More info: Some users email messages may send; however, users may experience delays up to one hour.
Current status: Our review of simple messages has lead us to a potential root cause where a portion of SQL infrastructure may be receiving an unusually large number of requests that may be hindering Exchange Online's performance. We're working to confirm our findings to cultivate further troubleshooting steps.

User impact: Users may encounter delays receiving external email messages in Exchange Online.
More info: Affected users may see a "451 4.7.500 Server busy" error message.
Current status: We’ve identified that specific IP addresses are being unexpectedly limited by our anti-spam procedures, causing inbound external email delivery to become throttled and delayed. We're reviewing if there have been any recent changes to our anti-spam rules to understand why the IP addresses are being limited. In the meantime, we're manually adding reported affected IP addresses to an allowed list to provide immediate relief.
Scope of impact: Impact is specific to some users who are served through the affected infrastructure.
