Export Powershell Object to CSV - Access Denied

I'm trying to get the permission of the calendar folder on a set user, then export it to a CSV, so we can easily view the permissions.

When I run this command:

Get-Mailbox |
    Get-MailboxPermission |
    Select-Object AccessRights, User, Identity, IsValid |
    Export-Csv -Path 'c:\Users\Connor\Desktop'

I get this error:

Export-Csv : Access to the path 'C:\Users\Connor\Desktop' is denied.
At line:1 char:89
+ ... hts,User,Identity,IsValid | Export-Csv -Path 'c:\Users\Connor\Desktop'
+                                 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : OpenError: (:) [Export-Csv], UnauthorizedAccessException

Solution

You need to make sure the PowerShell has write permission to the folder you're trying to write to. You can do this by

Relaunching Powershell as Administrator
Specifying a folder that PS can write to without elevated permissions
- Try C:\temp\ (plus your filename.csv)
- Or call Path.GetTempPath in PS with [System.IO.Path]::GetTempPath()
