Exchange 2010 - Messaging Policy and Compliance

Configuring retetion tag and policy.

There are three steps involved in configuring Exchange retention tag and policy.

First we need to create retention tag using the cmdlet new-retentionpolicytag. Secondly, it has to be associated with a retention policy (new-retentionpolicy). This policy can be assigned to users using the parameter -retentionpolicy of Set-Mailbox cmdlet.

To see the results immediately you can run the cmdlet Start-ManagedFolderAssistant

Example:

[PS] C:\Windows\system32>New-RetentionPolicyTag -Name "One day retention"`
-AddressForJournaling u5@contoso.com -AgeLimitForRetention 1 -Comment`
"Retention Test" -JournalingEnabled $true -RetentionEnabled $true -RetentionAction`
movetoarchive -Type all

[PS] C:\Windows\system32>New-RetentionPolicy "Move in 1 day policy"`
-RetentionPolicyTagLinks "One day retention"

[PS] C:\Windows\system32>Set-Mailbox tariq.admin -RetentionPolicy `
"Move in 1 day policy" -Force

[PS] C:\Windows\system32>Start-ManagedFolderAssistant

-Authentication basic -Credential $credetials

Importing the session:

Import-PSSession $SessionFigure

$false -and [datetime]::now.adddays(-3) -gt $_.LastaccessTime} `
| foreach ($_) {remove-item $_.fullname -ErrorAction SilentlyContinue `
-Force}
