External Mailbox Sync
Already using Google Workspace, Microsoft 365, or iCloud? Connect your existing email accounts via secure OAuth2 or IMAP/SMTP to manage all your inboxes inside GN-Apex.
“Read, star, archive, and reply to external emails directly from your GN-Apex front desk.”
Universal Mail Sync Matrix
Connect existing business or personal email accounts to pull conversations directly into your collaborative inbox without changing MX records or migrating mail servers:
Google Workspace & Gmail
One-click OAuth2 connection. Uses Google Pub/Sub push notifications for zero-delay instant message delivery.
Microsoft 365 & Outlook
Secure Microsoft Graph API integration. Synchronizes folders, sent messages, and unread flags in real time.
iCloud & Custom IMAP
Connect any standard IMAP/SMTP server with App Password authentication and encrypted credential storage.
AES-256 Encrypted Tokens
All OAuth refresh tokens and app passwords are encrypted at rest with hardware security keys.
Connecting an External Account
Go to Settings → ApexMail → Connected Accounts and click Add External Account.
Select Google, Microsoft, or Custom IMAP/SMTP.
Complete the secure OAuth login prompt or enter your server hostnames and App Password. Messages will immediately begin synchronizing in the background.
Local-First Offline Sync
When you star, archive, or mark messages as read while on an unstable connection, GN-Apex queues your actions locally and reconciles them with the upstream provider the moment connectivity restores.
