I am following the https://helpx.adobe.com/coldfusion/kb/authenticate-imap-pop-smtp-connection-oauth.html page and there is a section for <cfhttp result="httpresult" url=https://login.microsoftonline.com/1aea0321-half of the code/oauth2/v2.0/token method="post"> <cfhttpparam name="grant_type" type="formfield" value="authorization_code"> <cfhttpparam name="scope" type="formfield" value=https://outlook.office365.com/EWS.AccessAsUser.All> <cfhttpparam name="code" type="formfield" value="#url.code#"> <cfhttpparam name="client_id" type="formfield" value="4e17271f-bd66-half of client id"> <cfhttpparam name="redirect_uri" type="formfield" value=https://cf-dev2.co.weld.co.us/milllevy/oauthtest.cfm> </cfhttp> It seems to need <cfhttpparam name="client_secret" type="formfield" value="tDh8Q~2X4ae_half my client secret"> it returns a token if I add that...
