If you are using the Exchange Managed Shell Get-MailboxFolderStatistics cmdlet to track down issues or report on folders and you want to be able to get that same folder in EWS to do something else with it here's is script that you can use to do this. This script uses the ConvertId Operation in EWS to convert the OWAId you get from EMS to a EWSId which you can then use in EWS to bind to the folder.
- ## Get the Mailbox to Access from the 1st commandline argument
- $MailboxName = $args[0]
- ## Load Managed API dll
- Add-Type -Path "C:\Program Files\Microsoft\Exchange\Web Services\1.2\Microsoft.Exchange.WebServices.dll"
- ## Set Exchange Version
- $ExchangeVersion = [Microsoft.Exchange.WebServices.Data.ExchangeVersion]::Exchange2010_SP2
- ## Create Exchange Service Object
- $service = New-Object Microsoft.Exchange.WebServices.Data.ExchangeService($ExchangeVersion)
- ## Set Credentials to use two options are availible Option1 to use explict credentials or Option 2 use the Default (logged On) credentials
- #Credentials Option 1 using UPN for the windows Account
- $psCred = Get-Credential
- $creds = New-Object System.Net.NetworkCredential($psCred.UserName.ToString(),$psCred.GetNetworkCredential().password.ToString())
- $service.Credentials = $creds
- #Credentials Option 2
- #service.UseDefaultCredentials = $true
- ## Choose to ignore any SSL Warning issues caused by Self Signed Certificates
- ## Code From http://poshcode.org/624
- ## Create a compilation environment
- $Provider=New-Object Microsoft.CSharp.CSharpCodeProvider
- $Compiler=$Provider.CreateCompiler()
- $Params=New-Object System.CodeDom.Compiler.CompilerParameters
- $Params.GenerateExecutable=$False
- $Params.GenerateInMemory=$True
- $Params.IncludeDebugInformation=$False
- $Params.ReferencedAssemblies.Add("System.DLL") | Out-Null
- $TASource=@'
- namespace Local.ToolkitExtensions.Net.CertificatePolicy{
- public class TrustAll : System.Net.ICertificatePolicy {
- public TrustAll() {
- }
- public bool CheckValidationResult(System.Net.ServicePoint sp,
- System.Security.Cryptography.X509Certificates.X509Certificate cert,
- System.Net.WebRequest req, int problem) {
- return true;
- }
- }
- }
- '@
- $TAResults=$Provider.CompileAssemblyFromSource($Params,$TASource)
- $TAAssembly=$TAResults.CompiledAssembly
- ## We now create an instance of the TrustAll and attach it to the ServicePointManager
- $TrustAll=$TAAssembly.CreateInstance("Local.ToolkitExtensions.Net.CertificatePolicy.TrustAll")
- [System.Net.ServicePointManager]::CertificatePolicy=$TrustAll
- ## end code from http://poshcode.org/624
- ## Set the URL of the CAS (Client Access Server) to use two options are availbe to use Autodiscover to find the CAS URL or Hardcode the CAS to use
- #CAS URL Option 1 Autodiscover
- $service.AutodiscoverUrl($MailboxName,{$true})
- "Using CAS Server : " + $Service.url
- #CAS URL Option 2 Hardcoded
- #$uri=[system.URI] "https://casservername/ews/exchange.asmx"
- #$service.Url = $uri
- ## Optional section for Exchange Impersonation
- #$service.ImpersonatedUserId = new-object Microsoft.Exchange.WebServices.Data.ImpersonatedUserId([Microsoft.Exchange.WebServices.Data.ConnectingIdType]::SmtpAddress, $MailboxName)
- function ConvertId{
- param (
- $OwaId = "$( throw 'OWAId is a mandatory Parameter' )"
- )
- process{
- $aiItem = New-Object Microsoft.Exchange.WebServices.Data.AlternateId
- $aiItem.Mailbox = $MailboxName
- $aiItem.UniqueId = $OwaId
- $aiItem.Format = [Microsoft.Exchange.WebServices.Data.IdFormat]::OwaId
- $convertedId = $service.ConvertId($aiItem, [Microsoft.Exchange.WebServices.Data.IdFormat]::EwsId)
- return $convertedId.UniqueId
- }
- }
- ## Get Folder id from EMS and bind to the Folder in EWS
- get-mailboxfolderstatistics $MailboxName | ForEach-Object{
- # Bind to the Inbox Folder
- $folderid= new-object Microsoft.Exchange.WebServices.Data.FolderId((Convertid $_.FolderId))
- $ewsFolder = [Microsoft.Exchange.WebServices.Data.Folder]::Bind($service,$folderid)
- $ewsFolder
- }
