Outlook 365 opening .msg attachment works once, then it goes to black screen at the next attachment

Hi,

I have a few users (me included) who are having a peculiar problem with Outlook 365.  When they open a mail in Outlook which contains multiple .msg's attachments, the first one opens just fine in the preview tab, but the other ones don't open. I only get a white/black screen (depending on which theme you have installed). No matter which attachment you click first, the first one you click will always open, but the rest don't.

If I then switch back to the first attachment which worked fine, that one stops working to. It only works when you double click and open them separately, but that is not a solution for the users.

What I've tried:
- All Office updates, it's up-to-date now

- Quick repair of Office
- Full reinstall of Office
- Outlook.exe /safe

- Outlook.exe/ reset views
- Resetted the view in Outlook manually
- New mail profile

- Using cache or online mode

Nothing works and I can't think of something else to do. Does anybody recognize this issue or knows what to do? I've included a screenshot of what we are getting
