Use Contact Lists in New Outlook After Switching From Classic Outlook

When you switch from Classic Outlook to the new Outlook for Windows, your contact lists may not appear in the same location or work the same way. In Classic Outlook, contact lists were stored in the Contacts folder and managed through the Navigation Pane. The new Outlook uses a different interface and calls these lists contact lists instead of distribution lists. This article explains where your existing contact lists are located in the new Outlook and how to create, edit, and use contact lists after switching.

The new Outlook for Windows organizes contacts differently. Your existing contact lists from Classic Outlook are still available. You just need to know where to find them and how to use them. This article covers the exact steps to locate your old contact lists, create new ones, and send email to a group of contacts in the new Outlook.

How Contact Lists Work in New Outlook vs Classic Outlook

In Classic Outlook, contact lists were called distribution lists and were stored as items in the Contacts folder. You could access them through the Navigation Pane under the Contacts module. The new Outlook for Windows replaces the Contacts folder with a People section that includes separate tabs for Contacts and Contact Lists. Contact lists in the new Outlook are syncable through your Microsoft 365 account. They appear in Outlook on the web and the Outlook mobile app as well.

The term distribution list is replaced with contact list in the new Outlook. The ability to add members, remove members, and send email to the group remains the same. The main difference is the user interface. The new Outlook does not show the classic Contacts folder in the folder pane. Instead, all contacts and contact lists are managed from the People icon on the left navigation bar.

Prerequisites for Using Contact Lists in New Outlook

To use contact lists in the new Outlook, you need a Microsoft 365 work or school account. Contact lists created in the new Outlook sync with Exchange Online. If you use a POP or IMAP account, contact lists are stored locally on your device and may not transfer automatically. You must be signed into the new Outlook with your Microsoft 365 account to see contact lists that were synced from Classic Outlook.

1. Open the People section
   Click the People icon on the left navigation bar. It looks like two silhouettes. This opens the People view where all your contacts and contact lists are stored.
2. Select the Contact Lists tab

   Double-click any contact list in the list. A window opens showing the list name and the members. You can add or remove members from this window.

Common Issues When Using Contact Lists in New Outlook

My contact lists from Classic Outlook are missing in the new Outlook

If your contact lists do not appear under the Contact Lists tab, check that you are signed into the new Outlook with the same Microsoft 365 account that you used in Classic Outlook. Contact lists created in Classic Outlook are stored in your Exchange Online mailbox. If you used a POP or IMAP account in Classic Outlook, contact lists are stored locally in a PST file. The new Outlook cannot import PST files automatically. You must import the PST file into the new Outlook using File > Open & Export > Import/Export.

The contact list name does not appear in autocomplete when composing an email

The autocomplete cache in the new Outlook may not include contact lists immediately. Type the full name of the contact list in the To field and press Enter. The list name should resolve after you send one email to it. Alternatively, click the To button and select the contact list from the Contact Lists folder manually.

I cannot add external email addresses to a contact list

Contact lists in the new Outlook only accept members that exist in your address book or your Outlook contacts. To add an external email address, first add that person as a contact in the People section. Then add that contact to the contact list.

After switching from Classic Outlook to the new Outlook, you can use contact lists by opening the People section and clicking the Contact Lists tab. Your existing distribution lists appear there automatically if you use a Microsoft 365 account. Create new contact lists using the New contact list button and add members from your address book. To send email to a contact list, type the list name in the To field or use the To button to select it from the Contact Lists folder. If you need to import contact lists from a PST file, use the Import/Export wizard in the new Outlook. For advanced management, consider creating a Microsoft 365 group instead of a contact list for features like a shared inbox and document library.
