Exchange Server 2016 - All Incoming Emails to Junk

    Question

  • I have recently installed Exchange Server 2016 and all incoming emails started going to Junk folder after installing Kaspersky Security 9.0 for Microsoft Exchange Servers

    Any hint whether this can be controlled from Exchange settings or Kaspersky?

  • Hi,

    On exchange side, if the message's SCL value is greater than the SCL Junk Email folder threshold that's configured for the organization or on the mailbox, the message is delivered to the Junk Email folder. To check the SCL Junk Email folder threshold for organization, try this command:

    Get-OrganizationConfig | fl *SCL*

    By default, this value is 4. For more information, refer to this document

    If this issue doesn't exist after disabling Kaspersky, I suggest to contact the support of Kaspersky for help.

  • Hi

    Did you set your exclusions for Kaspersky? Try disabling this AV and see if your problem disappears.
