Remove-MgUserMailFolder not working because of invalid ID

[flourishingnixcomets]

Hello,

I've been asked to delete an Outlook folder called Promo across the whole enterprise. 

Get-MgUserMailFolder -UserId email address removed for privacy reasons -All shows all Outlook folders for me and Promo is in there.

Remove-MgUserMailFolder -MailFolderId Promo-UserId email address removed for privacy reasons returns the error 

Remove-MgUserMailFolder : Id is malformed

GET /users/email address removed for privacy reasons/mailFolders/Promo ==>I get the following error

error": {

        "code": "ErrorInvalidIdMalformed",

        "message": "Id is malformed.",

How can I remove a folder named "Promo" across the enterprise using 

Remove-MgUserMailFolder -MailFolderId Promo-UserId email address removed for privacy reasons

Many thanks,

Well you need to provide the ID of the folder, not its name. You can obtain the ID value from the first cmdlet, Get-MgUserMailFolder, it will look something like this: AAMkAGU2MWM5NzU0LWY3MmQtNGI3OS1hNDVlLTBkMzI3OWVlNWIzZgAuAAAAAAChKSJAhlnUTIHtKSso30ThAQBIPfDMxyP-RYhY8M8xmAPVAAS8XYnlAAA=

Jees I feel awkward, I have no idea how I missed the trailing =. This worked. Thank you.
