O365 – How to deploy Provider Hosted App without ACS

Last week, I got an interesting requirement from the Architect to check the possibility to host the provider hosted app in the on-premise server and use the same in SharePoint Online.

To troubleshoot different issues related to certificate, the following article helped me a lot


Thank you Eric Shupps and Rainier van Slingerlandt for sharing your experience.
