Now we can easily search email messages by retention policy in Outlook. But this feature is not available in Outlook Web App(OWA). In this application, we demonstrate how to search email messages with retention policy enabled in Office 365 Exchange Online by using Exchange Web Service Managed API.
We use the following extend properties to search and get the information: 1. PidTagRetentionPeriod (Property ID:0x301A);2. PidTagRetentionDate (Property ID:0x301C).
You can find more code samples that demonstrate the most typical programming scenarios by using Microsoft All-In-One Code Framework Sample Browser or Sample Browser Visual Studio extension. They give you the flexibility to search samples, download samples on demand, manage the downloaded samples in a centralized place, and automatically be notified about sample updates. If it is the first time that you hear about Microsoft All-In-One Code Framework, please watch the introduction video on Microsoft Showcase, or read the introduction on our homepage http://1code.codeplex.com/.
