WebNav support for exchange2003 Tasks

Chuck · Joined: 05 Aug 2007 Posts: 2

Hello,

I am in the middle of developing a client application that is required to
syncronize Exchange2003 data with the client application's SQLserver2005
data store.

After researching the various API available to Add/Change/Delete/Retrieve
ExchangeServer2003 data remotely, I have begun to program this feature of my
application using WebNav HttpRequests and HttpResponses.

I am able to sucessfully sync exchange2003 calendar and email items, but
when I started to program exchange tasks, I found that there is apparnetly no
WebNav support for exchange2003 Tasks.?.

Can someone please give me some insite into how I can
Add/Change/Delete/Retrieve Exchange2003 tasks from a remote client
applicatoin. I would prefer to do it through the WebNav API, but if that is
not possible, then can you please let me know of any alternative API mehods
that I can use to have this functionality ?

Hi Chuck,

I assume you are using WebDAV, not WebNAV Smile

Tasks are officially only supported with Outlook Automation or Exchange 2007
WebServices. That said, you easily manipulate tasks once you know which
properties to set.

You can find some infos on http://www.cdolive.com/cdo10.htm.

If you take a look at my website (http://www.infinitec.de), you will find a
program called Mistaya there - It can help you to discover the necessary
properties. Outlook Spy is another option.

And in my WebDAV library (available with source from my website) contains a
file called WellknownProperties.cs.

It contains WebDAV property definitions for nearly the complete Outlook
Object model.

Kind regards,
Henning Krause

Hello Chuck,

I would suggest changing those

.25"

to

.25

and your namespace prefixed c should be

urn:uuid:c2f41010-65b3-11d1-a29f-00aa00c14882/

instead of

urn:schemas-microsoftcom:datatypes

Kind regards,
