Hi,
The following MS Graph APIs are working only for primary mailbox and not working for shared mailbox. Hence there is no way to set/get custom properties for emails in the shared mailbox. This is required for classifying emails as processed based on these custom properties.
" POST https://graph.microsoft.com/v1.0/users/<sharedmailbox ID>/extensions
Content-type: application/json{
"@odata.type":"microsoft.graph.openTypeExtension",
"extensionName":"<extensionName>",
"extensionProperty": <extensionProperty>
}
Content-type: application/json{
"@odata.type":"microsoft.graph.openTypeExtension",
"extensionName":"<extensionName>",
"extensionProperty": <extensionProperty>
}
GET `https://graph.microsoft.com/v1.0/users/<sharedmailbox ID>/messages/${itemId}/extensions/Microsoft.OutlookServices.OpenTypeExtension.iM.docId`;
PATCH `https://graph.microsoft.com/v1.0/users/<sharedmailbox ID>/messages/${itemId}/extensions/Microsoft.OutlookServices.OpenTypeExtension.iM.docId`;
{
"@odata.type":"microsoft.graph.openTypeExtension",
"extensionName":"<extensionName>",
"extensionProperty": <extensionProperty>
},
{
"@odata.type":"microsoft.graph.openTypeExtension",
"extensionName":"<extensionName>",
"extensionProperty": <extensionProperty>
},
DELETE `https://graph.microsoft.com/v1.0/users/<sharedmailbox ID>/messages/${itemId}/extensions/Microsoft.OutlookServices.OpenTypeExtension.iM.docId`;
{
"@odata.type":"microsoft.graph.openTypeExtension",
"extensionName":"<extensionName>",
}"
{
"@odata.type":"microsoft.graph.openTypeExtension",
"extensionName":"<extensionName>",
}"
So open extensions API (GET/POST/PATCH/DELETE) should support both primary mailbox and shared mailbox.
Thanks
Maju
