This section contains information for administering Microsoft Office 365 mailboxes in the Delegation and Configuration console via the Account and Resource Management node and in the Web Console. With the appropriate powers, you can perform various user account management tasks, such as placing litigation holds, setting up email forwarding and so on.
IMPORTANT:DRA manages Office 365 user mailboxes as well as shared, room, and equipment mailboxes. For DRA to manage these mailboxes they must be associated with an on-premises user or Azure user that is managed by DRA. The mailbox properties will be available through the property pages for those associated users.
Set a litigation hold on a mailbox to preserve all mailbox content, including deleted items and original versions of modified items. Placing a user's mailbox on litigation hold also preserves content, if it exists, in the user's archive mailbox as well. The hold can last for a specified period, or until you remove the Litigation Hold from the mailbox.
You must have the appropriate Exchange Online license to place a litigation hold. You configure the feature via the Litigation Hold tab in the user object’s properties.
You can delegate Office 365 mailbox permissions via the Mailbox delegation tab in the user object’s properties. There are three types of permissions that you can delegate, send as, send on behalf of, and full access. The types of permission that can be delegated depends upon the receiving object type.
You can view the status of the archive mailbox for a user and the archive mailbox statistics such as storage limit and warning limit. When the archive mailbox exceeds the archive warning limit, the user is notified.
You can view the amount of the total mailbox quota that has been used.
By setting delivery restrictions, you can limit the size of incoming and outgoing messages and accept or reject incoming messages for a specific user.
You can configure message forwarding options and specify maximum recipients that a user can send a message to.
You can configure more than one email address for a user mailbox and specify the primary email address. You can also assign email addresses to user accounts that do not have mailboxes.
You can specify whether to hide the email address from appearing in the address list.
You can add informational text that you want to be displayed when a mail is sent to the user.
You can assign a sharing policy, email retention policy, role assignment policy, or address book policy for the mailbox.
