Update

The Outlook app for iOS and Android now makes viewing shared mailboxes easy. This is a much easier way to manage mailboxes without the setup hassle.


Shared mailboxes don't have a login like your regular mailbox, so adding them to your iOS device is slightly different, but still possible, here's how.

  1. Go to Settings → Mail → Add Account
  2. Select "Other" from the list of types
  3. Select Add Mail Account
  4. Enter the fields for the mailbox
    1. Name - This is the name that appears when you send messages from this mailbox on your iOS device.
    2. Email - The email address of the shared mailbox
    3. Password - Your Office 365 password. If you have multifactor authentication enabled, use an app password.
    4. Description - Can be anything, it's how you distinguish it from other mailboxes on the phone.
  5. On the next screen select IMAP
  6. Enter the fields for the server


    1. Host Name - outlook.office365.com
    2. User Name - This should be your Office 365 email address followed by a backslash and the shared mailbox address. e.g. firstname.lastname@example.com\sharedmailbox@example.com
    3. Outgoing Mail Server - smtp.office365.com
  7. Save the settings
    1. Most likely, you'll want to switch 'Notes' off so you're just syncing email.
