. Add-AttachmentFilterEntry -Name *.Zip -Type FileName Set-AttachmentFilterListConfig -Action -Reject -RejectResponse "The attachment you included in your e-mail message was not allowed. Your e-mail message cannot be delivered. Please remove the e-mail attachment, and send your message again." Here is a related article for you: How to Configure Attachment Filtering http://technet.microsoft.com/en-us/library/aa997139(EXCHG.80).aspx If anything is unclear, please feel free to let me know and I will be glad to help.
