Search Emails on Exchange Server

With GemBox.Email you can search for specific messages on the Exchange Server. To search for specific emails, you can use the ExchangeClient.SearchMessages or ExchangeClient.SearchMessagesById methods.

You can do this search using the Advanced Query Syntax (AQS). You can read more about these queries on Creating a query string.

The following example shows how you can search for messages that match various criteria.
