Use Cases
- Automating Mailbox Settings Retrieval for Compliance: Organizations need to track mailbox settings to ensure compliance with company policies. Automating the retrieval of mailbox settings across all users can help IT departments ensure that users are following company standards regarding automatic replies, time zones, or language settings.
