Try/Catch -erroraction stop

PowerShell Help

Hi Guys,

 try{
    New-MailboxImportRequest -Name $UPN -BatchName $BatchName -Mailbox $UPN -AzureBlobStorageAccountUri $CompleteURI -BadItemLimit 30 -LargeItemLimit 10 -AzureSharedAccessSignatureToken $AzureToken -TargetRootFolder $AzureRootFolder -ErrorAction Stop
    } #close try
    catch
    {
    "[ERROR]`t $($_.name), something went wrong $($_.Exception.message)" | Out-File $Azureimport -Append
    } #close catch

Not sure why but when this errors the catch doesnt work. It just errors on the screen and not in the log. I realise its a non terinating error. The error in this case was:

The operation couldn't be performed because '' matches multiple entries.
    + CategoryInfo          : NotSpecified: (:) [New-MailboxImportRequest], ManagementObjectAmbiguousException
    + FullyQualifiedErrorId : [Server=MMXP123MB0655,RequestId=7fac98cc-f438-460a-8bd0-9f7717af90f5,TimeStamp=16/03/2017 05:58:39] [FailureCategory=Cmdlet-ManagementObjectAmbiguousException] A1D35C99,Microsoft.Exchange.M 
   anagement.Migration.MailboxReplication.MailboxImportRequest.NewMailboxImportRequest
    + PSComputerName        : ps.outlook.com

Any ideas welcomed

Stuart,

‘-ErrorAction Stop’ turns an error into a terminating error. See this blog post for more details.

The $Error (System.Management.Automation.ErrorRecord) does not have a ‘name’ property. You may be looking for $_.CategoryInfo.TargetName

$Azureimport = '.\Azureimport.txt'
try {
    Get-ChildItem sam -ErrorAction Stop
} catch {
    "[ERROR] '$($_.CategoryInfo.TargetName)' Something went wrong: '$($_.Exception.message)'" | 
        Out-File $Azureimport -Append
} 
notepad $Azureimport

Perfect, thank you that worked. Good article too.

Hello,

The method above worked, but if the error is different, then do I need multiple catch statements?

try{
    New-365MailboxImportRequest -Name $UPN -BatchName $BatchName -Mailbox $UPN -AzureBlobStorageAccountUri $CompleteURI -BadItemLimit 30 -LargeItemLimit 10 -AzureSharedAccessSignatureToken $AzureToken -TargetRootFolder $AzureRootFolder -ErrorAction Stop
    } #close try
    catch
    {
    "[ERROR] '$($_.CategoryInfo.TargetName)' Something went wrong: '$($_.Exception.message)'" | Out-File $Azureimport -Append

    } #close catch

Get this error:

Unable to open PST file 'https://.blob.core.windows.net/ingestiondata/hhs.stourport.sales.pst'. Error details: The remote server returned an error: (403) Forbidden.
    + CategoryInfo          : NotSpecified: (:) [New-MailboxImportRequest], RemotePermanentException
    + FullyQualifiedErrorId : [Server=MMXP12301MB1551,RequestId=491488ab-123e-4611-ac16-f8e78b68ba45,TimeStamp=05/05/2017 08:42:36] [FailureCategory=Cmdlet-RemotePermanentException] 3EC0D361,Microsoft.Exchange.Managemen 
   t.Migration.MailboxReplication.MailboxImportRequest.NewMailboxImportRequest
    + PSComputerName        : ps.outlook.com

But becasue the stop action wasnt triggered, it moves onto this line

    "[INFO]`t Mailbox $UPN has been successfully queued for import" | Out-File $Azureimport -Append

So in the log it looks like all is well, but in reality, the import failed. Any pointers on how to catch this error and any other errors that might be different?

Many THanks

In the catch block, an exception occurred and you need to decide what to do with the exception. Currently, you are only only writing a log file, but you are not terminating the execution of code. You need to use Throw or Write-Error to re-throw the error or nest the try statement:

try {
    #Splatting: https://technet.microsoft.com/en-us/library/gg675931.aspx
    $params = @{
        Name = $UPN 
        BatchName = $BatchName 
        Mailbox = $UPN 
        AzureBlobStorageAccountUri = $CompleteURI 
        BadItemLimit = 30 
        LargeItemLimit = 10 
        AzureSharedAccessSignatureToken = $AzureToken 
        TargetRootFolder = $AzureRootFolder 
        ErrorAction = "Stop"
    }
    
    
    New365MailboxImportRequest @params
} #close try
catch {
    $msg = "[ERROR] '$($_.CategoryInfo.TargetName)' Something went wrong: '$($_.Exception.message)'" 
    $msg | OutFile $Azureimport Append
    #Stop code execution
    Throw $msg
    
} #close catch

or

try {
    #Splatting: https://technet.microsoft.com/en-us/library/gg675931.aspx
    $params = @{
        Name = $UPN 
        BatchName = $BatchName 
        Mailbox = $UPN 
        AzureBlobStorageAccountUri = $CompleteURI 
        BadItemLimit = 30 
        LargeItemLimit = 10 
        AzureSharedAccessSignatureToken = $AzureToken 
        TargetRootFolder = $AzureRootFolder 
        ErrorAction = "Stop"
    }
    
    
    New365MailboxImportRequest @params

    #Only executed if previous command did not have exception
    try {
        Set-365Mailbox -Param Foo -ErrorAction Stop
    }
    catch {
        $msg = "[ERROR] '$($_.CategoryInfo.TargetName)' Next Command failed: '$($_.Exception.message)'" 
        $msg | OutFile $Azureimport Append
    }
} #close try
catch {
    $msg = "[ERROR] '$($_.CategoryInfo.TargetName)' Something went wrong: '$($_.Exception.message)'" 
    $msg | OutFile $Azureimport Append
    #Stop code execution
    #Throw $msg
    
} #close catch
