Capturing Powershell Errors

[swatto86]

EDIT: Apologies I just saw the post below mine to do with handling errors, I think I have the same issue because I am also in a PS-Session to set mailbox permissions.

Good Afternoon,

I have a GUI form that sets mailbox permissions in Office 365. When a mailbox does not exist I can see the powershell error in the Output pane in Powershell Studio 2015 but in my GUI application (when it is packaged) I do not get any error and my code proceeds onwards.

I have a try...catch statement around the mailbox permission command but this does not capture the raw powershell error?

Please could you explain what I am doing wrong?

Thanks,

"$_" contains the actual terminating error message within a catch block. Depending on the platform option you choose when you built the .exe (whether or not you are suppressing output), you might want to use a message box to display the error to the user.

PowerShell Code

Double-click the code block to select all.

try {
    Get-MailBox -Identity user@domain.com -ErrorAction Stop
}
catch {
    [System.Windows.Forms.MessageBox]::Show("An error occurred performing Get-MailBox. $_")
}

Alternatively, you can use the ErrorVariable parameter.

PowerShell Code

Double-click the code block to select all.

Get-MailBox -Identity user@domain.com -ErrorVariable GMBError
$GMBError

$GMBError contains the error.
