MX-Sync is an Outlook synchronization utility which synchronizes data bi-directionally (i.e. two-ways) between standard Microsoft Exchange Server Public Folders and a Microsoft SQL Server database.

It is useful in situations as described above where Outlook users are updating Public Folder information which must be constantly synchronized back to a SQL database, and/or want to use Outlook to interact with data that is stored in a SQL Server back-end ERP, accounting or web database system.

MX-Sync can be used in conjunction with MX-Contact, which is a fully comprehensive Outlook-based CRM system. However, MX-Sync does not require MX-Contact, and can synchronize to standard Exchange Server Public Folders, either discrete (i.e. non-related folders), or linked folders that form part of any Outlook-based Contact Management or CRM system.

MX-Sync can synchronize all 5 types of Outlook folders to and from a SQL Server database, namely Contact-type folders, Calendar, Task, E-Mail and Journals folders. It supports Outlook custom fields, so key ID fields that exist in the SQL tables can be synchronized to custom fields in the corresponding Outlook folders so that the relationships between the tables in SQL can also be maintained in the Outlook folders. That is, these same ID fields can be used as linking fields between the Outlook items, or used to build standard Outlook object links between items.
