I'm in the process of moving all PSTs to a central repository but need a way to reconnect them to a users outlook once moved, any help would be greatly appreciated

Here's how to attach a pst to outlook, just change the path to the pst file.

$ol = new-object -com outlook.application
$ns = $ol.getNamespace("MAPI")
$ns.AddStore("D:\outlook.pst")

Thanks

Is there anyway to do this without having to install powershell on each users machine?

You can try the same code in vbscript.

Have got the PSTs moved and reconnected via powershell perfectly thanks to your help however the only problem I have now is when the user opens outlook they still have a personal folder pointing to the old PST location as well as one pointing to the new location, is there anyway to remove the old personal folder?

IIRC $ns has a RemoveStore() method.

Hi,

There is a removestore method.  I'm having problems using it I'm using the following code:

$OL = new-object -com outlook.application
$NS = $OL.getNamespace("MAPI")
$PSTPath = "C:\Temp\Backup.Pst"
$NS.addStore($pstpath)
$PSTFolder = $NS.stores | Where {$_.FilePath -eq $PSTPath} | ?{$NS.GetFolderFromID($_.StoreID)} $NS.RemoveStore($PSTFolder)

I get this error:

Cannot convert argument "0", with value: "System.__ComObject", for "RemoveStore " to type "Microsoft.Office.Interop.Outlook.MAPIFolder": "Cannot convert the "S ystem.__ComObject" value of type "System.__ComObject#{000630c7-0000-0000-c000-0 00000000046}" to type "Microsoft.Office.Interop.Outlook.MAPIFolder"." At C:\Users\goldendel\Desktop\test.ps1:6 char:16 + $NS.RemoveStore <<<< ($PSTFolder) + CategoryInfo : NotSpecified: (:) [], MethodException + FullyQualifiedErrorId : MethodArgumentConversionInvalidCastArgument

Any clues on how I can get this working please?

Many thanks,

goldendel

I finally got this working with some help.  For anyone else looking, the RemoveStore method does not work properly via the normal powershell 2.0 methods. However, it can be done with Reflection. Here is the sample code to create a PST, backup selected folders and then disconnect the PST. The most difficult bit by far was the disconnect. It is working with Outlook 2010:
 
$outlook = New-Object -ComObject Outlook.Application $namespace = $outlook.getnamespace("MAPI")
$Calendar = $namespace.GetDefaultFolder(9)
$Contacts = $namespace.GetDefaultFolder(10)
$Tasks = $namespace.GetDefaultFolder(13)
$Notes = $namespace.GetDefaultFolder(12)
$Drafts = $namespace.GetDefaultFolder(16)
$PSTPath = "C:\Temp\Example.Pst"
$PSTDisplayName = "Backup" #Define variable for DisplayName

$namespace.AddStore($PSTPath) #Attach .PST
$PST = $namespace.Stores | ? {$_.FilePath -eq $PSTPath} #Find Store just attached as .PST
$PSTRoot = $PST.GetRootFolder() #Get Root Folder name of PST
$PSTRoot.Name = $PSTDisplayName # Change Displayname for PST to Backup

$Calendar.CopyTo($PST) | out-null #Copy Calendar items to PST
$Contacts.CopyTo($PST) | out-null #Copy Contact items to PST
$Tasks.CopyTo($PST) | out-null #Copy Task items to PST
$Notes.CopyTo($PST) | out-null #Copy Note items to PST
$Drafts.CopyTo($PST) | out-null #Copy Draft items to PST

#Cleanup Variables before PST disconnect

rm variable:Calendar
rm variable:Contacts
rm variable:Tasks
rm variable:Notes
rm variable:Drafts
$PSTFolder = $Namespace.Folders.Item($PSTDisplayName) #Bind to PST for disconnection
$Namespace.GetType().InvokeMember('RemoveStore',[System.Reflection.BindingFlags]::InvokeMethod,$null,$Namespace,($PSTFolder)) #Disconnect .PST

#Cleanup reamining variables before closure

rm variable:PSTFolder
rm variable:PSTDisplayName
rm variable:PSTRoot
rm variable:PST
rm variable:PSTPath
rm variable:namespace
rm variable:outlook

Shouldn't that be:

$Calendar.CopyTo($PST) | out-null #Copy Calendar items to PST

Instead of:

Calendar.CopyTo($PST) | out-null #Copy Calendar items to PST

?

Thanks Chris. I used the Code button, which then removed all the carraige returns when I edited it to bold the disconnect line.

I've updated $Calendar and $PSTRoot.Name
