Office 365 and teams work fine on Linux in Chrome or Firefox, including voice calls, video calls and screen sharing, and notifications with pop-ups and sounds.
Excel, in particular, is 100% inside Office365 in the browser when I have to interact with it. In the past, I have created Excel files in LibreOfffice and uploaded them to Office365 to convert. Though I haven’t been tempted to do so in a few years.
Most of my coworkers are not aware that I run Linux at work. My boss knows and doesn’t care. My peers are just surprised when I mention it, because I use the same tools without issue.
Zoom works great on Linux, as well, both in bowers and as the native app. Many corporate VPNs are compiant with open standards, and so don’t even require any additional install. Cisco’s isn’t made right, but they provide a Linux client that works fine.
Slack works fine in browser, including full first class notifications. I haven’t sought out a dedicated client app, but I recall having some options.
DropBox and Google have particularly decent Linux client applications, and of course, fully functional web tools.
There’s also some excellent ways to run Android apps nearly seemlessly inside an Android emulator of Linux. In theory, I could resort to those, but I haven’t because everything I need works in a web browser now.
I’ve heard that the two glaring exceptions are AutoCad and Adobe Creative Suite. I understand that neither works on Linux or in a browser (per other threads on Lemmy).
Oh yeah, and Linux has more and better ways to produce nice PDFs than Windows does, and of course reads them without issue
Oh, and yes, mandatory compliance stuff like antivirus tools and CrowdStrike also have compliant options for Linux. Some of the really shitty spyware level invasive stuff probably hasn’t been ported to Linux, but the “keep me virus free” stuff seems pretty available - because they want to sell copies for Linux servers.
Edit: If this seems needlessly thorough, it is because I worked to independently verify all of these details before my upgrade. I figure my notes might help someone making the case to switch, or just researching whether they need to not switch.

Interesting stuff. I would guess this accounts for why products with only 4 stars on Amazon are so often shit. Real consumers only seem to affect the last star out of five.
