Outlook.com Is Quietly Rejecting Email From Domains Without DMARC

Microsoft "regrets" Outlook, Exchange, SharePoint outage after admitting it still can't fix - Neowin​

Microsoft's cloud crisis deepens as Outlook, Teams, and SharePoint remain disrupted with failed fixes, leaving customers waiting for answers.

Microsoft acknowledged the recent outage affecting several of its key services, including Outlook, Exchange Online, and SharePoint, though the more concerning part is that the company still appears to be struggling to resolve the underlying issue, after nearly half a day.

Following recent admission that the deployed fix did not work as intended, a senior exec addressed the incident expressing regret over the disruption. Charles Lamanna, Microsoft's Executive Vice President (EVP) of Business and Industry Copilot, Agents, and Platform, apologized for the disruption and acknowledged the frustration caused to customers who rely on Microsoft's cloud services for their everyday work.

Thankfully, in his post, he also confirmed that there was no indication that the incident was the result of malicious activity or a cyberattack. However, Lamanna's apology comes as Microsoft continues to struggle with restoring normal service.


As we reported yesterday, the disruption initially affected Microsoft Teams, with the company later confirming problems with Exchange Online and Outlook. Microsoft said users were experiencing difficulties accessing their mailboxes through multiple connection methods, with the incident also affecting customers in different regions.

The problem has since proved more difficult to resolve than initially expected. Microsoft's latest service updates indicate that its recovery measures have not delivered sustained results. The company says some of the changes it applied to improve service stability are not working as expected, forcing it to investigate alternative approaches to restore capacity.

The impact has extended beyond email, with certain Exchange-dependent features in Teams, SharePoint Online, Microsoft 365 Copilot, and other services also being affected. That said, Microsoft notes that accessing files stored directly in SharePoint remains functional.

At the time of writing, Microsoft is still working to restore stability, and it has yet to provide a definitive timeline for a complete recovery.

 
I don't get the issue???

Just sort your ****ing DMARC and people will get your email.

Reminds me of an issue I had to "fix".

550 5.7.509 Access denied, sending domain d00s.co.za does not pass DMARC verification and has a DMARC policy of reject.

A ****ing account manager from d00s.co.za tells me I need to fix my side, when my Exchange server checked the domain DNS TXT entry @ d00s.co.za if it should accept the email and was told to ignore.

But nooo, feeks weet beter as ek.

U.S. — National productivity skyrocketed on Thursday after Microsoft Teams went down, affording millions of Americans the rare opportunity to actually do their jobs.

Thousands of corporate meetings were canceled due to the outage, leading to an unprecedented spike in employee performance.

"It's been years since I was able to come to work and actually do my job," said local man Brian Mercer. "I've had a dozen projects piling up since last spring, which all get changed every time there's another meeting. All it took was one day without any input, and they're all done."

The remarkable burst of productivity sparked panic among middle managers, who suddenly had no reliable way to determine whether their employees were working.

"I can't see anyone's little green dot," said department supervisor Karen Whitmore. "People keep sending me finished work, but where is the dot? How can we possibly achieve synergy without the monitoring of green dots?"

Microsoft assured customers that engineers were working urgently to address the situation.

"We're aware of all the work being done during the outage," a company spokesperson said. "We understand how frustrating this is, and promise to put a stop to all that work just as soon as possible."

At publishing time, Teams had come back online, shutting down national productivity until the next Microsoft outage.
