Hi everybody,
I'm currently testing the new EWS Managed API.
I'd like to stamp my mails with GUID. I followed the description given in the 'Getting Started":
ExtendedPropertyDefinition extendedPropertyDefinition = new ExtendedPropertyDefinition(
yourPropertySetId,
"MyProperty",
MapiPropertyType.String);
// Stamp the extended property on a message.
message.ExtendedProperties.Add(extendedPropertyDefinition, "MyValue");
But according to the API reference the ExtendedPropertyCollection doesnot offer an Add-method. The size of the colection is always 0. Since it is a readonly property no new ExtendedPropertyCollection can be allocated.
Can anybody help me with that?
Thx in advance
Mike
