EWS to DB synchronization

C# .NET, Windows services, Microsoft Exchange, Exchange Web services (EWS) and MSSQL

While all product information was in Excel, all contacts and client information was stored in an old exchange server. It’s nice and organized very well in Exchange, but those information was needed in our applications and in the Excel sheet. And that’s how the EWS to DB synchronization service came to live. That service is long died now as the Exchange server is replaced by Office365, and all client information is maintained in the database.
