Shared mailboxes

One address, a coordinated team

Shared mailboxes use familiar Exchange-style delegation terms, with access enforced server-side.

A shared mailbox is not a shared password.

Each delegate signs in with their own Google or Microsoft identity. Managers grant and revoke access per person.

How the mailbox behaves

Mail to a shared address is stored once and appears for every active delegate. Folder, read/unread, and star state belong to the mailbox, not the person — one shared view for the team.

  • Opening or marking a message read changes it for everyone.
  • Moving a message changes the folder for everyone with access.
  • Sent messages appear in that mailbox's Sent folder.
  • Unfinished drafts stay private to their creator; the Sent copy becomes shared after delivery.

These are cmail's own bundled access levels. “Send as” and “Full access” are familiar terms, but this is not a Microsoft Exchange server, and the permissions are not a one-to-one Exchange match.

Choose the right From identity

The From menu lists only mailboxes you can send from. Recipients see that address — never your personal sign-in identity.

  1. Open the shared mailbox or begin a new message.
  2. Choose the intended address in From.
  3. Check recipients, subject, content, and attachments.
  4. Send; the copy joins the shared Sent history.

Safe team conventions

  • Agree who triages new messages and what read/unread means for your team.
  • Use Archive or another agreed folder once work is complete.
  • Drafts are private while unfinished; use a proper case system for durable notes.
  • Ask a manager to remove access as soon as responsibilities change.
  • Use Mail trace for delivery issues; keep message content out of tickets or logs.

When an action is unavailable

A missing From address usually means Read-only access, a disabled mailbox, or a changed assignment. Disabled mailboxes stop sending and receiving until a manager re-enables them. Contact a manager rather than using another person's session.
