In this article, I’ll show you how to disable the Exchange Server 2013 Anti-Malware which is enabled by default.
Disabling the Ant-Malware is done using the EMS and needs to run on a mailbox server, once you disabled the service the server will restart the transport service.
If you have more than one mailbox server this will need to run on each one of them.
To disable the anti-Malware go to:
C:\Program Files\Microsoft\Exchange Server\V15\Scripts
Run the following cmdlet:
.\Disable-Antimalwarescanning.ps1
To bypass filtering on a specific server run this:
Set-MalwareFilteringServer -BypassFiltering $true
