Outlook4Gmail is an Outlook add-in providing easy contacts synchronization of your Outlook and Gmail accounts and address books.

This add-in uses the maximum correspondence of Outlook and Gmail contact details: Name, Company, Phones, Emails, Addresses, Dates, Persons, Notes, etc.

You define the direction of synchronization/update: you can sync or update either the Outlook or the Gmail address book (one-way synchronization) or choose to update both accounts simultaneously (two-way synchronization).

Outlook4Gmail Features:

Three-way synchronization of contacts will make all address books identical after the sync process is over.

Real-time synchronization/update when the Outlook address book is being changed.

Possibility to set the Gmail account list used for synchronization based on 'one-to-many,' 'many-to-one,' and 'many-to-many' schemes.

One-way synchronization of contacts when the target address book may be either in Outlook or Gmail, while the source one is declared read-only.

Synchronization of both main and additional properties of a contact (Name, Company, Phones, Emails, Addresses, Dates, Persons, Notes, etc.)

Tracking and viewing events logs of the synchronization/update process.
