@ovoao @scriptkiddie it depends on the type of company you work for. Remember that unfortunately the skills needed to run Linux desktop for a large environment are not as common as Windows sysadmin, plus only certain distros (like openSUSE) have something native to manage deploys, applying policies w and so on. This being said, work your day through the IT department, show cost savings, present easy solutions, make sure you have allies, but in the end, these kinds of things are always political, so you need to have a clear grasp of the power dynamics. It might be a supplier or a client that uses Microsoft Teams all the time, and for your company switching to Linux could mean impacting operations and reactiveness too hard. Try to understand the current blockers, they could be many (lack of knowledge of what Linux is, existing commercial relationships, lack of skills, special features only available on Microsoft 365, lack of coherent alternative vision, and many more). For each one of them find a quick win and the related person to work it through. That's hard work :)
