Microsoft Exchange Server 2013 : Creating special-purpose mailboxes (part 8) - Creating arbitration mailboxes, Creating Discovery mailboxes

Exchange moderated transport requires all email messages sent to specific recipients to be approved by moderators. You can configure any type of recipient as a moderated recipient, and Exchange will ensure that all messages sent to those recipients go through an approval process.

Distribution groups are the only types of recipients that use moderation by default. Membership in distribution groups can be closed, owner approved, or open. While any Exchange recipient can join or leave an open distribution group, joining or leaving a closed group requires approval. Group owners receive join and remove requests and can either approve or deny those requests.

Distribution groups can also be unmoderated or moderated. With unmoderated groups, any approved sender (which is all senders by default) can send messages to the group. With moderated groups, messages are sent to moderators for approval before being distributed to members of the group. The only exception is for a message sent by a moderator. A message from a moderator is delivered immediately because a moderator has the authority to determine what is and isn’t an appropriate message.

Arbitration mailboxes are used to store messages that are awaiting approval. When you install Exchange Server 2013, a default arbitration mailbox is created. For the purposes of load balancing or for other reasons, you can convert other mailboxes to the arbitration mailbox type by using the Enable-Mailbox cmdlet. The basic syntax is as follows:

Enable-Mailbox [-Identity] Identity -Arbitration

such as:

enable-mailbox pocket-consultant.com/users/moderatedmail -Arbitration

You can create an arbitration mailbox by using New-Mailbox as shown in this example:

New-Mailbox ModeratedMail -Arbitration -UserPrincipalName
[email protected]

Exchange Discovery helps organizations comply with legal discovery requirements and can also be used as an aid in internal investigations or as part of regular monitoring of email content. Exchange Discovery uses content indexes created by Exchange Search to speed up the search process.

Whether you are working in an online, on-premises, or hybrid organization, you use Exchange Admin Center to perform searches. With hybrid configurations, an on-premises search will return results from the online organization.

Discovery searches are performed against designated mailboxes or all mailboxes in the Exchange organization. Items in mailboxes that match the Discovery search are copied to a target mailbox. Only mailboxes specifically designated as Discovery mailboxes can be used as targets. In a hybrid configuration, you must copy items to an on-premises mailbox, regardless of whether the items are from the online or on-premises organization.

In Exchange Admin Center, you can access the discovery and hold settings by selecting Compliance Management in the feature pane and then selecting In-Place eDiscovery & Hold. While working with In-Place eDiscovery & Hold, you can create searches across mailboxes by specifying filters and hold options for search results.

When you install Exchange Server 2013, a default Discovery mailbox is created. You can convert other mailboxes to the Discovery mailbox type by using the Enable-Mailbox cmdlet. The basic syntax is as follows:

Enable-Mailbox [-Identity] Identity -Discovery

such as:

enable-mailbox pocket-consultant.com/hr/legalsearch -discovery

You can create a Discovery mailbox by using New-Mailbox as shown in this example:

New-Mailbox LegalSearch -Discovery -UserPrincipalName
[email protected]

Once a Discovery mailbox is established, you can’t convert it to another mailbox type. You can’t use Exchange Admin Center to create Discovery mailboxes.
