What's hilarious is the home version of office was almost wholly incompatible with flagship Office... even down to the doc types.... the icing, it was called 'Microsoft Works'... a truly terrible product
Used that for damn near 15 years before I was just like “I really don’t check my email enough to even warrant having a client installed on my desktop.”
If you had told me ten years ago that I would still be using Outlook (on desktop and mobile) I would not have believed you. It’s way more stable than it was back then and honestly it’s the mail client that I find least objectionable.
