- Product
- Microsoft Exchange Admin Center
- Device & OS
- not provided
- Scenario
- Reviewing system dashboard notifications and deciding whether old email delivery delay warnings require intervention.
- Observed behavior
- The Exchange Admin Center displays message-delay alerts from two months ago, but no newer alerts or nondelivery messages are actively appearing.
Before dismissing any system alerts, ensure you have appropriate administrative access to the Exchange Admin Center to run a message trace and verify current mail flow health.
Verify Current Mail Flow and Ignore Resolved Alerts
Investigate your recent message-tracking logs and current mail flow to confirm the issue is fully resolved before ignoring the older alerts.
System alerts in the Exchange Admin Center can occasionally linger even after a temporary network or configuration issue has been resolved. By verifying your current tracking logs, you can safely confirm that the old alerts are no longer relevant.
Log into the Exchange Admin Center and navigate to the mail flow section. Run a message trace for the past 24 to 48 hours to ensure recent messages are being successfully delivered.
Examine your current mail-flow settings and connectors to ensure there are no misconfigurations that could cause recurring bottlenecks.
Check if any new nondelivery reports (NDRs) or delay alerts have been generated in the past week. If none exist, the old alerts represent a past, temporary incident.
Once you have verified that current mail flow is healthy and there are no new alerts, you can safely ignore or dismiss the old message-delay alerts. Continue monitoring the dashboard regularly.

Frequently Asked Questions
Why do old delayed message alerts stay in the Exchange Admin Center?
Alerts may remain on the dashboard until they naturally age out or are manually dismissed by an administrator, even if the underlying mail flow issue (like a temporary network outage) was resolved shortly after it occurred.
How can I confirm my current Exchange mail flow is healthy?
You can confirm health by running a Message Trace report in the Exchange Admin Center for the last 24 to 48 hours. If messages consistently show a 'Delivered' status without errors, your mail flow is functioning properly.
What should I do if new message-delay alerts start appearing?
If new alerts appear, you should investigate immediately by checking message tracking logs, reviewing connector configurations, and inspecting your DNS records to identify what is blocking or delaying outbound or inbound mail.
