What about this do you see as a negative thing? The original concept was crap, not the new change. It was ripe for spam exploitation. Having to register an actual domain, will make it more expensive for spammers, and that's a good thing.

Bullshit. You can ask for a $100 (or whatever) bond that you lose if you send spam. It's just another way to force people to go to your (even more crap) enshittified platform so you can show the market your "business model" is the greatest thing since the invention of the wheel.

I'm not sure if you understand what this story is. This is for people who have already bought a Microsoft 365 tenant but haven't assigned a real domain name to it so they're just using the default ".onmicrosoft.com" domain. No real business should do that.
This doesn't force people to any platform. The only thing it "forces" them to is to buy or use an actual domain (which they'd probably buy from a 3rd party domain registrar anyhow) if they want to send a lot of email.

Or any non-self hosted cloud in general, get what they deserve. We are using internally hosted Zimbra collaboration and Nextcloud. Screw Microshaft. We are happily saving hundreds of thousands JUST ON EMAIL ALONE.

If you have tens of thousands of users and an IT staff to manage your own hosted cloud and servers then that's great for you.
For "Joe's Landscaping" who has 13 people and outsources their IT from Geek Squad it's almost always going to be better to just use Microsoft 365 out of the box.

If your "business" is sending out emails as user@business.onmicrosoft.com instead of user@busness.com then you should take your business more seriously. Yes it saves you $20 a year for a domain registration but it also makes your emails look unprofessional and probably gets them tagged as spam. And if your company is so small that you don't feel you need a domain, then the 100 email a day limit probably won't affect you anyway.
If you take out trial and test/dev tenants, I'd be shocked if even 1% of 365 orgs are using the onmicrosoft addresses as their primary email domains. It was never meant to be used that way, it was to allow for new tenants to have a way to setup a tenant and if needed migrate emails before attaching their custom domain(s).

It's absolutely fine, though. If you're paying that $20 a month for your 1000 employees or whatever... Your money should be as good to Microsoft as anyone else's -- it should not matter whether you opt for a custom domain or their in-place domain.
What I really mean is a 100 message limit sucks for any legitimate user affected by it, And it is NOT a leg

It's really not fine though. Microsoft never meant for it to be used that way they just never enforced it because they didn't think anyone would be dumb enough to actually use it for production accounts. And I guarantee you no 1000 employee company is using the onmicrosoft as their primary email. That would be insane.
I do agree the trial tenants are the real problem, and they have put limits on them this year of 5,000 recipients a day. I think that's still too high and it should be limited to the 100 pe

I've seen many companies use a @gmail.com address. It's rather shocking how many will have a website and then email from hotmail, gmail, yahoo or other site.
If you're paying Microsoft to host your email on M365, you can probably pay for a domain.
Re: (Score:2)
Yea that's pretty unprofessional and really raises red flags about things like phishing when you get an email like that. And if have a website, you most likely already have a domain anyway. Hell I have a friend who is a professional game streamer, company of 1, and his business email uses a custom domain instead of gmail.com because it helped make him seem more professional to sponsors.

Basically the account. You buy a subscription, that gives you a Microsoft 365 account with a domain (.onmicrosoft.com by default) and you can add users and services to that. That whole account is called a "tenant".

The word ``tenant'' when spoken by the owner of a service or building/facility such as Microsoft is as a counterpart to their role as landlord, and a euphamism for the words peasant or rent-payer.

As a person paying to use their service, what's wrong with the term? Renting something doesn't make you a peasant, rich people rent things all the time.
You're just trying really, really hard to make a perfectly logical business decision (until you prove your identity, you can only send 100 emails/day) into some nefarious policy.

As I read this, when someone signs up for email service they are only able to send 100 emails/day until they verify their identity.
WTF is wrong with that?
From TFS:
> The restrictions target the onmicrosoft.com domain that Microsoft 365 automatically assigns to new tenants, limiting external messages to 100 recipients per day starting October 15.
Do customers STAY on "Microsoft.com" domain for any length of time?
> Microsoft blames spammers who exploit new tenants for quick spam bursts before detection. Affected organizations must acquire custom domains and update primary SMTP addresses across all mailboxes -- a process that requires credential updates across devices and applications.
Prove who you are, get a proper domain, send out all the emails you want... Again, I ask, WTF is wrong with that?
Do people really want to stay on the onmicrosoft.com domain for their email, or do they want their own domain?

We need a decent telecom standard such that every message and phone call is trace-able back to ISP subscriber so we can knock heads together. And high-volume senders/callers would require more identification.

However, from personal experience, Microsoft don't seem to be the biggest problem. For about half a year now, more than 95% of all phishing mails I get, across dozens of hosts, privately and on honeypots, have been coming from Google Cloud and Firebase. They don't seem interested in doing jack all about that. Google servers are on fire on blocklist, and I'm sending automated abuse reports by the boatload, but nothing ever changes.
