Add another person's mailbox to the Folder Pane:

For a person to be able to open another person’s Outlook folder in their own folder hierarchy, they must be given permission to the “Outlook Today” or root folder.  Even delegates can’t do this unless they have been granted explicit permission to the Outlook Today folder. If this fails, see the "How to Share an Office 365 Mail Folder with Another Office 365 User in the Outlook Client/Outlook Web Access" article.

  1. Click the File tab in the top left of the window.
  2. Click Account Settings, and then Account Settings.
  3. Select your Office 365 account and click the Change

  4. Click the More Settings
  5. Click the Advanced tab.
  6. Under Mailboxes, 'Open these additional mailboxes:' Click on the Add button
  7. Type the person's name in the window (e.g., Jane Doe), and click the OK button
  8. Click the OK button
  9. Click the Next button
  10. Click the Finish button
  11. Restart Outlook.
