I worked at a game company that was moving from google enterprise (gmail, docs, etc) to office be use our owner organization used office. Everyone fought hard to keep slack because teams is so bad. We got to keep slack but had to adopt office and it was a disaster. Outlook web and app act completely different, the mail web and app act completely different. the way to edit and share files was very confusing and always had permission issues. We were told we’d keep our email history, then the last 2 years of our history, and then finally they were unable to migrate the history and we lost years of emails. It messed the company up so much, I’m sure it’s one of the contributing factors for why the company was closed 6 months later. Like we were at the end of a 2 year development process going into soft launch, but this migration crippled production and the parent company never took responsibility.
