I am using the Office.js CustomProperties interface to store application specific data. Using the Office.js library I can succesfully read the information back in different application sessions using Office.js.

A different API process needs to read this data using the MS Graph interface. I did read Get custom property set in Outlook Add-In via Microsoft Graph but for me it does not work. I do get the message information but without any extended properties.

What is it that I am doing wrong? After putting a lot of time in this problem any help is so welcome...

Thanks in advance,

Wilco

    Are you testing on the web client or the desktop client? The desktop client does not always immediately sync custom properties to the server, which could cause this issue. – Outlook Add-ins Team - MSFT Jan 07 '19 at 19:47

    @OutlookAdd-insTeam-MSFT : I am using the online Outlook client. Using Office.js I can read the Custom properties without any problems. Using Graph from c# or the Graph Explorer does not show any extended properties. – wilcotroost Jan 09 '19 at 06:40

    Hello @OutlookAdd-insTeam-MSFT. We explored all the examples and cases but cannot solve this problem. This the Graph Call we use **https://graph.microsoft.com/v1.0/me/messages//{msgid}/?$expand=SingleValueExtendedProperties($filter=id%20eq%20'String%20{00020329-0000-0000-C000-000000000046}%20Name%20cecp-b5db42d1-a33c-4b2a-9eb8-96f406feeea9')** but it only returns the standard message properties. You can really make us happy people with some good advice! – wilcotroost May 09 '19 at 10:48
