I selected the Sensitivity labels in OWA and checked the value exposed in Chrome developer mode when sending an email.
When sending mail (C#-EWS sending test), i confirmed that the message was encrypted by additionally coding the header with the information below.
## Header Sample
X-MS-Exchange-Organization-ModifySensitivityLabel: 00000000-0000-0000-0000-000000000000;6e4f02ee-0f9f-44eb-9f14-57b7d505f382
msip_labels: MSIP_Label_6e4f02ee-0f9f-44eb-9f14-57b7d505f382_Enabled=True;MSIP_Label_6e4f02ee-0f9f-44eb-9f14-57b7d505f382_SiteId=a23af047-ccd4-43c4-b36d-5303e9f04b12;MSIP_Label_6e4f02ee-0f9f-44eb-9f14-57b7d505f382_SetDate=2024-03-18T00:20:34.940Z;MSIP_Label_6e4f02ee-0f9f-44eb-9f14-57b7d505f382_Name=Confidential;MSIP_Label_6e4f02ee-0f9f-44eb-9f14-57b7d505f382_ContentBits=0;MSIP_Label_6e4f02ee-0f9f-44eb-9f14-57b7d505f382_Method=Privileged;
## Question
- If only msip_labels is applied, the sensitivity label is displayed, but the message is not encrypted.
Adding X-MS-Exchange-Organization-ModifySensitivityLabel will enable message encryption. Can I code it like this?
- The msip_labels guide is provided by [concept-mip-metadata]
Where can I find the specifications for X-MS-Exchange-Organization-ModifySensitivityLabel?
- What are the limitations of development if implemented only by adding a header?
Thanks in advance
