All of us knows ZoneEdit.com website, we were using it to test if the SMTP traffic is reaching our mail server or not. Now the link http://www.zoneedit.com/smtp.html is not working any more, they are providing a new services.

Don’t be sad there is another links using which you can test your mail server on port 25, here is one of them:

If you have two Network Load Balanced Exchange servers with the Hub transport and Client Access server roles installed on both of them, and you changed the NLB mode from multicast to unicast, you may not be able to send messages even if the messages are moved from the outbox folder to the Sent Item folder with the following error:

I was installing FSE SP2 on the Exchange Server. I have installed it on more than one server but on the last one, the setup hung on “Setting Up Registry” message with no errors nor warnings in the event viewer!

I found that the solution was to install Hotfix Rollup 2 for Forefront Security for Exchange Server Service Pack 1 (KB 946864).

I wrote an article about Exchange 2007 Standby Continuous Replication (SCR); an overview, how it works and how to enable it. There is also a test for SCR by moving the Exchange service to the disaster recovery (DR) site.
To read the full article, you can find it on ExchangeInbox.com @ http://www.exchangeinbox.com/article.aspx?i=149

Some times you need to increase the period for which the message tracking logs kept in your Exchange server. The default maximum age for message tracking logs in Microsoft Exchange server 2007 is 30 days:

Get-TransportServer <TransportServerName>| fl *track*

To set the maximum message tracking logs age to another period you can use the following command:

Set-TransportServer <TransportServerName> -MessageTrackingLogMaxAge dd.hh:mm:ss

Now check
Get-TransportServer <TransportServerName>| fl *track*

When you install Exchange Server in a child domain, the Outlook clients may try to communicate with the global catalog in the parent domain, this will cause a problem if the parent and the child domain is not in the same site or there is a firewall between the clients and the servers in the parent domain and cause the outlook to respond slowly.

To solve this issue you can force Outlook to communicate directly with the global catalog server in its site or with the closest catalog if the client moves between sites.
Notice that you need to edit a registry value, so make sure you take a backup of your registry before changing any value.

To force Outlook to communicate with the closest global catalog server:
-Open the Registry Editor. Click Start, click Run, type regedit.exe, and then click OK.
-Locate the following key in the registry:
HKEY_CURRENT_USER\Software\Microsoft\Exchange\Exchange Provider
You may have to create the registry path if it does not exist.
-On the Edit menu, click Add Value, and then add the following registry value:
Value name: Closest GC
Data type: REG_DWORD
Value data: 1
-Quit Registry Editor.

Or use the following command to create the key and the value:
REG ADD “HKEY_CURRENT_USER\Software\Microsoft\Exchange\Exchange Provider” /v “Closest GC” /t REG_DWORD /d 1

To force Outlook to communicate with the a specific global catalog server:
-Open the Registry Editor. Click Start, click Run, type regedit.exe, and then click OK.
-Locate the following key in the registry:
HKEY_CURRENT_USER\Software\Microsoft\Exchange\Exchange Provider
You may have to create the registry path if it does not exist.
-On the Edit menu, click Add Value, and then add the following registry value:
Value name: DS Server
Data type: REG_SZ (string)
Value data: FQDN.OF.GlobalCatalog
-Quit Registry Editor.

Or use the following command to create the key and the value:
REG ADD “HKEY_CURRENT_USER\Software\Microsoft\Exchange\Exchange Provider” /v “DS Server” /t REG_SZ /d GC.Child.Domain.Local
