Unable to open PDFs from Outlook in Safari

Using the latest Safari browser, I am unable to preview password protected PDF files from outlook emails. This is not because there is a particular error, but because the dialog/field to enter passwords fails to appear in the first place.

This happens on large device screens (both Macbook and iPad) but not smaller screens (iPhones show a special pop-up to enter the password).

I have already contacted Microsoft support and they claimed "its an Apple problem". I disagree and don't exactly have much hope but I thought I would reach out on this forum to see if anyone else has an idea about how this somehow might get fixed.

Is anyone else seeing this problem? Has anyone else reported it?

A quick google check found at least two separate reports on the Microsoft community that ended with zero resolution. I don't have a lot of hope but maybe someone out there on this community can help?

Thanks in advance!
