To delay sending an email in Outlook, use Schedule send in new Outlook or Outlook on the web, or Do not deliver before in classic Outlook for Windows. The correct method depends on your Outlook version and account type, and classic Outlook may need to stay open and connected until the message is released.
This guide explains the exact menus, shows a realistic client-update example, and helps you confirm where a delayed message is waiting before you rely on its delivery time.
Which Outlook delay-send option should you use?
Outlook uses similar language for several different features. Scheduling one message for tomorrow is not the same as holding every outgoing message for two minutes so you can catch a mistake. Identify your application first: new Outlook for Windows, classic Outlook for Windows, or Outlook on the web. Microsoft documents separate instructions for each in its delay or schedule sending guide.
| Outlook version | Choose | Where the message waits | Key limitation |
|---|---|---|---|
| New Outlook for Windows | Schedule send | Drafts | Not supported for IMAP or POP accounts |
| Outlook on the web or Outlook.com | Schedule send | Drafts | Confirm the scheduled time and mailbox |
| Classic Outlook for Windows | Do not deliver before | Outbox | Outlook must be online and connected |
| Classic Outlook, every outgoing email | Defer-delivery rule | Outbox | Rule delay is limited to 120 minutes |
Version update: a default delay is also partially available in new Outlook. Microsoft’s September 2026 feature comparison lists the Delay send rule as Available in classic Outlook and Partially available in new Outlook, linking to a default delay-send setting. That does not mean the new experience offers the same Rules & Alerts options as classic Outlook, or that every account/build exposes the setting. The classic two-minute defer-delivery rule below remains the documented example for that workflow; check your account’s current options before assuming the behavior is identical. See Microsoft’s feature comparison.
Use the version-specific scheduling feature for one message, or a classic Outlook rule for a brief correction window.
How do you schedule an email in new Outlook?
- Open New mail and enter the recipient, subject, message, and attachments.
- Review the recipient list, especially any external addresses or reply-all recipients.
- Select the arrow beside Send, then choose Schedule send.
- Choose a suggested date and time, or enter a custom date and time, then confirm Send.
- Open Drafts to find the scheduled message and check that it is still waiting.
For example, you finish a supplier status update at 6:30 p.m. but want it delivered at 9:00 a.m. the next working day. Schedule it for 9:00 a.m. in the recipient’s intended time zone, not merely the time shown on your own clock. The message remains in Drafts. Microsoft notes that Schedule send is unavailable for IMAP and POP accounts in new Outlook.
If you change your mind, open the scheduled message in Drafts, select Cancel send, and then send immediately or revise the message. Do not assume that editing preserves the previous schedule; confirm it again after changes.
How do you schedule an email in Outlook on the web?
- Open Outlook on the web or Outlook.com and create a new message.
- Complete the message and check the attachments before scheduling.
- Use the dropdown next to Send and select Schedule send.
- Pick a suggested time or enter a custom time, then select Send.
- Look in Drafts to confirm the message is scheduled.
This workflow is useful when you prepare a weekly report outside normal office hours but want the message to arrive during the next workday. Unlike the classic desktop Outbox method, web scheduling is handled by the mailbox service; you do not need to leave a browser tab open. The scheduled time does not guarantee inbox delivery at that exact minute.
To send sooner, open the scheduled item in Drafts, cancel the scheduled send, and send it normally. If the item is missing, search the correct mailbox and check Drafts before composing a replacement; otherwise you could accidentally send two copies.
How do you delay one email in classic Outlook for Windows?
- Compose your email in classic Outlook for Windows.
- In the message window, open the Message Options dialog using the arrow in the Tags group. With the simplified ribbon, use the Options tab and its additional commands.
- Under Delivery options, select Do not deliver before.
- Set the intended date and time, select Close, and then select Send.
- Check Outbox. The message should remain there until its scheduled release.
The important difference is where the message waits. In classic Outlook, delayed delivery can depend on the desktop client running and remaining online. Microsoft’s delivery troubleshooting guidance explains why a message deferred to a local Outbox in Cached Exchange Mode may not send while Outlook is closed. A sleeping laptop or disconnected account can therefore defeat an otherwise correct schedule.
If the message must go immediately, open it in Outbox, clear Do not deliver before, close the dialog, and select Send again. Check the final Sent Items record rather than treating the scheduled time itself as proof of delivery.
Can you delay every outgoing email by two minutes?
Yes, classic Outlook for Windows supports a rule that defers outgoing messages for a specified number of minutes, up to 120 minutes. This is useful as a short correction window for accidental recipients, forgotten attachments, or premature replies. It differs from scheduling one message.
- In classic Outlook, open File > Manage Rules & Alerts, then choose New Rule.
- Under Start from a Blank Rule, select Apply rule on messages I send.
- Leave conditions blank only if you intend the rule to cover all outgoing messages; confirm the prompt.
- Select defer delivery by a number of minutes, choose the underlined number, and enter 2.
- Add exceptions if required, name the rule, enable it, and finish.
For an urgent escalation, a blanket rule can be counterproductive because even time-sensitive messages wait. Keep exceptions intentional and review the Outbox when you need to release a message. If your office already uses automatic email rules, our Outlook rules guide explains how to keep important messages visible while automating routine mail.
Worked example: schedule a client update without sending it twice
Imagine a project coordinator has finished the weekly progress summary on Thursday evening. The client expects updates on Friday morning. The coordinator uses new Outlook with a supported Microsoft 365 mailbox and wants a single message to arrive at 9:15 a.m. on Friday.
| Field | Example |
|---|---|
| Recipient | Client project contact |
| Subject | Friday project update — outstanding actions |
| Scheduled send | Friday, 9:15 a.m. in the agreed time zone |
| Attachment | Approved weekly status report |
| Confirmation | One scheduled message visible in Drafts |
A practical message body is: “Please find the approved weekly status report attached. Two items remain open: supplier confirmation by Tuesday and the revised timeline by Wednesday. We will send an updated action list once both are confirmed.” This wording names the deliverable, current exceptions, and next action without implying that an unresolved task is complete.
Before scheduling, the coordinator confirms the attachment is the approved version, checks the recipient’s time zone, and searches Drafts for another copy with the same subject. On Friday, the coordinator checks Sent Items. If the scheduled email is still waiting, they investigate the existing item instead of immediately composing a second message.
Why is Schedule send missing or the message still unsent?
Schedule send does not appear: Check which Outlook application you are using. New Outlook has a dropdown next to Send, while classic Outlook uses delivery options. In new Outlook, the feature is not available for IMAP or POP accounts. An organization may also apply account or application restrictions, so avoid assuming every mailbox behaves identically.
The message is still in Drafts: In new Outlook or the web version, this is normal before the selected send time. Check the scheduled time, time zone, and whether the send was canceled or rescheduled. Search for the original item before starting over.
The message is stuck in Outbox: In classic Outlook, check that the scheduled time has passed and Outlook is open, online, and connected. Also review any defer-delivery rule that might add a second delay. Outbox does not prove delivery.
The recipient says nothing arrived: Confirm the message appears in Sent Items, check the destination address, and ask the recipient to check their mailbox rules or junk folder. If several colleagues monitor a shared address, use a clear ownership process such as the one in our shared inbox triage guide to avoid duplicate follow-ups.
When should you schedule a message rather than send it now?
Schedule send is appropriate when the content is ready but the delivery window matters: a routine weekly update, a nonurgent reminder, or a message prepared across time zones. It is not a substitute for approval. If a manager has not signed off, keep the message as an ordinary draft rather than scheduling a statement that may become inaccurate.
For recurring reports, pair a calendar reminder with the actual preparation deadline. Our recurring deadline calendar guide helps distinguish when the document must be ready from when the email should be sent. If you work across Gmail and Outlook, our Gmail filters guide covers inbox organization, not Outlook scheduling; the two features solve different problems.
Outlook schedule-send and delay-send FAQs
Where can I find an email that is scheduled but not sent yet?
New Outlook and Outlook on the web keep scheduled messages in Drafts until the selected send time. The classic Outlook Do not deliver before method holds the message in Outbox. Find the existing message before creating a replacement to avoid duplicates.
Do I have to leave Outlook open for a delayed message to send?
For classic Outlook’s local Outbox delivery path, the desktop client may need to be running and online when the scheduled time arrives. Web-based scheduling is handled by the mailbox service, so the browser tab does not need to stay open. Check Sent Items afterward; scheduling is not proof of delivery.
Why is Schedule send missing for my IMAP or POP account?
Microsoft says the new Outlook Schedule send feature is not available for IMAP or POP accounts. Check which Outlook version and account type you have before following a set of scheduling steps intended for another version.
Is the new Outlook default delay-send option identical to classic Outlook’s two-minute rule?
No such equivalence should be assumed. Microsoft currently describes new Outlook’s delay-send rule support as partial, whereas classic Outlook provides the documented Rules & Alerts deferral rule. Review the options actually available for your account and avoid copying classic menu paths into new Outlook.
Final checklist before you rely on a delayed email
- Confirm the Outlook version and account type.
- Review recipients, attachments, and approval status.
- Set the intended date, time, and time zone.
- Find the scheduled message in Drafts or Outbox, as appropriate.
- Check Sent Items after the intended time, and investigate the original item before resending.
The safest Outlook delay-send workflow is to use the correct version-specific command, confirm where the message is waiting, and check its final status. That gives you control over timing without confusing a scheduled message with a delivered one.
