Hi We are using the Microsoft.Office.Interop.Outlook.dll to create Mails from within our ERP Software and send it through the local outlook client. We are using VisualStudio2019. There are several options we are/were using (open mail window, add Address, CC, BCC, add subject and for example pdf files (like invoices or so)). With a MS Update (Customer uses Outlook Prod: MS 365 Apps for EnterpriseApps) from October/November this funcionality is not working anymore. The call from withinour Application does not find the Outlook Client anymore. Does anybod know if tht .DLL is still supported for Office2019/O365 Apps. If not is there any workarround or do we have to use the EWS Functionalty in the future. Thanks for your support. Beat Mathys
