Configuring Microsoft Exchange to Use a Smart Host

If a Microsoft Exchange server doesn't have a PTR record, other email servers may reject email from the Exchange server when they are unable to perform a reverse lookup on the IP address for the Exchange server. A workaround for this problem is to use a "smart host" to route outgoing email from the Exchange server.

Store.Exe Consuming Excessive Memory

On a Microsoft Exchange 2003 server, I've found Task Manager reporting high memory utilization. When I sort the running processes by memory utilization in the Task Manager (click on the Performance tab then click on the Processes column header to sort them), I see store.exe consuming over 500 MB. This is happening at the moment on a Sunday evening when few of the systems in the domain even have Outlook open to check email. The CPU utilization is low, less than 10% at the moment when I am seeing the 500 MB memory usage.

I've been seeing memory utilization jumping up to high values a lot lately. Rebooting the system resolves the problem, but I don't want to be rebooting the Exchange server every day. I can also reduce the memory utilization by selecting Run and typing services.msc to bring up the services list, I can then right-click on Microsoft Exchange Information Store and stop the service and then restart it. I then see store.exe using about 20 MB of memory when I check its utilization with the Windows Task Manager

The Microsoft Exchange Information Store service manages the Microsoft Exchange Information Store, which includes mailbox stores and public folder stores. If the service is stopped, mailbox stores and public folder stores on the computer become unavailable, so it needs to be restarted immediately after stopping it.

Determining Version of Microsoft Exchange

To determine what version of Microsoft Exchange is running on a system, you can take the following steps:
  1. Click on Start.
  2. Select All Programs.
  3. Select Microsoft Exchange.
  4. Select System Manager. Note: the System Manager is applicable if you have Exchange Server 2000 and later. For Exchange Server 5.5 and earlier, you will need to run Exchange Administrator.
  5. Click Servers. You will then see the version displayed. For Exchange Server 2000, the version is 6.0; for Exchange Server 2003, the version is 6.5.

Exchange server version

You can also determine the version number, by going to C:\Program Files\Exchsrver\bin, right-clicking on store.exe, selecting Properties, and clicking on the Version tab.

Store.exe properties

Clicking on Product version will show the version of the Exchange software. In the case shown above, the file version is listed as 6.5.7651.61 while the product version is 6.5. The digits after the 6.5 in the file version don't necessarily match the build version displayed using the first method.

Note: the version number you see using the above methods may not necessarily be the same version number you would see displayed if you telnet to port 25 on the Exchange server. E.g. the above method of determining the version of Exchange running on a system shows it to be 6.5 (Build 7638.2: Service Pack 2), but if I telnet to port 25 on that same Exchange server, I see the following:

220 Microsoft ESMTP MAIL Service, Version: 6.0.3790.3959 ready at
Wed, 13 Feb 2008 19:07:30 -0500

I.e. the "ESMTP MAIL Service" version is not the same as the version number for the Exchange server software on the system, so you can't infer that the version number you see displayed when you connect to port 25 on the system is the Exchange server version number.

Troubleshooting With the Microsoft Exchange Troubleshooting Assistant

Microsoft provides the Microsoft Exchange Troubleshooting Assistant v1.1 to aid in troubleshooting problems with Microsoft Exchange Servers. I installed and ran the tool today to try to figure out why messages sometimes get stuck in SMTP queues on an Exchange 2003 server running on a Windows Small Business Server (SBS) 2003 system.

Email Stuck in Exchange SMTP Queues

When a user complained that her email was not reaching a mailing list, I checked the Exchange server that handles her email and found messages stuck in SMTP queues on the server. I was able to force Exchange to send the queued messages, but several messages had been stuck in a queue for days with one in a queue for six days.

Enabling Microsoft Exchange Message Logging

A Microsoft Exchange user reported to me that email she sent from Outlook was not reaching recipients, but Outlook was putting it in the Sent folder indicating it had been successfully sent from Outlook.

I found that message tracking was not enabled on the Exchange server, so I needed to turn it on to try to figure out what was happening.
