Integrating K2 with Exchange Online and using OAuth Hello communityI am trying to configure K2 against Exchange Online with OAuth according to the article K2 and upcoming changes to Exchange Online authentication. I have a server in on-prem with AD only, no integration with AAD. I have tried K2 blackpearl 4.7 and K2 Five 5.5, both with the latest updates. I just want to send mails from K2 directly to Exchange Online and maybe try SmartActions. I think there are a few inaccuracies in the article, but I've gotten past some of them, but I think I have two problems near the end: 1. a simple test workflow fails to send a notification in the Task step, with a message:"Error","General","1","GeneralErrorMessage","EwsMessageDestination","1 The From Adress is empty or missing","anonymous","0.0.0.0","SRV03:C:Program Files (x86)K2 blackpearlHost ServerBin","1233361","92a69cd253b043dea89695787f260c1a","""Error","MessageBus","61007","SendMessageException","MessageBusRuntime","61007 Permanent failure sending message New Task: System.Exception: No dest
