Outlook StickyNote Color in Outlook on the web - exchange-server

Question

I'm developing an Outlook add-in that needs to create Outlook Notes (StickyNote). Since the Outlook REST API and Graph API don't support this I'm using Exchange Web Services (EWS). I can successfully create a note like this:
createNote(subject, body) {
var xml =
'<?xml version="1.0" encoding="utf-8"?>' +
'<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"' +
' xmlns:m="http://schemas.microsoft.com/exchange/services/2006/messages"' +
' xmlns:xsd="https://www.w3.org/2001/XMLSchema"' +
' xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"' +
' xmlns:t="http://schemas.microsoft.com/exchange/services/2006/types">' +
' <soap:Body>' +
' <m:CreateItem MessageDisposition="SaveOnly">' +
' <m:SavedItemFolderId>' +
' <t:DistinguishedFolderId Id="notes" />' +
' </m:SavedItemFolderId>' +
' <m:Items>' +
' <t:Message>' +
' <t:ItemClass>IPM.StickyNote</t:ItemClass>' +
' <t:Subject>' + subject + '</t:Subject>' +
' <t:Body>' + body + '</t:Body> ' +
' <t:ExtendedProperty>' +
' <t:ExtendedFieldURI PropertySetId="0006200E-0000-0000-C000-000000000046" PropertyId="35584" PropertyType="Integer" />' +
' <t:Value>1</t:Value>' +
' </t:ExtendedProperty>' +
' </t:Message>' +
' </m:Items>' +
' </m:CreateItem>' +
' </soap:Body>' +
'</soap:Envelope>';
Office.context.mailbox.makeEwsRequestAsync(xml, function (result) {
if (result === Office.AsyncResultStatus.Succeeded)
console.log(result.value);
});
}
The extended property is to set the color of the note (0 = blue, 1 = green, 2 = pink, 3 = yellow, 4 = white). However, this only works in the Outlook desktop app. Outlook on the web shows all the notes as gray. I assume it uses another custom property to set the color. Anyone knows how the note color can be set in Outlook on the web?

Answer 1

I would suggest you get a MAPI editor like OutlookSpy of MFCMapi and look at the following properties
If i set the color in the JSON _Note property which is a JSON string like
{"schemaVersion":"beta","documentModifiedAt":"2021-01-13T02:18:33.411Z","document":{"type":"document","blocks":[{"type":"paragraph","id":"ej73vbcb-c65a-4a4e-944a-243f540eaa16","content":[{"text":"test1","styles":null}],"blockStyles":[{"textDirection":"ltr"}]},{"type":"paragraph","id":"55pcod81-f62a-4cc8-be0b-ea28404bd60b","content":null}]},"createdWithLocalId":"1f202a39-cc90-4812-b7ff-9beef48af549","createdWithLocalId#Is.Queryable":"True","createdByApp":"OWA","createdByApp#Is.Queryable":"True","color":4,"color#Is.Queryable":"True","documentModifiedAt#Is.Queryable":"True","#type.documentModifiedAt":"DateTime","#type.createdWithLocalId":"String","#type.createdByApp":"String","#type.color":"Int32"}
and then refresh OWA that will change the color of the note in OWA. Changing the #color property doesn't seem to do anything. Some problems though this is going to be unsupported, the colors don't sync between Outlook Desktop and OWA at the moment the integers values don't event align eg 3 is Yellow in the Outlook Desktop and Pink in OWA. It maybe worth asking another question on Q&A https://learn.microsoft.com/en-us/answers/topics/office-outlook-itpro.html (don't mentioned anything about trying to use code) and just ask why the colors don't sync between the Desktop and OWA when you use the client.
