Inside Microsoft Exchange Server 2007 Web Services by David Sterling
Exchange Web Services (EWS)
EWS, which first became available in Exchange Server , provides administrators with the flexibility to store, retrieve, move and modify email and related data for a single user, a group of users or an entire Exchange Server organization on an Exchange server. EWS can be useful for migrating Exchange data on-premises or to a third-party host in the cloud., Dive deep into the architecture of Exchange Web Servicesand master the intricacies for accessing data with the new, unifying API.
Microsoft Exchange Server is a mail server and calendaring server developed by Microsoft. It runs exclusively on Windows Server operating systems. The first version was called Exchange Server 4. Exchange initially used the X. Until version 5. This was discontinued in favor of Microsoft Outlook. Exchange Server is licensed both as on-premises software and software as a service SaaS.
Exchange Server has a new feature called AutoDiscover which provides Outlook with configuration information. Internally the Exchange Server works out of the box, just using the self-signed certificate that comes in the Exchange Server installation process. Figure 1: The built-in certificate created by the Exchange Server installation process. In this scenario we will allow the internal joined workstations to be configured by the AutoDiscover service. The internal clients will receive a Certificate error pop-up when they access the OWA address, as shown in Figure Figure 2: The certificate does not have a trusted Certification Authority on the client because it was self-signed. Okay, we can avoid this kind of issue by using a certificate by a Certification Authority that is trusted by all clients.
