I am currently working on EWS to have some integration of our company application with Exchange 2010. I am using EWS to create appoinment to Exchange 2010 and it works fine; but recently I tried to add some custom/extended property when creating the appointment, below is my code to add the extended property.
The above codes able to create the custom field to the appointment.
Now here is my problem. When I open up the appointment in Outlook that I created and go to "Developer > Design This Form", then "All Fields" tab, I only see the custom field I created in the "User-defined field in folder" but not in "User-defined field in this item".
I also making an Outlook Add-in to react to the custom field that I created using the EWS when user opens up the appointment in Outlook, when I tried to look for the custom field, couldn't find the custom field, because the custom field is created in "User-defined field in folder" but not in "User-defined field in this item".
This is the codes in the Outlook Add-in and will execute when user opens an apointment in Outlook. But because the custom field is not in "in this item", the .Find() returns Nothing.
What I want to achieve is to create an appointment with the custom field (extended property) using EWS, and then read the custom field (extended property) in Outlook Add-in when user open the appointment in Outlook.
The value that i assigned to the custom field using EWS is shown in the "User-defined field in folder". How to I retrieve the value using Outlook Add-in? Maybe I can retrieve the value and add the custom field to the item?
Thanks.
Code:
Dim customField As New ExtendedPropertyDefinition(DefaultExtendedPropertySet.PublicStrings, "MyCustomField", MapiPropertyType.String)
appointment.SetExtendedProperty(customField, "CustomFieldValue")The above codes able to create the custom field to the appointment.
