You can configure a shared mailbox in the Outlook app, however it does not automatically add the shared mailboxes like the desktop version does. Use the following instructions to configure your shared mailbox.

  1. Navigate to settings.
  2. Click on Add Account.
  3. Click on Add Email account.
  4. Enter your e-mail address that has access to the shared mailbox. NOTE: do not enter the e-mail address of the shared mailbox.
  5. You will get redirected to office365.com. Click on Back.
  6. Choose IMAP.
  7. Enter outlook.office365.com:993.
  8. Enter your e-mail address followed by the name of the shared mailbox. For example: your e-mail address is john@company.com and the shared mailbox is info@company.com. Enter "john@company.com/info".
  9. Enter as SMTP server smtp.office365.com:587 .
  10. Enter in both fields your e-mail address and password.
  11. Save the settings. It can take a moment until Outlook shows the first e-mail messages. Even though there are e-mails in the shared mailbox, Outlook may claim temporarily that no e-mails are available in the mailbox.
