Here’s an annoying error you might experience when using InfoPath Forms with Office 365 (SharePoint Online).
So to save your time, let’s go straight to the solution:
Enable Form Rendering in the Office 365 Admin Console
Go to your Office 365 Portal (http://portal.office.com) and choose Admin console.
Then Enable Form Templates Rendering for Browsers
You will see a warning about InfoPath being discontinued in the future, don’t worry about it for the moment, this is another discussion. For now, you just want to get this done.
Re-publish Your InfoPath Form Again
Now, what you have to do is to:
- Close your browser session
- Republish your InfoPath Form
Note that at the end you will see Security Level: Domain. If you see this, it means it worked. Previously you would see Security Level: Restricted.
That’s it! I hope this was helpful to you and saved you a couple of hours banging your head against the Surface keyboard
