Microsoft 365 Exchange Online users can set up an Inbox Rule either in Outlook or Outlook Web App (OWA) to filter spam/junk mail. For details of the "Spam Auto-filtering" feature please refer to FAQ "What does the Spam Auto-filtering do?" at http://www.cityu.edu.hk/csc/deptweb/support/faq/email/spamfilter/autofiltering.htm.
Following is the Inbox Rule detail:
Apply this rule after the message arrives
with X-Spam-Level: Gauge=XXXXXXXX
in the message header
move it to the Junk E-mail folder
and stop processing more rules
The above rule setting will filter email to your specified folder (e.g. the Junk E-mail folder) if the message got X-Spam-Level 80% or higher.
If you want to filter more email, say filter the email when the message got X-Spam-Level 50% or higher, simply
reduce the number of X to 5 in the rule.
i.e. To change condition with X-Spam-Level: Gauge=XXXXX in the message header
Following is the procedure of creating Inbox Rule for Spam Auto-filtering in your account with Microsoft 365 Outlook Web App (M365 OWA). You can also create similar Rule in your Microsoft 365 account using Microsoft Outlook.
