Email queue monitoring

How long does it take an email to reach its destination mailbox? For most users, the answer would probably be inconsequential. It’s just an email after all. If not in the next second, delivery is typically complete in about a minute. But what if you're planning to run a bulk email campaign?

A typical bulk email campaign involves a significant number of messages in various email queue categories. Exchange Reporter Plus, an Exchange monitoring and reporting tool, now monitors email queues and generates reports including information on the number of queued, retrying, unreachable, and poisonous emails.

Monitor email queues to detect outages and bottlenecks

Exchange email systems have many layers and filters for spam protection. These filters could lead to latency in inbound and outbound mail flow.

Many organizations depend on email for business communication. Outages, spam emails, and slow email traffic can all be very disruptive. This is why monitoring email queues is crucial to planning the capacity of your Exchange environment and can help you know about outages before they affect the end users in your organization.
