Mailbox or sending setup is still preparing
Distinguish DNS waiting from a provisioning operation that needs attention.
Editorial update: October 30, 2026In this guide
Identify the pending stage
Open mailbox or domain details and read the state. Incomplete records require DNS checks; Preparing after records pass can mean waiting for mail-service provisioning. Do not alter correct DNS just because a mailbox is not ready.
Safe next steps
- Refresh status once and check connectivity.
- For a failed operation with Retry, retry that operation rather than creating a duplicate mailbox.
- Check available storage and mailbox capacity.
- If the state does not change, record the start time, current state and operation ID if shown, then request investigation.
