We solved a problem that could give a wrong constructor type error when running the Copy-Mailbox PowerShell command.

We fixed an issue where explicit managed paths could be incorrectly identified as implicit in environments other than Microsoft 365.

We fixed a Copy mailboxes issue where auto-mapping incorrectly allowed mapping between different mailbox types (e.g., user mailboxes mapped to shared mailboxes) if they had the same name, causing an error that prevented their migration.
