Internet explorer was discontinued on June 15, 2022.
My new notebook has instead the browser Microsoft Edge.
I do not habe MS Office, but I have Open Office (pre installed from the seller of the notebook / I was used to libreoffice and could change to it)
This is my configuration at the moment:
Thanky for quick replay.
I see that I have written in a misleading way.
With "office" files I mean text files of the business (Office), so in my case the files of OpenOffice and LibreOffice (so for example: .odt)
I get MS Office files only very rarely and convert them immediately to .odt etc.
I’m not sure if there are any viewers for Open Office. It included a viewer in the very early days but it was quickly abandoned and stopped working. Last I looked they had not fixed it or made a replacement, but I haven’t looked recently.
It’s a question better sent to the Open Office developers. If they have a viewer which works in File Explorer, it should also work in Opus.
