Write-ErrorMessage : ||The operation couldn't be performed because 'lhau:\calendar' couldn't
be found.

Get-MailboxFolderPermission lhau:\calendarThis error can be confusing at first glance because you know the user has a Calendar folder. So why does Exchange Online PowerShell claim it doesn’t exist?
The answer is very often: folder localization.
Why Folder Localization Causes This Error
When you access folders like Inbox, Sent Items, or CalendarPowerShell uses a localized folder name behind the scenes. The default assumption is that folder names match the English names. But if the user’s mailbox was created in a different language (e.g., German, French, Spanish), the folder name will differ.
For example:
| Folder Type | English Name | German Name | French Name |
|---|---|---|---|
| Calendar | Calendar | Kalender | Calendrier |
| Inbox | Inbox | Posteingang | Boîte de réception |
| Sent Items | Sent Items | Gesendete Elemente | Éléments envoyés |
So Get-MailboxFolderPermission lhau:\calendar will fail if the actual folder name is Kalender.
How to Find the Correct Folder Path
To avoid hardcoding localized folder names, use Get-MailboxFolderStatistics to retrieve the folder structure and locate the Calendar folder by its FolderType:
Get-MailboxFolderStatistics lhau | Where-Object {$_.FolderType -eq "Calendar"} | Select Name, FolderPathThis might return something like:
Name FolderPath ---- ---------- Kalender /Kalender
Now you know the correct folder path is lhau:\Kalender. You can then run:
Get-MailboxFolderPermission "lhau:\Kalender"And voilà – it works.
