Hi,
I'm trying to delete some weekly meetings organized by soemone which no longer exists.
.\Update-FolderItems.ps1 -Mailbox $Mailbox -Office365 -OAuth -OAuthTenantId $tenantId -OAuthClientId $clientId -OAuthRedirectUri $redirectUrl -PropertiesMustMatch @{"0x0037001F" = "Standup Meeting It-Cloud"} -Delete -WhatIf

I have 2 errors when i want to use "Update Folder" script

20/11/2023 11:29:46 [ProcessMailbox] Unable to bind to root folder.  No further processing possible.
20/11/2023 11:29:46 [ProcessMailbox] If accessing a mailbox that has MFA enabled, you must use OAuth

I can't resolve those problems

This is usually a permissions issue (e.g. when the authenticating account does not have permission to access the specified mailbox).
