  • Your Outlook contacts list might go empty or disappear due to either a technical synchronization error or a disconnected account.
  • Make sure to check your Trash or Deleted Items folder first. Your contacts might have been accidentally deleted and landed there.
  • Simply enabling or disabling your email account synchronization, or changing the connection settings of your account should restore the missing contacts.
  • Your contacts could still be present but hidden due to reconfiguration of the Outlook Address Book.

All Contacts Disappeared From Outlook? (Step-by-Step Fix)

Discovering that your complete list of contacts has been deleted in Microsoft Outlook can be quite troubling, although in most circumstances, data will not be lost forever. This is generally due to an issue with synchronization, a problem in account profile disconnection or the fact that the address book is hidden from view.

Here are a few easy methods of recovering email contacts that you may use to uncover missing contacts.

Method #1: Examine the Deleted Items Folder

  1. Launch Outlook and go to the People tab.
    Outlook People tab
  2. Find the Deleted Items Folder in your Contacts area.
  3. Right-click on the items (in case there any) and select Move > Other Folder > Contacts (dragging will work as well).
  4. Confirm if the contacts are back to your active contacts folder.

Method #2: Verify Address Book Settings in Outlook

Even though it’s possible that your contacts are still stored somewhere in your mailbox, there is still a chance that the Address Book service used by your Outlook installed program has disconnected it.

  1. Click on File > Account Settings > Account Settings…
    Select File Option
    Account Settings
    Change account settings
  2. Move to the Address Books tab and see if your primary account source is still present. In case it isn’t, you might need to add it.

  3. To check if the contacts list is available, open a new email, click on the “To” option and see if the Address Book is in the drop-down menu.

Method #3: Change Your Account Sync Space

It is common that synchronization problems between the desktop application and the e-mail server block the access to the contacts.

  1. Go to File > Account Settings > Account Settings…
    Account settings
  2. Select your email address and click Remove. It is recommended to back up or sync your emails and server data beforehand.
    Modify Email Accounts
  3. Restart the Outlook program and go to the same menu again so as to add the email address anew, thus forcing the software to download the mailbox content.
  4. Wait for a while until the process of synchronization is over and verify whether the items have downloaded successfully by opening the People tab.

Method #4: Verify Your Webmail to Determine the Cause of Crisis

To find out if the technical issue lies with your computer and its application or the server of your email:

  1. Open a browser and enter the webmail address (for example, Outlook.com or the business website of the organization).
  2. Go to the Contact Address List section of the webmail.
  3. If you see contacts in your webmail account, you can be certain that your server data is included and that the problem is in your Desktop Outlook application.
