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

Managing Exchange Server 2010 - Powershell Remote Session

First time you may have to set execution policy, enable remote session and allow unencrypted traffic.

Set the Execution Policy:
Set-ExecutionPolicy RemoteSigned

Enable Remote Session:
Enable-PSRemoting

Allow Unencrypted traffic:
set-item -force WSMan:\localhost\Client\AllowUnencrypted $true

To connect to a remote Exchange Server 2010 using different credentials, you need to create credential variable in order to pass it to Exchange Server.

$credetials = get-credential

Create a session:
(Example)

[PS] WSMan:\localhost\Client>$session = New-PSSession -ConfigurationName` microsoft.exchange -ConnectionUri https://mail.contoso.com/powershell`
-Authentication basic -Credential $credetials

Importing the session:

Import-PSSession $SessionFigure

Delete files with the name starting with public which last accessed time was 3 days before.

Get-ChildItem \\fpdftp01\EXPRESS `
| Where-Object {$_.name -match "public*" -and $_.PSIsContainer -eq `
$false -and [datetime]::now.adddays(-3) -gt $_.LastaccessTime} `
| foreach ($_) {remove-item $_.fullname -ErrorAction SilentlyContinue `
-Force}

# Consolidate files in multiple folders to a single folder.

$songs= Get-ChildItem "E:\Tamil & Tamil\Ilaiyaraja - Hits Songs" -Recurse | where-object {$_.PSIsContainer -eq $false}

$songs | foreach ($_) {copy $_.fullname "E:\Tamil & Tamil\Ilaiyaraja - Hits Songs\IllaiyarajaComplete"}

Exchange Server 2010 - Database Portability

Mounting Mailbox Database on Alternate Servers - Database Portability
Database portability is a feature that enables Exchange Server 2010 mailbox database to be moved to or mounted on any other mailbox server in the same organization.
Steps:
Source database name: movedatabase
Target database name: movedatabase1

1. Make sure to commit any uncommitted transaction log files to the source database.
Dismount the source database (in our case it is movedatabase)
Command: dismount-database "movedatabase"
Command to commit transaction logs: eseutil /r Enn
Note: To determine the logfile prefix (Enn): get-mailboxdatabase "movedatabase" fl logfileprefix

2. Create a new mailbox database on the target server
Command: New-MailboxDatabase -Name "movedatabase1" -Server Exch2010 -Edbfilepath c:\mdbdata\movedatabase\movedatabase.edb -Logfilepath c:\mdbdata\movedatabase

3. Do not mount the database, just enable the database to be overwritten
Command: Set-MailboxDatabase -identity "movedatabase1" -AllowFileRestore $true

4. Move the database files manually from source server to target (.edb file, log files and Exchange Search Catalog)

5. Mount the target database (movedatabase1)
Command: Mount-Database "movedatabase1"

6. Now you must modify the user account settings point to the mailbox on the new mailbox server. Command: Get-Mailbox -database "movedatabase" where-object {$_.objectclass -NotMatch '(SystemAttendantMailbox ExOleDbSystemMailbox)'} Set-Mailbox -database "movedatabase1"

How to find startup type of a service in Powershell.

Get-Service cmdlet does not have a property to find the startup type of a service. So we need to use Get-WMIObject.
(Get-WmiObject Win32_Service -filter "Name='W32Time'").StartMode
