Choosing to Connect to Microsoft Exchange Using Web Services or WebDAV
The following table indicates which options are supported by which version of Microsoft Exchange.
|Microsoft Exchange Version||Exchange (WebServices)||Exchange (WebDAV)|
|Exchange 2013 hybrid deployments (remote part)||Supported||Not supported|
|Exchange 2013||Supported||Not supported|
|Exchange 2010||Supported||Not supported|
(when the Exchange 2003 Compatibility mode is installed)
|Exchange 2003||Not supported||Supported|
You should choose the Exchange (WebDAV) option only when indexing an Exchange 2003 server. For Exchange 2007 setups, it is recommended to use the WebServices option as it offers better performances and is simpler to configure.
Note: Once a source is created, you cannot change the source type (WebDAV or WebServices). You must then create a new source using the other source type.
When you choose WebDAV, be aware that the WebDAV protocol is prohibited by default in IIS. You must therefore enable WebDAV in IIS (see Enabling WebDAV in IIS).
Configure and index the Microsoft Exchange source (see Configuring and Indexing a Microsoft Exchange Source for an On-Premises Deployment).
