In the past we've been able to embed PowerPoint files stored on OneDrive for Business by creating using a process similar to this to create an embed code then putting the embed code into a Bb Item:
This used to embed PowerPoint files without any problems. However, now if students have logged into their Office 365 account then access Bb, the area where the embedded PowerPoint file should display is blank. If students are not logged into Office 365 then all is well. Office 365 has changed recently which likely has led to this issue.
Has anyone found a way to embed PowerPoint files from OneDrive for Business? I've tried a variety of methods with nothing that works consistently yet.
