Unknown Start Trace error (183) while running Exmon

Today I’ve to run ExMon on my Exchange 2010 environment. When I start Exmon.exe, the following error occured.

The most common issue is that ExMon crashed while collecting data and the Exchange trace is in progress.  Follow the below given steps to stop the Exmon trace.

1.) Make sure the ExMon.exe process isn’t running.
2.) From CMD, Query running traces
Logman query -ets
3.) Stop Exmon trace
Logman stop “Exchange Event Trace” -ets
5.) Verify trace has stopped or is no longer running
Logman query -ets

If that did not resolve the issue, check the following:
– The Disk did not run out of space. If it did, clear out the old ETL files, make space on the drive or move the install directory to a larger drive.
– Another user is running Exmon already. Ask the other user to stop tracing and exit Exmon. Then restart your Tracing and start saving the Trace files.

How to: Bulk export mailboxes to PST in Exchange 2010

Today I’ve to create a temporary solution to backup the Exchange 2010 environment. There’s one simple solution to export all the mailboxes to PST, this is not a prevered solution for a production environment, but it works 🙂 I’ve used the following powershell commando’s.

1.) New-RoleGroup “Mailbox Import Export Group” -Roles “Mailbox Import Export”
2.) Add-RoleGroupMember “Mailbox Import Export Group” -Member “Administrator”
3.) New-MailboxExportRequest -Mailbox mswi -FilePath \\SRV-EXC01\Z$\Export_PST\mswi.PST

When you want to export all the mailboxes in your Exchange environment, you can use the following powershell command.
foreach ($mbx in (Get-Mailbox)) { New-MailboxExportRequest -Mailbox $mbx -FilePath “\\win2008srv01\c$\PST\$($mbx.Alias).pst” }


Migrate mailbox from Exchange 2003 to Exchange 2010

Today I had to perform a migration from Microsoft Exchange 2003 to 2010. The new “Move Mailbox” option is replaced with the “Local Move Request“. By default there’s a maximum of two threads at one time…so when you’ve to migrate 1000 users, you’ll have to wait a long time!

You can edit the maximum of two threads within the following file; MSExchangeMailboxReplication.exe.config. This file is located in the installation directory of Microsoft Exchange. In my environment it is D:\Program Files\Microsoft\Exchange Server\V14\Bin

Change the following settings:

  • MaxActiveMovesPerTargetMDB = “2”

The default value (as of SP1, version 218.15, at least) seems to be 2. Change the 2 to a 5, or an 8, or whatever you’d like it to be.

  • MaxActiveMovesPerSourceMDB – 5, 0, 100
  • MaxActiveMovesPerTargetMDB – 5, 0, 100

Save the file, and restart the Microsoft Exchange Mailbox Replication service. Now you can perform 5 move requests at one time!! Cool… 😉

How to: Configure custom mailtips in Exchange 2010

MailTips is a new feature in 2010, which displays informational message while a user composes a message. As an administrator, you can configure custom mailtips for a mailbox, distribution group, dynamic distribution group, mail contact and mail enabled public folders.

In this example, I want the users to see the message “Please send only e-mails with ICT related problems” while they compose an email to the ICT Helpdesk. This can be done in two ways, either from Exchange Control Panel (ECP) or Shell.

Run the following shell command to set this feature.
Set-MailBox -Identity HelpdeskICT -MailTip “Please send only e-mails with ICT related problems”
