-Microsoft Exchange has supported integration with the Antimalware Scan Interface (AMSI) since the June 2021 Quarterly Updates for Exchange (see [Running Windows antivirus software on Exchange servers](/exchange/antispam-and-antimalware/windows-antivirus-software)).

 Many organizations exclude the Exchange directories from antivirus scans for performance reasons. Microsoft recommends auditing Microsoft Defender Antivirus exclusions on Exchange systems and assessing whether exclusions can be removed without impacting performance in your environment to ensure the highest level of protection. Exclusions can be managed by using Group Policy, PowerShell, or systems management tools like Microsoft Intune.
