If delayed emails aren’t visible, the location depends on which Outlook feature and version is being used:
- New Outlook or Outlook on the web
- Scheduled messages stay in the Drafts folder until the delivery time.
- Open Drafts, open the scheduled message, then use Edit if needed.
- If the message should go out immediately, open it and select Send Now.
- Important: this scheduling feature isn’t available for IMAP or POP accounts in new Outlook.
- Classic Outlook – single delayed message using “Do not deliver before”
- The message stays in the Outbox until the scheduled delivery time, not in Drafts or Sent Items.
- Open Outbox and look for the delayed message there.
- To send it immediately: open the message in Outbox > More options arrow in the Tags group > under Delivery options, clear Do not deliver before > Close > Send.
- Outlook must be online and connected for this feature to work.
- Classic Outlook – all messages delayed by a rule
- Messages also remain in the Outbox for the configured delay period.
- Check whether a rule is delaying sent mail:
- File > Manage Rules & Alerts
- Review rules on the Email Rules tab
- Look for defer delivery by # minutes in the rule description
- Open the rule and clear that action if it should not apply
- Rule-based delay can hold messages for up to 120 minutes.
- If a delayed message in Classic Outlook opens without a Send button
- Close the message and reopen it.
- That restores the ability to edit and resend in the documented scenario.
- If the message still can’t be found
- In Exchange Server environments, delivery status can be checked through a delivery report, where delayed mail may show as Deferred or Pending.
