Message Classifications in Exchange 2013

Posted: September 3, 2015 in Exchange

Message Classifications allow users to assign a tag to a message, such as marking it confidential.These informations Exchange Server and Outlook treat in a special fashion.When a message is classified, the message contains specific metadata that describes the intended use or audience of the message.

Classifications can be created only through EMS:

[PS] C:\Windows\system32>New-MessageClassification -Name "my classification" -DisplayName "MC" -RecipientDescription "This message may containt confidental information" -SenderDescription "Handle with care"

-RecipientDescription specifies text visible on recipient side

-SenderDescription text visible on sender side

After creating,Classifications need to be exported to xml file.Scripts folder in Exchange install directory contains script Export-OutlookClassification.ps1 which exports classifications

[PS] C:\>cd "C:\Program Files\Microsoft\Exchange Server\V15\Scripts"
[PS] C:\>C:\Program Files\Microsoft\Exchange Server\V15\Scripts>.\Export-OutlookClassification.ps1 > C:\1.xml

Classifications needs to be imported to outlook on every workstations through registry keys.

I am suprised Microsoft didn’t find more elegant way for importing classifications.

[HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Common\Policy]  office 2007
[HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Common\Policy]  office 2010
[HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Common\Policy] office 2013

AdminClassificationPath Specifies the full path and filename of the exported XML

EnableClassifications  enables (1) or disables (0) classifications

TrustClassifications  Outlook trusts classifications on messages that are sent to users on legacy Exchange Server Mailbox servers (1) or not (0)

In case you must deploy classifications on many computers (outlook 2013),i created a little batch script which can be deployed via GPO or PSExec tool

REG ADD HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\15.0\Common\Policy /f /v AdminClassificationPath /t REG_SZ /d c:\\1.xml
REG ADD HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\15.0\Common\Policy /f /v EnableClassifications /t REG_DWORD /d 00000001
REG ADD HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\15.0\Common\Policy /f /v TrustClassifications /t REG_DWORD /d 00000001

Restart outlook,compose new message-options-permission (click little “triangle” and choose classification
