IDK about that. I have messages just vanish from my conversation history in Teams all the time. I’ll go back and try to reference something I sent somebody a month ago and parts of the conversation are just gone. I don’t have that problem with email I can pull up stuff from a decade ago if I need to.
IDK, my housemates printer required literally 0 setup to work with my linux VM and I’ve never had an issue. When I print from windows it’s a pain in the butt sometimes.
