Question details
The user needs to restore specific contact lists that are failing to appear as address suggestions when drafting a new email.
- Product
- New Outlook for Mac
- Device & OS
- Mac
- Scenario
- Composing an email and attempting to use existing contact lists for address suggestions.
- Observed behavior
- Only three out of five contact lists populate in the address suggestion dropdown, while the other two are completely missing in version 16.94.
Ensure you have a stable internet connection and verify that your Microsoft account is actively syncing before attempting to fix your contact lists.
Verify and Recreate Contact Lists via Outlook on the Web
Use this solution to resolve synchronization glitches between the desktop application and the web server, which commonly causes specific lists to hide.
Often, missing contact lists in the desktop application are caused by a local sync issue or because the lists contain invalid contact entries. Checking the web version helps isolate the problem.
Log in to your Outlook account via a web browser and navigate to the 'People' tab to check if all five contact lists appear correctly.
Ensure that the missing lists are saved under the exact same Outlook or Microsoft account profile as the lists that are currently working.
If the lists are missing on the web or out of sync, manually recreate the two missing lists. Ensure every added contact has a valid and properly formatted email address.
Close the New Outlook for Mac completely, then reopen it to force the application to fetch the latest synchronized data from the server.
Report the Bug to Microsoft Support
If the lists are properly configured on the web but still fail to show in the Mac app, you may be experiencing a version-specific bug that requires Microsoft's intervention.

Frequently Asked Questions
Why do some contact lists work while others are missing in Outlook?
This discrepancy typically occurs if the missing lists are saved to a different account profile, contain invalid email addresses, or if a local synchronization error prevents the desktop app from fetching all lists from the server.
Did New Outlook for Mac remove mail merge features?
Yes, the New Outlook for Mac dropped traditional mail merge features that used contacts as a direct source. However, standard contact lists should still function for basic address suggestions.
How do I force Outlook for Mac to sync my contacts?
You can force a sync by completely closing and reopening the application. If the issue persists, removing and re-adding your email account under the Accounts settings usually triggers a fresh synchronization.
