This just a couple weeks after they rolled out a dark pattern office update for Mac users to try to trick them in to 365 subscriptions.

Down

Azure communication services (ACS - transactional emails) also appears to be down. Quite amazing one thing can roll out and break so many Microsoft services at once.

Amateur hour at Microsoft. It baffles me how many companies can’t figure out how to make a status page that can handle the high loads it’ll have to sustain when the service they monitor is down. That’s pretty much the only reason to have a status page in the first place.

The M365 status page not loading reminds me of one of my favourite Simpsons jokes: https://www.youtube.com/watch?v=3Hz2uOSdV24

Yep my org as well.

It's funny how text-only niche forum that looks like it's running on RPi stuffed in someone's closet is routinely used to discuss active outages in multimillion/billion corps.

It took 30 seconds to open a "local" file in Word, and my Outlook email wasn't updating.

In other words, a day that ends in "y".

My company was recently acquired by a company that uses Office, so I'm using Microsoft products for the first time in 15 years. It's absolutely APPALLING how bad they are. I assumed they got fairly usable in the last 15 years, but it seems they've gone backwards.

For all my gripes about GSuite, ... I don't know how businesses can justify using software this bad.

> Current status: While validating the targeted change, we found that many of the affected servers have become unresponsive, which is preventing us from confirming whether the change is effective. We're restarting these servers so they can come back online with the change in place, and we're applying the same approach to additional affected portions of our infrastructure to validate the results more broadly.

I think it's safe to say, if the server is unresponsive, the change is not effective.

In the words of an ancient ...I think newgrounds(?) video embedded in a SWF, "I can't get to my email" Edit: here it is: https://www.youtube.com/watch?v=uRGljemfwUE

Hope this entertains you while we can't get to our emails.

Not sure they got the memo to host the status page in separate infrastructure...

No worries, the AI was installing an update...now it's looking for the issue, found Exchange and deleted it...

at1as • yesterday at 8:53 PM

For whatever reason 6.1 Sol is completely lobotomized for me this morning, so it wasn't helping much with the investigation, but it was pretty clear that MSFT was having issues.

I have a teams app with Outlook integration and received a bunch of 502s to smba.trafficmanager.net and a my logs are riddled with "RestError Temporary connection issue when contacting service. Please wait before retrying request"

I will say this, having apps deployed on Slack and Teams, Slack rarely has issues (an exponential backoff is enough to simply never worry about my Slack integration). With Teams I have mysterious failures to debug at least 2x a year - and they're often not very transparent about them (often my first instinct is to search Twitter and find people complaining about the same thing).

flkiwi • yesterday at 7:07 PM

Strangely, Teams chat is working fine here. Anything in Teams that is tied to other parts of O365, including the calendar, is dead. I'm currently watching a training video on sharepoint.com, so that's fine too, for now.

While I don't expect this to be the case, I'm emotionally prepared for this to be some sort of "dicks out for Harambe"-style action protesting JH's departure from Nvidia, on a larger and more technical scale.

Edit: Typo.

Remember, my guys : “Microsoft Works” is an oxymoron.

semiquaver • yesterday at 8:57 PM

My company is being pressured very aggressively by Microsoft to migrate all our users from us-managed Exchange to Microsoft-managed Exchange Online. Guess which users still have email today and which do not…

thraway2079081 • yesterday at 7:51 PM

Neither email nor Teams is working at my non-tech megacorp employer. I wonder how much of the economy this is impacting.

My employer is very very close to MSFT. Both my employer and MSFT have been aggressively moving jobs to India, and firing people in the US. It's hard not to feel some schadenfreude.

tcoff91 • yesterday at 11:00 PM

When I worked at a company that relied on this, I called it "Microsoft 361" because it went down about 4 days a year

analog31 • yesterday at 10:56 PM

On the bright side, so much work got done today.

layoric • yesterday at 11:02 PM

Also, their status page is a joke.. one entry, no timeline, is there another official one that has more detail?

mattbrewsbytes • yesterday at 7:31 PM

Did Anthropic's new release this week include an AI rollout plan (i.e. not approved by humans) to take down Office and Outlook for a lot of enterprises? I half-snarkily ask since we have seen "rogue AI" headlines before.

A fictional story about AI could be that it rolled out its new document, spreadsheet, slides, etc. apps, knows the IPO is coming up and decided to make a lot of opportunities for people to sign up for their new release by DDosing their competitor.

greatgib • today at 12:04 AM

It looks like Microsoft's legendary karma of incompetence has finally caught up with them.

who puts their status page on servers the status is supposed to be for?

Maybe due to everyone pre-downloading GTA VI today ;-)

microsucks • yesterday at 11:21 PM

We are in the middle of a SPA and DocuSign AND Hotmail (witnesses) both seem to be down. You cannot make it up.

OnceMoreUntoThe • yesterday at 6:45 PM

Sure, outlook.com is down, which is bad for everyone that chose to host their email there, I guess, but as an interesting side-effect, everyone with an on-premise Exchange server and "new Outlook" clients is affected as well.

Because, well, once upon a time there was Exchange Server and MAPI (the "Messaging API"), and that actually worked pretty well, and pretty much everyone started using it (or one of its EWS/ActiveSync offshoots), but then the Internet happened and ruined everything, but we got MAPI-over-HTTPS eventually, which by that time had grown so many warts that nobody at Microsoft really understood it anymore, so that got deprecated, even though, well, everyone and everything still uses it.

The new hotness was Azure-slash-Office-365, and that's where the "new Outlook" web interface lived and (sort-of) continues to live, and the on-prem customers got stuck with the "Exchange Subscription Edition", which was basically Exchange 2019 plus security hotfixes at extortionate rates, but with none of the new functionality.

And, since MAPI continued to be really, really hard even in the age of Copilot, access from the new hotness to the deprecated on-prem servers was implemented via IMAP (LOL), but force-proxied via the outlook.com cloud/clownshow.

Which is why, right now, many Microsoft customers that thought they were self-hosting their email are entirely down. Lessons might be learned here, but I sort-of doubt it...

Will be interesting to see if this gets attributed to AI in some way.

And magically they will claim 99.999999999999999% availability of services, when on average hyperscalers are down 1 day per year.

None of the admin ran shops are down 1 day per year.

cozzyd • yesterday at 11:22 PM

They can just rebrand as MS364

bigwheels • yesterday at 10:50 PM

They'll have to rename it Microsoft 364.

Outlook is down AND Jensen is out? it's like some cosmic convergence

Caloric3002Swed • yesterday at 7:53 PM

Office 365 parts goes down all the time. Usually around 20:00 CEST time, not sure if that is prime change time over in the USA but very handy as it is usually fixed next day.
