Creating a Company-Wide Contact List in Microsoft 365

How to Create a Company-Wide List of Contacts in Microsoft 365

Contact information: how important is it to your business? What happens if you can’t find a client’s email address, or a phone number is out-of-date? Delays, annoyed clients, frustration among co-workers – everything slows down. 

Microsoft 365 has the capabilities to keep everyone in your organization just a click away from the contact details they need. But where do you start, and how do you ensure it’s set up correctly to serve your needs while prioritizing security and compliance?

Our simple step-by-step guide will walk you through everything you need to know about creating, securing, and managing a company-wide contact list in Microsoft 365.

Sharing Contacts in Microsoft 365: What You Need to Know

There are two main methods to create a shared contact list in Microsoft 365: public folders and distribution lists. The one you choose depends on your organization’s specific needs, the scale of communication, and the desired level of accessibility and security. 

Understanding these prerequisites and the importance of correct configuration settings will help maintain the integrity and confidentiality of contact information. Incorrect settings can lead to unauthorized access or non-compliance with data protection regulations.

Prerequisites for Setup
  1. Microsoft 365 Admin Access: Ensure you have administrative privileges in Microsoft 365 to create and manage contact lists.

  2. Clear Objectives: Define the purpose of the contact list. Understand whether it will be used for internal communication, external outreach, or a combination of both.

  3. Data Compilation: Prepare a comprehensive list of contacts, including names, email addresses, and any other relevant information to be included in the contact list.

  4. Security and Compliance Review: Assess your organization’s data protection policies and compliance requirements to ensure the contact list adheres to these standards.

Using Public Folders to Create a Shared Contact List

This method is ideal for organizations looking for a simple way to make contacts available to all users within Outlook. Public folders can store contacts and make them accessible for everyone – but they require careful management of permissions to ensure data security.

Step 1: Access the Exchange Admin Center
  • Log into your Microsoft 365 admin account.
  • Navigate to the Exchange Admin Center via the admin portal.
Step 2: Create a Public Folder Mailbox
  • Go to the “Public Folders” section.
  • Click the “Plus” button to add a new mailbox.
  • Provide a meaningful name for your mailbox, like “CompanyContactsMailbox”.
Step 3: Create a Root Public Folder
  • Within the Public Folders area, click the “Plus” icon again to establish a new folder.
  • Name this as a generic root folder, such as “AllCompanyFolders”.
Step 4: Set Permissions for the Root Folder
  • Manage the permissions for this root folder.
  • Ensure ‘Owner’ permissions are given to administrators, allowing full control.
Step 5: Create a Shared Contacts Public Folder
  • Open Microsoft Outlook and navigate to the folders list.
  • Find the Public Folders section and locate your root public folder.
  • Right-click on the root public folder to create a new Shared Contact folder.
  • Name this folder descriptively, like “CompanyWideContacts”.
  • Adjust permissions to control who can view or edit the contacts.
Step 6: Add Contacts Folder to Outlook Favorites
  • Locate the newly created contacts public folder within Public Folders in Outlook.
  • Right-click the folder and select “Add to Favorites” for easy access.
  • This makes the Shared Contacts folder visible in the address book list when composing emails.

Using Distribution Lists to Create a Shared Contact List

These are best suited for organizations that frequently send communications to groups of people. Distribution lists allow you to send emails to multiple recipients without entering their addresses individually, streamlining communication processes.

Step 1: Log into Microsoft 365 Admin Center
  • Access the Microsoft 365 admin center with your admin credentials.
Step 2: Navigate to Distribution Lists
  • Select “Teams and groups” from the menu.
  • Click on “Active teams and groups” and then “Distribution lists”.
Step 3: Create a Distribution List
  • Choose “Add a distribution list”.
  • Fill in the list name, a brief description, and basic setup details.
  • Add owners by selecting from your user list.
Step 4: Configure Group Email Address
  • Set up a group email address for this distribution list.
  • Decide if external emails can be received by this group.
Step 5: Review and Finalize
  • Check all entered information for accuracy.
  • Click “Create group” to complete the setup.
Step 6: Add Users to the Distribution List
  • Once the list is created, add users or contacts as needed.
  • Ensure all relevant employees are included for comprehensive company-wide communication.

Security Considerations: User Access and Private Data

When implementing company-wide contact lists in Microsoft 365, whether through Public Folders or Distribution Lists, it’s crucial to address security concerns and implement stringent access controls. These measures must protect sensitive information and ensure it remains compliant with data privacy laws.

Data Privacy and Compliance

Ensure your contact lists comply with data privacy laws such as CCPA or GDPR, especially when storing personal information. Regular audits and adherence to compliance standards are essential to safeguard data privacy.

Access Permissions

Carefully manage who has the ability to view, modify, or add contacts to these lists. For Public Folders, set granular permissions, allowing only designated administrators to have ‘Owner’ rights, while employees may have ‘Reviewer’ or ‘Contributor’ roles, limiting their ability to alter the list’s contents.

In the case of Distribution Lists, control membership and ensure only authorized personnel can add or remove members. Be cautious about granting ‘Send As’ or ‘Send on Behalf’ permissions, as these could lead to unauthorized use of the distribution list for spam or phishing attacks.

External Sharing Concerns

Consider the implications of enabling external senders to email distribution lists. While this can facilitate communication with partners or clients, it also opens avenues for potential security threats. Implementing email filtering, anti-phishing policies, and configuring user email settings can mitigate these risks.

Regular Monitoring and Review

Establish a routine for reviewing and updating contact lists to remove outdated information and ensure only current employees have access. Regular monitoring for unusual activity, such as bulk changes or unauthorized access attempts, can help detect potential security breaches early.

Training and Awareness

Educate your employees about the proper use of company-wide contact lists and the importance of data security. Awareness about phishing scams, the risks of forwarding emails to external parties, and the implications of sharing sensitive information can significantly reduce security risks.

Backup and Recovery

Implement backup solutions for your contact lists to prevent data loss in case of accidental deletion or malicious attacks. Regular backups and a clear recovery plan ensure that your organization can quickly restore vital information if needed.

Regardless of the method and configurations you opt for, the key to creating a company-wide contact list in Microsoft 365 lies in meticulous planning, correct setup, and ongoing management to ensure security and compliance.
