I'm managing a medium-sized enterprise 365 account, and we've been in complete chaos for three weeks now. Microsoft has flagged our account as suspicious, limiting each user to sending only 100 emails per day. Our outbound emails are mostly landing in spam folders, and we're having issues with incoming emails too. I reached out to Microsoft support, but their response time is slow, and they're repeating questions without providing any real help. I finally got a message from them saying they know of similar issues being reported, but it feels like no one knows what's going on. Has anyone experienced this, and how did you get it resolved?

We encountered something similar; they have a reset process but it requires all admins to have two-factor authentication enabled. If you have any old accounts that don’t meet this requirement, the reset won't work. They might not make this clear to you during support.
I've had a similar situation before. Microsoft implemented an AI to assess the risk of outgoing emails, but they laid off the team that managed it. Now, it’s left in a state where it often misjudges emails and flags accounts. When that happens, it can lead to restrictions like the ones you're facing. If you’re the only one affected, it’s frustrating because it takes longer for them to escalate the situation. They typically don’t know how to fix it besides doing a reset that only works temporarily.
How is it possible that such a crucial aspect of a giant company like Microsoft is so poorly managed? I guess it's another reason to consider using alternative systems.
So basically, I just have to wait for someone to reset it? That sounds frustrating.
There’s a good chance something flagged your account as malicious. Make sure to thoroughly check for any compromised accounts or mailboxes, even if you believe there haven’t been any breaches. It's rare for a 365 setup to be completely clear of issues like that.
I've never had to deal with that before, so how would I even know if someone compromised an account?
Sounds like your domain might have ended up on a spam blacklist. I’d suggest using tools like MX Toolbox to check your domain’s status. If it’s blacklisted, you might need to go through a delisting process.
No, we’re not sending bulk mail. It's all just normal business communications. We only send payslips monthly to employees.
Wait, so all admins need 2FA? Is there a specific 'reset' option that really helps mail flow?
