You can perform a quick search for quarantined messages if a user in your organization is not receiving messages. After locating this user’s messages in the quarantine, you can view details about the messages and release them if they are false positives.
-
In the EAC, navigate to Protection > Quarantine, and then click Advanced search.
-
In the Advanced search window, select Recipient email address, type the email address of the recipient, and then click OK. You can also specify additional search conditions. For more information about these conditions, see Use the EAC to use Advanced Search to filter messages.
-
Select the message after it is displayed. (If the message is not displayed, you may want to specify a different email address for this recipient.) For information about viewing details about the message, see Use the EAC to view details about a specific quarantined message. For information about releasing the message and optionally reporting it as a false positive, see Release a Quarantined Message and Optionally Report it as a False Positive.
You can perform a targeted search for a specific message. For example, if a specific message is sent by, or intended for, a user in your organization, but it never reaches its destination, you can search for the message using the message trace feature. For details, see Run a Message Trace and View Results. If you discover that the message was sent to the quarantine, perhaps because it matched a rule or was identified as spam, you can then use advanced search to easily find the message in the quarantine using its Message ID. After locating the message in the quarantine, you can view details about the message and release the message if it is a false positive.
-
In the EAC, navigate to Protection > Quarantine, and then click Advanced search.
-
In the Advanced search window, select Message ID, specify the Message ID you are searching for, and then click OK. Be sure to include the full Message ID string. This may include angle brackets (<>).

Select the message after it is displayed. For information about viewing details about the message, see Use the EAC to view details about a specific quarantined message. For information about releasing the message and optionally reporting it as a false positive, see Release a Quarantined Message and Optionally Report it as a False Positive.
Repeat the above steps to search for additional messages.
You can filter quarantined items based on several different conditions using advanced search. You can use these conditions separately or in combination with one another. This search will provide a list of messages that meet all your filter criteria, after which you can view details about the messages and release them if they are false positives. For details, see Use the EAC to view details about a specific quarantined message and Release a Quarantined Message and Optionally Report it as a False Positive.
