Is Wine ever going to be able to run the current version of Microsoft Office? This is the main app keeping people in Windows.
That being said, apparently the 2016 version is gold-rated on WineHQ: https://appdb.winehq.org/objectManager.php?sClass=applicatio...
Do you have a version that doesn’t prompt users to use cloud services, and also does not attempt to make outgoing network calls?
I jumped off the MS train about ten years ago, but the office they shipped back then was already cloud encumbered.
That said, I haven't tried Office on wine in the last 2 years, and there have a lot of development in that time...
