I was at a big European company that was also somehow still on Lotus Notes in 2015, for similar reasons. Moving back to Outlook after my 5 years there was a breath of fresh air.. for a time.
I do have to say Microsoft has spent the last decade "upgrading" their product to be a similarly painful experience though.

Why Microsoft continues to burn goodwill for native Outlook to keep pushing webview "new Outlook" which isn't feature complete is beyond me. Unless we're getting webview Excel, there's no point because you won't be running Office on any other OS anyway.
