Our company migrated from 2010 to O365 recently.
Seems like many links and buttons broke and one of the thing I am struggling with is "Copy Slides to Presentation"
Our users post just 1 slide to this slide library and when someone selects a few of slides and click on "Copy Slides to Presentation" they automatically open up MSPowerPoint with all slides put together.
On our O365, no pop-ups show up and it just Refreshes page (does nothing).
What could be a solution or workaround in this case?
