Our setup at work prevents Office from getting to the net, so all of its online features are dead. Which makes some things (e.g., changing an Image in Powerpoint) painful, since it reminds you that you're not connected. Every. single. time. you. do. it. And now they want to transition us to 365 before they fix that issue.
Not that GDrive is any better. Despite being on Windows+Office, our email system is through Google. Apparently Enterprise Drive accounts can't be opened in a browser that's logged into any non-Enterprise Drive accounts? Which means I always need to juggle multiple browsers to manage my own Drive and the work one for when the installed app won't do (and even that can only handle one account, anyway).
Which is why I now just run everything through Dropbox in direct contravention to everything the workplace wants. I'm on the verge of installing LibreOffice, too, to complete the fuck you ;)
