Schedule a Follow-Up Email in Outlook: Steps & Tips

To schedule a follow-up email in Outlook, write the message, open the arrow beside Send, choose Schedule send, and select a time. In classic Outlook for Windows, use Options > Delay Delivery and set Do not deliver before. The exact option depends on which Outlook version you use—and scheduling a message is different from setting a reminder to follow up.

Choose what “follow-up” means

People use “follow-up email” to mean two different things. You may want to write a message now and have Outlook send it later—for example, to check in with a customer a few days after a meeting. Or you may want Outlook to remind you to respond to an email you received. The first task uses scheduled sending; the second usually uses a flag or reminder.

Scheduling is useful when you already know what you want to say and when it should arrive. A reminder is better when your next action depends on what happens in the meantime. For instance, if you are waiting for a colleague to provide figures, a reminder to check in next Tuesday is safer than scheduling a message that might no longer be appropriate.

Keep in mind that a scheduled email is not a promise that the recipient will read or act on it. It only controls when Outlook attempts to send the message. Delivery can still be affected by account settings, connectivity, or the recipient’s mail system.

Schedule send in new Outlook or Outlook on the web

In new Outlook for Windows and Outlook on the web, a scheduled message is generally held for delivery by the mail service. You do not normally need to leave the Outlook app open for it to send at the chosen time.

Select New mail and write your message. Add the recipients and subject, and attach any files you want included.
Select the small arrow beside Send. Do not select the main Send button, which sends the message immediately.
Choose Schedule send. Select one of the suggested times or choose the option to set a custom time.
Review the date and time, then confirm the schedule. Look for the message in the Scheduled folder.

The labels and available suggested times can vary slightly as Microsoft updates Outlook. Check the displayed date, time, and time zone before confirming—especially if you are traveling or scheduling a message for someone in another region. The chosen time is when Outlook is instructed to send, not necessarily when every recipient’s inbox will display it.

Outlook for Mac also offers scheduled sending in supported versions. In newer Outlook for Mac, look for the arrow beside Send and choose Schedule Send. In older or legacy Mac layouts, the equivalent command may be labeled Send Later. If neither appears, check that Outlook is up to date and that your account and version support the feature.

Schedule a message in classic Outlook for Windows

Classic Outlook uses a different method called Delay Delivery. It sets a not-before time on a message that is waiting in the Outbox; it does not use the same Scheduled folder workflow as new Outlook.

Start a new email and fill in the recipients, subject, and message.
Open the Options tab on the message ribbon.
Select Delay Delivery. Depending on the ribbon layout, this may be in the More Options group.
Under Delivery options, select Do not deliver before, then enter the date and time.
Close the properties window and select Send. The message remains in the Outbox until its delivery time.

In classic Outlook, the message may depend on Outlook being open and connected when it is due, particularly with POP or IMAP accounts. To avoid a missed send, leave Outlook running and connected until the scheduled time, or verify how your work or school Exchange account handles delayed messages. If the computer is asleep, Outlook is offline, or the account is disconnected, delivery may be delayed until the connection is restored.

Classic Outlook for Mac does not use the Windows ribbon path above. Depending on the version, use the send menu’s Send Later command or the scheduling option beside Send. Menu names and behavior can differ between legacy and new Outlook for Mac, so confirm the message appears in the relevant scheduled or outbox area after setting it.

What happens after you schedule it

Before the scheduled time, the message has not been sent to the recipient. In new Outlook or Outlook on the web, you can usually find it in Scheduled. In classic Outlook for Windows, find it in Outbox. These folders matter: a message sitting in Drafts has not necessarily been scheduled, and a message in Sent Items has already been sent.

Scheduling does not automatically send a second reminder if the recipient does not respond. If you want to check whether they have replied, create a separate reminder for yourself. Also consider whether the message includes anything that could become outdated, such as a meeting link, a price, or a reference to an event happening “tomorrow.” A scheduled message can become inaccurate if circumstances change before it goes out.

For a time-sensitive business message, allow for the possibility of a delay rather than choosing the exact last minute. If the recipient must receive information before a meeting, sending it earlier gives you time to notice a problem and contact them another way.

Edit, cancel, or reschedule a message

It is worth checking a scheduled message before its send time. You might spot a typo, learn that the recipient has already replied, or decide the message should go out sooner.

New Outlook or web: Open the Scheduled folder and select the message. Use the available edit or cancel option. If you cancel sending, Outlook typically returns the message to a draft so you can change it or discard it.
Classic Outlook for Windows: Open the message in the Outbox. You can revise it while it is still waiting. To remove the delay, open Options > Delay Delivery, clear Do not deliver before, and send it when ready.
Outlook for Mac: Open the scheduled or queued message and use the available edit, cancel, or send-now controls. The folder and wording depend on whether you use new or legacy Outlook.

If the scheduled time has already passed and the message has moved to Sent Items, canceling the schedule will not recall it. Outlook’s recall feature, where available, is separate and has limitations; it should not be treated as a reliable way to undo an email delivered to an external recipient.

Use a reminder when you need to follow up later

If you need Outlook to remind you to act rather than send a prepared message automatically, flag the relevant email. In Outlook, select or open the message and use the Follow Up or flag control to choose a due date. Depending on your Outlook version, you can also add a reminder or manage the flagged item through Microsoft To Do.

A flag is personal task tracking: it does not send a follow-up email to the sender. This distinction prevents a common misunderstanding. Marking an incoming message for follow-up does not tell the other person that you will reply, and it does not create an automatic response. When the reminder appears, you decide whether to reply, call, or take another action.

For example, if a supplier says they will send a quote by Friday, flag the message for Monday. If the quote has not arrived, write a new email then. If you already know you want to send a polite status check on Monday regardless, schedule that email instead—but review it before scheduling if the supplier may respond in the meantime.

Choose the right timing and write a useful follow-up

There is no universal best time to send a follow-up. Consider the reason for the message, the recipient’s working hours, and any deadline you agreed on. A brief check-in after a meeting may be appropriate the next business day; a reminder about a proposal may be better after the response window you gave has passed. Avoid scheduling repeated nudges so close together that they feel like pressure.

Make the message understandable on its own. The recipient may not remember the earlier conversation, so include a short reference and a clear next step. For example: “Hi Maya, I’m following up on the draft budget I sent Tuesday. Could you let me know by Thursday whether the revised totals work for your team?” This is more actionable than “Just checking in” because it gives context and a reasonable response request.

Use a subject line that identifies the topic, such as “Follow-up: Thursday project review.”
Keep the opening courteous and concise; avoid implying that a delayed reply was intentional.
Check names, dates, links, and attachments before scheduling.
Set a reminder for yourself if you will need to act again when no reply arrives.

For sensitive or consequential messages, consider saving a draft and reviewing it later instead of scheduling it automatically. That gives you a chance to account for new information before it leaves your Outbox or Scheduled folder.

Common scheduling problems and fixes

The schedule option is missing. Confirm that you are composing a new message and selecting the arrow beside Send rather than the Send button itself. The option can also depend on the Outlook version, account type, or organization’s settings. Update Outlook if appropriate, or use Delay Delivery in classic Outlook for Windows when available.

The message did not go out on time. In classic Outlook, check whether the message is still in the Outbox, whether Outlook was online, and whether the computer was asleep. For POP or IMAP accounts, keep Outlook open and connected through the scheduled time. In new Outlook or web, check the Scheduled folder and account connection, then verify that the message did not remain queued or return an error.

The message went immediately. You may have selected the main Send button instead of the arrow menu, or sent a message after clearing its delay. Check Sent Items to confirm what happened. If it was delivered, scheduling controls cannot reverse delivery.

The scheduled time looks wrong. Review the date, clock, and time-zone settings shown in Outlook and on your device. Be especially careful when traveling, using a shared computer, or coordinating with people in different time zones. Do not assume a recipient’s local time is automatically the time you selected.

You cannot find the message. Search Scheduled, Outbox, and Drafts, and check Sent Items if the time has passed. The correct location depends on how the message was scheduled and which Outlook version you used. If the message is important, verify its status rather than assuming it will send.

Frequently Asked Questions

Can I schedule a follow-up email in Outlook without keeping my computer on?
With new Outlook or Outlook on the web, scheduled sending is generally handled by the mail service, so Outlook does not normally need to stay open. Classic Outlook’s behavior depends on the account; for POP or IMAP, keep Outlook running and connected until the send time.

Does Outlook send a follow-up automatically if someone does not reply?
No. Schedule send delivers one message at the time you choose. It does not monitor replies or send another email automatically. Use a reminder or flag to prompt yourself to check for a response.

Can I schedule an email in Outlook on my phone?
Scheduling options can vary by Outlook mobile app version and account. If the app shows a schedule-send option beside Send, select it and confirm the time. If it does not, schedule the message in Outlook on the web or a supported desktop version instead.

Can I change a scheduled email in Outlook?
Usually, yes, as long as it has not been sent. Find it in Scheduled or Outbox, open it, and use the available edit or cancel controls. The steps depend on the Outlook version. Once it appears in Sent Items, it has already been sent.

Is a follow-up flag the same as scheduling an email?
No. A flag or reminder helps you remember to take action; it does not send a message. Schedule send queues a specific email for delivery at a chosen time.
