Access the Shared Mailbox Directory via Outlook on the Web

Since the missing directory is a known limitation of the mobile app, using the web version allows you to securely access the shared directory.

The Outlook mobile app currently has restricted support for displaying full organization directories within shared mailboxes. By switching to the web-based client, you bypass this app limitation and can view all contacts associated with the shared account.

1
Sign in to Outlook on the web

Open a web browser and navigate to https://outlook.office.com, then sign in with your Microsoft 365 credentials.

2
Add the shared folder

Right-click on 'Folders' in the left navigation pane and select 'Add shared folder'.

3
Enter the mailbox details

Type the name or email address of the shared mailbox you want to access and click 'Add'.

4
Access the directory

Expand the newly added shared folder and navigate to the People or Contacts tab to view the organization directory.

Mobile App Limitation: If the web version correctly displays the directory, the issue stems entirely from the Outlook mobile client's design, not your account permissions.

Frequently Asked Questions

Why can I see the shared mailbox but not its contacts on my phone?

The Outlook mobile app currently restricts certain directory synchronization features for shared mailboxes. While you can send and receive emails, the organization directory linked to that shared account is often unsupported on the mobile interface.

Will removing and re-adding the shared account fix the missing directory?

In most cases, this will not resolve the issue. The missing directory is fundamentally a feature limitation of the Outlook mobile app rather than a synchronization glitch.

How can I check shared contacts on a mobile device?

The most reliable method on mobile is to open your phone's web browser, log into outlook.office.com, switch to the desktop or web view, and add the shared folder to access the directory from the People tab.
