Quick answer
Read the intended message and review the From, To, Cc and Bcc fields before sending from Apple Mail.
Applies to
For an authorized mailbox user. Interactive Online manages settings only for mail hosted on the selected service; mail hosted elsewhere uses that provider's settings. The preserved lesson shows an earlier interface.
Steps
- Open the intended application or account and confirm its complete mailbox address and provider.
- Select the intended mailbox, open the message and use New Message, Reply or Forward as appropriate. Inspect recipients, quoted history and attachments before Send.
Check the result
Check Sent and confirm receipt with a controlled recipient. A message in Outbox has not necessarily been delivered.
Troubleshooting and support
If labels differ, use the Apple guide for the installed macOS release. For a certificate mismatch, verify the provider's secure hostname instead of accepting a guessed exception.
Contact support from the owning account with the domain, product/version, exact error, time/time zone and redacted evidence. Exclude credentials, session URLs, payment details and private customer records. Confirm any separate application-support scope.
