What are Microsoft Exchange Server monitoring tools?

Microsoft Exchange Server is the most widely used email, calendaring, and communication server. Its popularity arises from its ease of use, powerful applications, and clear navigation controls – mainly because of its familiar GUI – and its proven performance, robustness, and reliability.

Like all servers, Exchange also needs to be monitored and tracked to make sure it is always at optimal performance levels.

Even though its own administration and configuration dashboard can do much of the monitoring well, it can still be further enhanced – or even out-performed – by some of the best Microsoft Exchange Monitoring tools.

5. Site24x7 Microsoft Exchange Server Monitoring (FREE TRIAL)

site24x7 ms-exchange-exchange-servers

Site24x7 Microsoft Exchange Server Monitoring is part of the Website Monitoring package of tools on the Site24x7 cloud platform. The Website Monitoring service covers all manner of digital assets, not just websites. This tool is concerned with checking that all of the components of Exchange Server are contactable and performing correctly.

Key Features:

  • Backwards Compatibility: Supports versions 2007, 2007, 2010, 2013, and 2016
  • Availability Monitoring: Polls all host and client components
  • Tracks Response Times: Alerts for performance problems

Why do we recommend it?

Site24x7 Microsoft Exchange Server is part of a platform of system monitoring and management tools, so you don’t just get Exchange monitoring for your money. You also get website, server, infrastructure, Web application, and network monitoring. This represents value for money. The tool will raise an alarm if Exchange Server stops responding or runs slowly.

Exchange Server is heavily dependent on Remote Procedure Call (RPC) over HTTP. This is the mechanism that enables Outlook clients to access the Exchange Server mailboxes. So, it is a vital element in the email system and the Site24x7 monitor pays close attention to it. Response time is important and that measurement takes in the efficiency of database transactions – Exchange Server mailboxes are all held in a database.

site24x7 ms-exchange-mailbox-database

Small variations in response times don’t create problems. However, performance falls that continue to slide represent an issue that needs to be dealt with. You can also drill down to identify each stage in mail fetching, thus you will be able to see whether a slow response is due to RPC communications or database access. The monitoring service includes a series of performance expectation thresholds and a drop in RPC response will trigger one, raising an alert.

Alerts in the Site24x7 system all appear in the monitoring console. You can set up the platform so that it forwards alerts to technicians as notifications. These notifications can be sent as voice calls, SMS, emails, or Slack messages.

The package also tracks SMTP In/Out speeds. Your email system transports emails to and from your Exchange server with SMPT, which movement of mails between the server and the Outlook clients is managed by RPC. This is why those two components are the most important services to track in an Exchange Server-based system.

site24x7 ms-exchange-hub-transport

The simultaneous tracking of your entire IT system by all of the components in the Site24x7 platform provides instant root cause analysis when problems arise. All of those other monitoring modules include performance alerts, so if a problem in Exchange Server is really down to a network issue, you will already have received an alert about the network, saving you from wasting time looking into Exchange Server performance.

Who is it recommended for?

Any business that runs Exchange Server as its email system will benefit from this package. The Site24x7 platform provides much more than just email monitoring, so you get full-stack observability from the Site24x7 plans. You can’t take out a subscription to the Exchange Server Monitoring tool by itself, so make sure you can use all of the modules of Site24x7 before signing up.


  • Companion Modules Available: Exchange Server security vulnerabilities
  • Full-Stack Observability: Monitors Exchange Server performance in context
  • Performance Alerts: Notifications by email, SMS, voice call, or Slack message


  • Not a Standalone Subscription: It is bundled into system-wide monitoring plans

A number of the plans offered by Site24x7 include the Microsoft Exchange Server Monitoring unit. Take a look at the Website, Infrastructure, All-in-One, and MSP plans. The MSP edition is structured for use by managed service providers. You can get to know the entire Site24x7 platform by requesting a 30-day free trial.

Choosing a Microsoft Exchange Server monitoring tool?

The email server is perhaps one of the most important servers on a corporate network. It is the communication server that everyone relies on to deliver messages, share ideas, and collaborate on. It, therefore, makes sense to have a dedicated Microsoft Exchange monitoring tool to keep an eye on this important asset.

Among the advantages of such tools we have:

  • Ensuring the health of Exchange Servers to guarantee uninterrupted communication.
  • Making sure an Exchange Server is up and running, relaying messages to destinations, and that it is in communication with other servers in the domain.
  • Keeping on top of issues before they occur and troubleshooting them for quicker resolution.
  • Keeping and updating audits to help with reporting, troubleshooting, and tracking.
  • Informing administrators and users about stuff like policies or discrepancies in bandwidth or storage utilization to prevent bottlenecks or even total server crashes.
  • Sending – and if necessary or unanswered, escalating of – smart alerts to administrators to improve tech-support response times.
  • Checking configurations and monitoring packets and traffic to making sure an Exchange Server hasn’t been taken over by malicious code or entities for spamming and spoofing purposes, for example.

Exchange Server monitoring FAQs

How can I test my Exchange Server health?

If you have skills in PowerShell, you can use the PowerShell cmdlet Test-ServiceHealth to examine the availability of the services in Windows that are required by Exchange Server. The function will return an error status with an explanation if one of the needed services is not running.

How do I check my mailbox database status?

You can use a PowerShell cmdlet to examine the statuses of your Exchange mailbox database. This tool is called Get-MailboxDatabase and if you use it without parameters, it returns information about all databases for Exchange. You can limit that output by giving the server name as a parameter.

What is the Exchange database?

An Exchange database (EDB) is a list of the mailboxes that are available in Exchange. Each record in the database shows the user account from Active Directory that the mailbox is assigned to.
