I'm the MD of a MS "partner". I run Arch on my gear.
LibreOffice, Draw.io (Visio), Evolution (with EWS for email) and a bit of imagination gets the job done with no MS products needed. Samba and autofs for file serving and sharing and Kerberos ("domain joined"). CUPS for printing (Kerb again).
I also have access to a huge amount of other stuff and a maximum five minute full system update time, including all apps. To be fair, if I use a few AUR packages that need compilation from source then that takes a bit longer.
