How to stop pop up when I search for contact in desktop outlook

To stop the pop-up when searching for a contact in desktop Outlook, you may need to adjust your settings related to the contact card display. If the pop-up is related to the contact card not showing user details or presence, it could be due to a policy registry key applied in your organization. You can check the following:

1. Registry Key: If the DownloadDetailsFromAD registry key is set to 0, it may prevent the display of details in the contact card. You can remove this registry key or adjust the Group Policy settings if applicable.
2. Group Policy Settings: Use the Group Policy Object Editor to manage the setting under User Configuration > Administrative Templates > Microsoft Outlook 2016 > Outlook Social Connector. Ensure the setting for downloading photos from Active Directory is set to Disabled or Not Configured.

These adjustments should help minimize or eliminate the pop-up when searching for contacts in Outlook.
