I am currently trying to add a custom property to an appointment in Exchange via EWS. Unfortunatley I am little stuck here.
I found examples for C# and VB but I cannot connect the dots to make it work in powershell even though I am pretty far, I think/hope.
Connecting, binding, viewing and editing existing items and their properties all works fine but I cannnot find a way to add a custom field/property to an calendar item.
Here is what I found so far (as I said no PS):
Any help is appreciated. Thanks!

The is no native way to do this via PsSH, yet, as noted, PoSH has full access to the .Net framework just like other MS Dev tools and others.
You have to take the guidance dev links, an incorporate the code / classes or create a class of your own making then use that class in your script.
See this guidance:

Point of note...

Thanks for the response. Turns out I really was close.
As I said, I had been able to create an appointment.
To add a custom property to this appointment, you have to create an ExtendedPropertyDefinition-object, which requires a GUID:
$myGUID = [GUID]"32ed071d-932e-487e-ad14-cde3272cfcc7" $myProperty = new-object Microsoft.Exchange.WebServices.Data.ExtendedPropertyDefinition(` $myGUID,` # property GUID "myProperty",` # property name [Microsoft.Exchange.WebServices.Data.MapiPropertyType]::string` # property type )
Then you can use the SetExtendedProperty-method of the existing appointment, to add an instance of the defined property to the appointment:
$appointment.SetExtendedProperty($myProperty,"This is my String")
Finally you update the appointment:
