What are three reasons aliases cannot be deleted?

Aliases cannot be deleted because they are used in an inbound workflow, associated with the users, or associated with a queue. They may also be configured as the default alias or associated with a retriever instance or mail server, but these are not reasons why they cannot be deleted.

A. If an alias is used in an inbound workflow, it cannot be deleted until it is removed from the workflow. C. If an alias is associated with a user, it cannot be deleted until it is unassigned from the user. E. If an alias is associated with a queue, it cannot be deleted until it is removed from the queue.
