Set sensitivity label on mail message using graph api

Question

Was going through the Mail Graph API but couldnt find of any way to set the sensitivity(Private/Public/Confidential etc) on the mail message. Could you please let us know if this is feasible or not.

Answer 1

You can set it using the singleValueExtendedProperty for the PidTagSensitivity property https://learn.microsoft.com/en-us/office/client-developer/outlook/mapi/pidtagsensitivity-canonical-property eg the following sets it to personal on an email

{  
    "message": {  
        "subject": "Meet for lunch?",  
        "body": {  
            "contentType": "Text",  
            "content": "The new cafeteria is open."  
        },  
        "toRecipients": [  
            {  
                "emailAddress": {  
                    "address": "gscales@domain.com"  
                }  
            }  
        ],  
        "singleValueExtendedProperties": [  
            {  
                "id": "Integer 0x0036",  
                "value": "1"  
            }  
        ]  
    }  
}

Hi @ECIT DEV ,

Currently message sensitivity property(Public, Private, Confidential etc.) can not be set via the Graph API queries. As per documentation only these message properties can be set using Graph API.

You can submit this feature request using this support link, which will be monitored by Microsoft team and make the enhancements to Graph API.

Hope this helps.

Answer 3

@Glen Scales - Thank you for the response. I was able to set sensitivity label using extended properties.
var singleValueLegacyExtendedProperty = new SingleValueLegacyExtendedProperty
{
Id = "Integer 0x0036",
Value = "3"
};
mailmessage.SingleValueExtendedProperties = new MessageSingleValueExtendedPropertiesCollectionPage();
mailmessage.SingleValueExtendedProperties.Add(singleValueLegacyExtendedProperty);

Also is there any way i can also set DoNotForward property on mail message.

Thank you

No do not forward is part of the RMS/AIP https://learn.microsoft.com/en-us/azure/information-protection/configure-usage-rights#do-not-forward-option-for-emails which the graph doesn't support at the moment. You can disable the Forward Verb (and reply verbs (eg https://stackoverflow.com/questions/68667907/send-exchange-email-with-voting-buttons-using-ms-exchange-graph-api-java-sdk/68668010#68668010) which Outlook supports but this isn't the same as the encryption that AIP does.

Answer 5

Are you saying that can use ID's vs guids for this method - "https://<foo_domain>.sharepoint.com/_api/v2.1/drives/<driveID>/items/<docID>/setsensitivityLabel
