The Message Center is a web-based console that lets users manage their quarantined messages and search for archived messages. The primary components of the Message Center are:
- Junk quarantine (On by default)
- Pending quarantine (Off by default)
- Virus quarantine (Off by default)
- Personal Archive (On by default)
- Personal settings (filters, senders lists, and language/time zone, which are all On by default).
You can control which features users can use in the Message Center, by setting their Message Center privileges. For example, you can control whether or not users can open messages in the Junk quarantine, access the Personal Archive, and manage approved and blocked senders lists.

Message Center Components
Junk quarantine
The Junk quarantine lets your users look for falsely quarantined messages and deliver them to their inboxes. This quarantine keeps messages for 14 days, and then deletes them automatically. Here’s an example of what Junk quarantine looks like in the Message Center:

Virus quarantine
The Virus quarantine lists virus-infected messages that the message security service blocked from a user's inbox. Users receive a Virus notification whenever there are messages in this quarantine. Here's what it looks like:

A few notes:
- By default, your service automatically deletes virus-infected messages, so users won't see any messages in the Virus quarantine. You can change this setting, but we recommend that you leave it as is.
- The Virus quarantine can also let users safely review the content of messages, without risking harm to their computers. However, if message archiving is turned on (it's On by default), users can't view message content, to prevent virus-infected messages from being stored in your archive.
Pending quarantine
The Pending quarantine lists messages that the message security service blocked from a user's inbox, because they may contain a new type of virus (often called "zero-hour" viruses) or other threat. Users receive an Early Detection notification whenever there are messages in this quarantine. Here's what it looks like:

A few notes:
- By default, the Pending quarantine does not appear in the Message Center. You can change this setting, but we recommend that you leave it as is.
- The Pending quarantine can also let users safely review the content of messages, without risking harm to their computers. However, if message archiving is turned on (it's On by default), users can't view message content, to prevent virus-infected messages from being stored in your archive.
Personal Archive
The Personal Archive provides users with access to their own archived messages—that is, just the messages that they sent or received. These messages are stored in your company's message archive, and they remain there for the retention period you purchased. With the Personal Archive, users can search for and recover their email messages, even if they’ve permanently deleted them from their email accounts. Here’s the Personal Archive Advanced Search panel, which helps users find the specific messages they want:
