Amazon employees do :) They must be thrilled by this news.

I didn't use it, but have used Workmail, I assume it's part of the same (extremely rudimentary MS Office/Google Workspace alternative) suite. It's the kind of thing that if you use it you use it for a bit, but then the need disappears (or you move on), nobody's really using it long-term or at big scale, so nobody's really talking about it much, and AWS obviously not interested in changing that so now further limiting it or perhaps gradually killing off the whole Work* lot.

(Or actually to be fair Workmail is absolutely fine long-term and at scale if you only need the service and everyone will use whatever client. It's only really the web client that makes it look like a bit of a joke. But I'm not sure how many businesses that can really apply to, for one reason or another there's always going to be people that want/need a web client at least some of the time, or you need something else (like docs!) that anywhere you get is going to give you mail too anyway.)

I knew. Every time I accidentally didnt have "#/start" but "/start" or "/" in my personal login URL I wondered where the heck I ended up. Quite annoying. You couldn't even login there.

I genuinely wanted to. It was just too bad to be useable.

I did, it is fine. Well at least I have now 1 year to migrate.

Yes. It is awful. Good riddance.
