Using Outlook VBA to Access AIP Labels: A Complete Guide

Outlook Scripting for AIP Label Retrieval

Email Metadata Extraction using VBA

Dim oMail As Outlook.MailItem
Dim oHeaders As Outlook.PropertyAccessor
Const PR_TRANSPORT_MESSAGE_HEADERS As String = "http://schemas.microsoft.com/mapi/proptag/0x007D001E"
Dim labelHeader As String
Dim headerValue As String

Sub RetrieveAIPLabel()
    Set oMail = Application.ActiveExplorer.Selection.Item(1)
    Set oHeaders = oMail.PropertyAccessor
    headerValue = oHeaders.GetProperty(PR_TRANSPORT_MESSAGE_HEADERS)
    labelHeader = ExtractLabel(headerValue)
    MsgBox "The AIP Label ID is: " & labelHeader
End Sub

Function ExtractLabel(headers As String) As String
    Dim startPos As Integer
    Dim endPos As Integer
    startPos = InStr(headers, "MSIP_Label_")
    If startPos > 0 Then
        headers = Mid(headers, startPos)
        endPos = InStr(headers, Chr(10)) 'Assuming line break marks the end
        ExtractLabel = Trim(Mid(headers, 1, endPos - 1))
    Else
        ExtractLabel = "No label found"
    End If
End Function

Constructing a JavaScript Label Inspection Add-In

Utilizing Office JS API to Improve Email Management

Office.onReady((info) => {
    if (info.host === Office.HostType.Outlook) {
        retrieveLabel();
    }
});

function retrieveLabel() {
    Office.context.mailbox.item.loadCustomPropertiesAsync((result) => {
        if (result.status === Office.AsyncResultStatus.Succeeded) {
            var customProps = result.value;
            var label = customProps.get("MSIP_Label");
            if (label) {
                console.log("AIP Label: " + label);
            } else {
                console.log("No AIP Label found.");
            }
        } else {
            console.error("Failed to load custom properties: " + result.error.message);
        }
    });
}
