MS Office (Word, Excel, Powerpoint, apps crash in AfW container

I have installed the Microsoft Office apps, like Word, Excel and PowerPoint, to the Android For Work container on my Samsung Galaxy S6. It installs fine but when launching it and trying to sign in (using my corporate account federated with O365) it crashes. I have the same apps installed outside the container and they work as expected. Anyone have a clue?

Best regards
