It seems like I'm suddenly unable to send or receive any emails with Microsoft 365 Exchange. Has anyone else noticed issues or is it just me?

I experienced a big delay in emails. All internal emails are fine, but external ones aren't coming through. I've even got some 'Temporary server error' messages for incoming emails. Seems to be a common issue since yesterday.
I had to double-check my DNS settings because of this. Hoping it’s sorted soon!
DownDetector is showing a really high spike in issues. I keep getting 451 errors trying to access my mail too. Seems to be widespread across the US.
I'm seeing lots of errors as well. Let's just hope they fix it soon.
It's frustrating! I had to deal with a similar issue last month.
Oh no, I just made a major change right before the outage happened! I was freaking out thinking I broke something. Thankfully it seems like it's affecting everyone, not just me.
Bad timing for sure! Who schedules this stuff?
I feel your pain! At least it's not just your changes messing things up.
Yeah, it looks like there's a widespread issue. I'm in Canada and I've seen reports that the Exchange admin dashboard isn't loading properly and we're getting 500 error codes on security.microsoft.com. It's affecting quite a few regions too!
Same here! I’m in Southern Ontario, and the dashboard isn’t working for me either.
I'm checking from the East Coast and facing the same problem. Seems like it's pretty bad.
There’s definitely something up with Microsoft 365 right now. They posted a health alert saying they're investigating issues with services, particularly Outlook. I'll keep an eye out for updates from them.
I saw that too! They said they’d update within 30 minutes, but it's been longer.
It feels like this happens way too often. Can they ever get it right?

Yep, same problems! Inbound emails are totally stalled for me.
