When you switch from Classic Outlook to the new Outlook for Windows, the Global Address List often appears empty or inaccessible. This happens because the new Outlook uses a different connection method that does not automatically populate the address list from Exchange Server. You need to manually configure the directory settings to restore full access to your organization’s Global Address List. This article explains how to enable and use the Global Address List in the new Outlook after migrating from the classic version.
Key Takeaways: Accessing the Global Address List in New Outlook
- Settings > Accounts > Email > Directory Settings: Manually connect to your organization’s directory server to populate the Global Address List.
- Search bar in People module or To field: Type a name to query the Global Address List after directory settings are configured.
- File > Account Settings > Download Address Book (Classic Outlook): This option is removed in new Outlook; the directory must be set up through the new interface.
How the Global Address List Works in New Outlook
The Global Address List is a directory of all mail-enabled users, groups, and resources in your organization hosted on Exchange Server or Microsoft 365. In Classic Outlook, the GAL is automatically downloaded and cached locally when you configure an Exchange account. The new Outlook for Windows uses a modern sync engine that does not download the full GAL by default. Instead, it queries the directory in real time when you search for a recipient. If the directory connection is missing or misconfigured, the GAL appears empty or shows only cached contacts.
To use the GAL in new Outlook, you must ensure your account is correctly linked to your organization’s directory service. For Microsoft 365 accounts, this happens automatically when you sign in with your work or school account. For on-premises Exchange Server environments, you need to manually specify the directory server address. The new Outlook supports both Exchange Online and on-premises directories, but the configuration steps differ slightly.
Steps to Enable the Global Address List in New Outlook
Follow these steps to configure the directory connection and start using the Global Address List in new Outlook. These instructions apply to both Microsoft 365 and on-premises Exchange accounts.
- Open new Outlook and go to Settings
Click the gear icon in the top right corner of the new Outlook window. Select Accounts from the Settings panel that opens. - Select your email account
Under the Email section, click the account you want to use with the Global Address List. This is typically your work or school account. - Open Directory Settings
Scroll down to the Directory Settings section. If you see a button labeled Manage Directory, click it. If the section is missing, your account is already connected to Microsoft 365 and no additional setup is needed. - Enter the directory server address
In the Directory Settings dialog, enter the server address for your on-premises Exchange directory. This is usually the fully qualified domain name of your Exchange server, such asmail.example.com. Leave the port as the default 389 for LDAP or 636 for LDAP over SSL. - Test the directory connection
Click Test Connection to verify the server is reachable. If the test fails, check the server address and your network connectivity. Contact your IT administrator if the server address is unknown. - Save the settings
Click OK to save the directory settings. The new Outlook will now query the Global Address List when you search for recipients.
After completing these steps, open the People module or start composing a new email. Type a colleague’s name in the To field. The Global Address List should now appear in the search results. If names still do not appear, proceed to the next section.
If the Global Address List Still Does Not Appear
Even after configuring directory settings, you may encounter issues where the GAL remains empty or shows outdated information. The following scenarios cover the most common problems and their fixes.
Global Address List shows only my own name
This indicates the directory connection is not working. Return to Directory Settings and verify the server address. For Microsoft 365 accounts, ensure your account is listed as an Exchange Online mailbox. If you are using an on-premises server, confirm that your account has permissions to query the GAL. Your IT administrator can check the LDAP access rights on the Exchange server.
Global Address List is empty after switching from Classic Outlook
Classic Outlook downloads the GAL to a local offline address book file. The new Outlook does not use this file. If you recently switched, the new Outlook may still be syncing. Wait 15 to 30 minutes and restart the application. If the GAL remains empty, remove the account from new Outlook and add it again. Go to Settings > Accounts > Email, select the account, and choose Remove. Then add the account again using your email address. This forces a fresh directory connection.
Search returns results from personal contacts only, not the GAL
The new Outlook prioritizes local contacts over the Global Address List in search results. To see GAL results, type the full name or email address of the person. If only personal contacts appear, clear the search box and type the name again. You can also click the Directory tab in the People module to browse the GAL directly. The Directory tab is located next to the search bar when you open People.
New Outlook vs Classic Outlook: Global Address List Differences
| Item | New Outlook for Windows | Classic Outlook |
|---|---|---|
| GAL download method | Real-time LDAP queries to the directory server | Offline Address Book downloaded to local cache |
| Configuration location | Settings > Accounts > Directory Settings | File > Account Settings > Download Address Book |
| Search behavior | Returns results from GAL only when typing in To field or People search | Returns GAL results in auto-complete dropdown immediately |
| On-premises support | Requires manual LDAP server address entry | Automatic discovery via Autodiscover |
| Offline availability | No offline GAL; requires network connection | Offline GAL available after initial download |
The new Outlook trades offline GAL access for a lighter sync profile and faster startup times. If you frequently work offline and need the GAL, consider keeping Classic Outlook installed for those scenarios. Microsoft allows both versions to run side by side on the same computer.
You can now access and search the Global Address List in new Outlook after switching from Classic Outlook. For daily use, type a recipient’s name in the To field to query the GAL in real time. If you manage multiple Exchange organizations, configure separate directory settings for each account. An advanced tip: use the People module’s Directory tab to browse the GAL by department or location without typing a search query.
