Use user spam notifications to release and report quarantined messages in Office 365

If your admin enables spam notifications for users, you'll receive a notification message that lists messages addressed to your mailbox that were identified as spam and quarantined instead.


If you're an administrator and want to enable this feature, you can choose the option when you modify a default anti-spam policy.

The message you receive includes the number of spam-quarantined messages you have, and the date and time (in Universal Coordinated Time or UTC) of the last message in the list. The list includes the following for each message:

  • Sender The send name and email address of the quarantined message.

  • Subject The subject line text of the quarantined message.

  • Date The date and time (in UTC) that the message was quarantined.

  • Size The size of the message, in kilobytes (KBs).

Currently, there are two actions you can take with a quarantined message:

  • Release to Inbox Choose this to send the message to your inbox, where you can view it.

  • Report as Not Junk Choose this to send a copy of the message to Microsoft for analysis. The spam team evaluates and analyzes the message, and, depending on the results of the analysis, adjusts the anti-spam filter rules to allow the message through.

Be aware of the following:

  • Messages that are quarantined because they matched a mail flow rule are not included in user quarantined messages. Only spam-quarantined messages are listed.

  • You can only release a message and report it as a false positive (not junk) once.
