Send a mail and what is checked first
When you tap Send, the app checks that recipients are valid, the attachments are within the limit and ready, and warns about a missing attachment or empty subject. It may flag an address that does not exist. If you are offline, it offers to keep the mail in the Outbox to send later.

How to send a mail and what is checked first
Where: Compose › Send
- Tap Send.
- Fix anything the app flags, for example a missing recipient.
- If asked "No Internet connection available. Do you want to send this email in outbox?", tap Yes to queue it.
When to use it
Suresh mistypes a colleague's address. The app tells him it was not found before the mail leaves.
Checks in order
| Check | What you see |
|---|---|
| Recipients | Must be present and valid |
| Attachment size | Over-limit message if too large |
| Attachment reminder | Forgot an attachment? sheet |
| Subject | First tap warns "Subject is empty, click again to send anyway" |
| Unknown address | A message names the address that was not found. It does not stop you sending. |
Good to know
- Mail you send while offline waits in the Outbox.
- If the address check cannot finish in time, the mail is sent anyway.
- The app has no undo send. To take a mail back, use recall on the web.
