I want to get tasks from an exchange server for sync in an android app. I'm not interested in contacts, emails or calendar items, just tasks.

There seems to be a few ways to connect to an exchange server but the documentation is both vast and opaque.

My server has OWA enabled but the API seems unsupported.

Any advice much appreciated.

Using the WebDAV search method you can query an Exchange store for items with content type taskfolder.

Updating items with the WebDAV protocol is accomplished either using an HTTP PUT operation for files, or by using the PROPPATCH method for items only containing properties. Since task items not necessarily are associated with files I assume you must use the PROPPATCH method to create items in the taskfolder.

Update: as of Exchange 2010, the WebDAV protocol is no longer supported. Instead, a web service API is available. Here's an example on how to get a Task item.

Clarification: the web service api was introduced in Exchange Server 2007.

To detect which Exchange version you're talking to I suggest doing a "probing" approach. Try some essential web service calls to detect 2007 and 2010, preferably using the Autodiscover operation. If these do not work, probe the WebDAV interface for earlier versions.

  • Excellent information. Thank you. Is there a WebDAV method for updating the taskfolders? – blokeley Jan 12 '11 at 08:54
  • Thanks again. Final clarification before marking this question answered: how do I detect the whether the Exchange server is 2010 or an earlier one? – blokeley Jan 13 '11 at 19:16
