When you edit a user mailbox, a linked mailbox, or a shared mailbox, you can view or edit the following features on the Mailbox features page. For more information, see Gestion des boîtes aux lettres utilisateur.

• Sharing policy   A sharing policy controls how users in your organization can share calendar and contact information with users outside your Exchange organization. The Default Sharing Policy is assigned to mailboxes when they’re created. You can change the sharing policy that’s assigned to the user by selecting a different one from the drop-down list.

• Role assignment policy   The role assignment policy specifies the role-based access control (RBAC) roles that are assigned to the user and control which mailbox and distribution group configuration settings users can modify. You can change the role assignment policy that’s assigned to the user by selecting a different one from the drop-down list. For more information, see:

  • Présentation des stratégies d’attribution de rôle de gestion

  • Gérer les stratégies d’attribution des rôles

• Retention policy   A retention policy is a group of retention tags that are applied to the user’s mailbox. They allow you to control how long to keep items in users' mailboxes and define what action to take on items that have reached a certain age. A retention policy isn’t assigned to a mailbox when it’s created. You can assign a retention policy to the user by selecting one from the drop-down list. For more information, see Gestion des enregistrements de messagerie dans Exchange 2016

• Address book policy   This box shows the address book policy applied to the mailbox. An address book policy allows you to segment users into specific groups to provide customized views of the address book. You can apply or change the address book policy applied to the mailbox by selecting one from the drop-down list. For more information, see Stratégies de carnet d’adresses dans Exchange 2016.

• Unified Messaging   By default, this feature is disabled. When you enable Unified Messaging (UM) for a user, the user will be able to use your organization’s UM features and a default set of UM properties are applied to the user. For information about how to enable UM for a user, see Activation de la messagerie vocale pour un utilisateur.

  Notes

  A UM dial plan and a UM mailbox policy must exist before you can enable UM for a user.

• Mobile Devices   Use this section to view and change the settings for Exchange ActiveSync, which is enabled by default. Exchange ActiveSync enables access to an Exchange mailbox from a mobile device. You can disable this feature by clicking Disable Exchange ActiveSync.

• Outlook Web App   This feature is enabled by default. Outlook Web App enables access to an Exchange mailbox from a web browser. You can disable Outlook Web App for the mailbox, and add or change an Outlook Web App mailbox policy for the mailbox.

• IMAP   This feature is enabled by default. Click Disable to disable IMAP for the mailbox.

• POP3   This feature is enabled by default. Click Disable to disable POP3 for the mailbox.

• MAPI   This feature is enabled by default. MAPI enables access to an Exchange mailbox from a MAPI client such as Outlook.

• Litigation hold   This feature is disabled by default. Litigation hold preserves deleted mailbox items and records changes made to mailbox items. Deleted items and all instances of changed items are returned in a discovery search. You can place a mailbox on litigation hold by clicking Enable. If the mailbox is on litigation hold, you can remove the litigation hold by clicking Disable.

• Archiving   If an archive mailbox doesn't exist for the user, this feature is disabled. To enable an archive mailbox, click Enable. If the user has an archive mailbox, the size of the archive mailbox and usage statistics are displayed. For more information about archive mailboxes, see Archivage inaltérable dans Exchange 2016.
