Step-by-step explanation:
Interoffice memos may be addressed to all of the above. They can be addressed to an individual, several individuals, or a division or department within the organization. This flexibility allows memos to be efficiently distributed to the appropriate recipients based on the content and purpose of the memo. For example, a memo about an upcoming meeting may be addressed to the individuals who are expected to attend, while a memo about a new company policy may be addressed to a specific division or department.
