To restrict user activities, an administrator needs to set the permissions. Admin may have company requirements to allow some users access to another user’s mailbox. For example, you may want to allow another user to send or read email from the main user’s mailbox during their absence or send email on behalf of another user. In this case you need to set the permission based on the requirements.
You can give read/write access to a mailbox to another user using mailbox permissions or you can allow a user to read emails from the mailbox, send emails on behalf of another user, and send emails as if they were sent from that mailbox. This article will guide you to set those permissions in Office 365. These permissions can be assigned to other user mailboxes through Office 365 admin center and also in Exchange admin center.

- Read email in another users account (Read and manage)

- Send email on behalf of another user (Send on behalf)
