Hello, i receiving several mails via "EmailInboundAdapter” and sending via "EmailOutboundAdapter" Now Microsoft will force OAuth 2.0 for Outlook365-Mails and want to drop POP3 basic authentication permanetly at Oct/1 2022. All have to use OAuth 2.0 then. IRIS documentation is very tiny for OAuth 2.0: https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cls?KEY=GNET\_email#GNET\_email_authentication A new paramter for a token is defined for "%Net.POP3.Connect()". But the token got only on authenication calls using ClientID and ClientSecret (last one valid for maximum 24 months). There is not support for OAuth 2.0 on EmailInboundAdapter, i think. Is it be possible to implement an own Adapter using “%Net.POP3.Connect()” with tokens? Does anyone have experiance using OAuth 2.0 for Microsoft Outlook 365? Many thanks for any hint or help!
