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 and setting up email forwarding.
IMPORTANT:DRA manages Office 365 user mailboxes as well as migrated shared, room, and equipment mailboxes. For DRA to manage these mailboxes they must be associated with an on-premise user that is managed by DRA. The mailbox properties will be available through the property pages for those associated users.
A litigation hold may be necessary when there is a reasonable expectation of a lawsuit. Organizations are required to preserve electronically stored information, including e-mail, that is relevant to the case.
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 an Exchange Online Enterprise E3 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 enable mail forwarding for user accounts via the Mail flow option in the user object’s properties.
