Messages in the QuaSar for Longer Time

Messages can be kept in the quasar for longer than the policy says. Messages that have expired are not recoverable. See the Configure anti-spam policies in EOP for more information.

Can junk mail go into a quarantine state?

Junk mail can go into a Quarantine state if it is not safe to receive it. You can either move Quarantined messages to your inbox or remove them. The messages will not be accessible after two weeks.

Remarks on the Quarantine

There is no need to remove your messages from the Quarantine. The Quarantine will automatically remove a message after 30 days if you don't release it. If you look at the messages in your Quarantine location, you will not need to do anything. The messages will be deleted when they are sent.

The message ID

The globally unique identifier of the message is called the message ID. The details flyout pane shows the message ID value if you select it. The message trace can be used to find messages.

What is in exchange?

One may ask what is in exchange. Exchange server has a feature called "spam quasar" that helps reduce the risk of losing legitimate email messages by giving a temporary storage location for messages that are identified as junk. Exchange server 2010 did not change the Spam Quarantine.

Configuring the SCL Threshold in Outlook

The message will be lost if it is rejected because of a storage quota. Exchange doesn't generate NDRs for messages that are wrapped as NDRs. You need to set Outlook delegate access permission to meet your organization's needs.

You can change the Outlook profile to show the original sender, recipient, and SCL value of the message. To see the original sender in the mail, you must use the Configure Outlook feature. The value of the scl threshold is the one that will send a message to the mailbox.

You can set the threshold to a value from 0 to 9 if you think that 0 is less likely to be a nuisance. The size of the mailbox is monitored. The volume of email messages can change because of a number of factors, including a large influx of new employees, the natural trend of larger message sizes, or the threshold value on the SCL quarantine action.

The mailbox for false positives should be monitored. If your mailbox has many false positives, you should increase your threshold. View antispam stamps in Outlook can help you determine why false positives are being delivered.

After configuring the SCL threshold, periodically monitor the settings and adjust them according to your organization's needs. If too many false positives are delivered to the mailbox, raise the threshold to a larger value. Use the Exchange Management Shell to set the SCL thresholds for content filters.

Quarantine: A server for junk mail

Quarantine. Junk mail can go into a Quarantine state if it is not safe to receive it. You can either move Quarantined messages to your inbox or remove them.

The messages will not be accessible after two weeks. The Quarantine is a server where email messages that are suspected to be junk mail are temporarily stored so that they can be reviewed and retrieved if necessary. System administrators can search for messages on a user's behalf.

Quarantine Release

Quarantine release should be easy to do. It can take a while to sort out the mail. The previous structure was intended to release emails in a serialized approach but will now be replaced with a parallel form, which will help streamline the process and save your SecOps team valuable time.
