Creating Microsoft Defender AV Exclusions
Exclusions can be set on the account, organization, or host level (depending on inheritance settings).
To create exclusions on the account or organization level, click on "Configure" within the Managed Antivirus Status table on the Managed AV page of the Account or organization. After selecting inheritance settings (if available) you will be able to enter the exclusions.
- Path exclusions - type out the path you want to exclude (i.e., C:\ProgramName\Databasefolder)
- Extension exclusions - type the extension name of extensions you'd like to exclude from scanning (ie. .txt, .docx, etc. <-- don't exclude these)
- Process exclusions - type the full path of programs you'd like to exclude (i.e., C:\tester.exe)
