You can manage quarantined emails and approve trusted senders directly from the portal. This lets you review, release, and ensure important contacts aren't blocked again. See guide: [Domain Admin](/docs/domain) How do I set up LiveArchive for email continuity during outages? LiveArchive requires no setup. Just log in when your mail server is down and continue sending and receiving emails as usual. See guide: [Deployment Guide](/docs/exchange-deployment-guide) How do I configure encryption for secure communications? Set up encryption rules through the admin portal or send encrypted messages manually. You can customize policies to protect sensitive data and meet compliance needs. See guide: [Encryption](/docs/encryption) How do I connect ExchangeDefender with my Microsoft 365 or Outlook setup? For Microsoft 365, follow the connector setup and DNS configuration steps. Outlook users can configure client-side settings for seamless integration. See guides: [M365 Setup](/docs/exchangedefender-for-m365), [Outlook / Exchange](/docs/exchange-setup), [Outlook Troubleshooting](/docs/outlook-help) How can I troubleshoot email delivery issues or configure advanced DNS settings? Check mail logs, trace delivery issues, and fine-tune DNS records like SPF, DKIM, and DMARC to ensure proper mail flow and protection. See guides: [Advanced DNS & ExchangeDefender](/docs/advanced-dns-exchangedefender), [Troubleshooting ExchangeDefender Delivery](/docs/troubleshooting-exchangedefender-delivery), [DMARC](/docs/dmarc) Still Need Help Finding Something? ---------------------------------- No worries!
