Manage mailbox delegation
For Exchange Online, you can use Cloud Commander to assign permissions to a mailbox or group so that other users can access the mailbox (the Full Access permission) or send email messages that appear to come from the mailbox or group (the Send as or Send on behalf permissions). In Exchange Online, the users that are assigned these permissions on other mailboxes or groups are called delegates.
In Cloud Commander users and groups are called members. You can assign members as mailbox delegates, edit member delegation roles, and unassign members from a delegated mailbox.
Assign or remove the following mailbox delegation permissions to Cloud Commander members:
- Full access: Allows the delegate to open the mailbox, and view, add and remove the contents of the mailbox. It doesn't allow the delegate to send messages from the mailbox.
- Send as: Allows the delegate to send messages as if they came directly from the mailbox. There's no indication that the message was sent by the delegate.
- Send on behalf of: Allows the delegate to send email on behalf of the mailbox. The From address of these messages clearly shows that the message was sent by the delegate.
If a user has both Send as and Send on behalf permissions for a mailbox, the Send as permission is always used.
Requirements
