The problem was to open a PDF file from my NAS server from Synology. That occur in an error message that the file can not be open by Microsoft 365. Then I added a PDF file to one drive and try to open it with 365 in the same way as I have done it with the NAS server. (Not using the one drive function) and got the error message again. When I do that with the one drive function it works.
