GO Contact Sync Mod is an open-source application that synchronizes contact information between Microsoft Outlook and Google Contacts, allowing users to keep their contacts in sync across both platforms. It is a free tool that is compatible with Windows, Mac, and Linux operating systems. It allows users to set up two-way synchronization, meaning that changes made to contacts on either platform will be reflected on the other platform. It also allows users to customize the synchronization process, such as which contact fields are synced, how often the synchronization will take place, and whether to delete contacts from either platform that have been deleted from the other. GO Contact Sync Mod is an excellent tool for maintaining contact information between Outlook and Google Contacts, allowing users to keep their contacts up-to-date without having to manually update both platforms.
It also synchronizes Outlook and Google but it is not free.
