hidden contacts

The tag 'hidden contacts' on WindowsForum.com refers to contacts stored in Microsoft Outlook that are not visible in the standard address book view. Users may encounter this when exporting their Outlook address book to a CSV file, discovering many more contacts than expected. These hidden contacts can originate from various sources, such as autocomplete entries, cached addresses, or contacts from linked accounts. Discussions focus on identifying where these extra contacts come from and how to manage or remove them to align the export with the visible address book. The tag is relevant for Windows 11 and Microsoft Office 365 users troubleshooting Outlook contact management.
