Share and access another person's mailbox or folder in Outlook
You can access another person’s mailbox if you have been granted the appropriate permissions to their mailbox.
Consider these scenarios:
-
A manager needs an assistant to monitor a specific folder on his or her mailbox. In this scenario, an assistant is granted the appropriate permissions to a folder in a manager’s mailbox, but depending on the permissions granted, if they respond to a message they can only respond as themselves.
-
A manager needs an assistant to monitor email on his or her behalf. In this scenario, an assistant is granted the appropriate permissions to a manager’s folder or mailbox, but when they respond to messages, their responses are shown as coming on behalf of the manager. This type of sharing requires Delegate access permissions. For help with setting up delegate permissions, see Allow messages to be sent on your behalf when sharing a folder or mailbox.
Note: Sharing folders or mailboxes can only be done using work or school account with qualifying Microsoft 365 subscriptions, or work or school accounts hosted by Exchange Online.

Note: If the steps under this New Outlook tab don't work, you may not be using new Outlook for Windows yet. Select the Classic Outlook tab and follow those steps instead.
