How to Schedule an Email in Outlook Mobile

To schedule an email in Outlook mobile, write your message, tap the three-dot menu in the compose window, choose Schedule Send, and select a delivery time. The message will be sent at the time you choose, so you can prepare it now without sending it immediately. You’ll need the Outlook app, access to the account you want to send from, and a recipient and message ready to review.

What You’ll Need

The Outlook app on an iPhone or Android phone. Update it if you cannot find the scheduling option; menus and feature availability can differ by app version and account type.
Access to the mailbox you want to use. Check the From address before scheduling if you have more than one account connected.
A recipient and a prepared message. You can enter these before or after opening the scheduling menu, but reviewing them before you set the time helps prevent a wrong-recipient or incomplete-message problem.
A delivery date and time in mind. Outlook shows the choices available for your account. If it offers a custom time, check the date and time displayed before confirming.

Step-by-Step

Open Outlook and start a message. Open the Outlook app on your iPhone or Android phone, make sure you are in the correct account, and tap the compose button. It may look like a pencil or a square with a pencil, often near the lower corner of the screen. If Outlook opens a different mailbox, use the account or profile control to switch before composing.
Fill in the email as usual. Add the recipient in the To field, and add people in Cc or Bcc if needed. Enter a clear subject and write the message. If you are sending an attachment, add it now and wait until it has finished uploading. A large file or weak connection can delay the attachment, so do not schedule until you can see it in the message.
Check the sending account and message details. If you have multiple accounts, verify the From address; it may be shown as a field or available by tapping the account address. Confirm the recipient spelling, subject, attachment, and any dates or links in the message. Scheduling does not give you a special review window after delivery, so treat this as your final check before setting the send time.
Open the message options. In the compose window, tap the three-dot More menu, usually near the top of the screen. Look for Schedule Send. The precise position and wording can vary with Outlook updates and phone size. Do not tap the regular Send button if you want the email to wait; regular Send sends it right away.
Choose when it should be sent. Tap Schedule Send, then select one of the suggested times if one suits you. To send at another time, choose the custom date-and-time option if it appears, set the date and time, and check that the displayed choice is correct. The time is based on the time zone shown by your device or Outlook settings. If you are scheduling around a recipient’s workday in another time zone, calculate that difference before confirming.
Confirm the schedule. Tap the confirmation button, which may say Schedule, Send later, or similar. Wait for Outlook to finish the action and return to the mailbox or show a confirmation. If the app presents a final summary, verify the date and time there. If you do not see a confirmation or the message disappears unexpectedly, check the relevant mailbox folders before trying again; otherwise, you could create a duplicate.
Find the scheduled email and verify it is waiting. Look in Drafts or a Scheduled folder if your version shows one. Folder names and storage behavior can vary by account and Outlook version. Open the message if necessary and confirm its recipient, subject, and scheduled time. If you cannot find it, refresh the mailbox and check that you are viewing the same account from which you composed it.
Edit or cancel it if your plans change. Open the scheduled message from the folder where Outlook placed it. If available, use Cancel Send or the schedule controls to stop delivery; Outlook may return the message to Drafts so you can edit it or choose another time. Review the screen before leaving, because changing the text is not always the same as changing the scheduled status. If your app offers no cancellation control, check Outlook on the web or contact your organization’s support team before the delivery time.

After scheduling, you generally do not need to keep Outlook open or leave your phone online for the email to send when the account supports server-side scheduling. However, do not assume that every connected account handles scheduled messages the same way. Confirm the message appears as scheduled, and check the account’s folder or status before relying on it for an important deadline.

Common Mistakes

Tapping Send instead of Schedule Send. The regular Send control delivers the message immediately. Open the three-dot menu and select the scheduling option before confirming.
Choosing the wrong account. People with personal and work mailboxes connected to Outlook can accidentally schedule from the wrong address. Check the From field and the destination mailbox before scheduling.
Mixing up the delivery date or time. A suggested option such as “tomorrow morning” may be convenient, but it is easy to overlook the actual date. Read the confirmation and consider your local time zone, especially when coordinating across regions.
Assuming an attachment has finished uploading. An attachment that is still loading may not be included as expected. Wait for it to appear in the message, and open or preview it if the file is important.
Leaving a placeholder or incomplete draft in the message. Scheduling is not a reminder to finish the email later. Check names, links, subject, attachment, and message text before you confirm.
Scheduling twice after a slow response. If Outlook seems to pause, check Drafts or Scheduled before repeating the steps. A delayed confirmation does not necessarily mean the first attempt failed.

Tips

Use a clear subject line. A subject such as “Revised meeting agenda for Thursday” makes the email easier to identify if you need to edit or cancel it later.
Allow a little room before a deadline. If a message must arrive before a meeting or submission cutoff, schedule it early enough to handle a typo, connection issue, or account problem. Scheduling sets a send time; it does not guarantee when another person’s mail service will display the message.
Check the recipient’s time zone. Outlook schedules based on the time shown in your app or device, not the recipient’s local clock. For example, if you choose 9 a.m. in your time zone for someone several hours ahead, the email may arrive during their afternoon.
Keep important scheduled messages easy to find. Once you schedule an email, note the subject or check the Scheduled or Drafts folder so you can locate it quickly. This is useful for a message that contains a time-sensitive announcement or an attachment you may need to update.
Use a test message to learn an unfamiliar layout. If you have just updated Outlook or connected a new account, schedule a harmless message to yourself for a short time in the future. Confirm where it appears and how cancellation works before relying on the feature for an important email.
Remember that cancellation has a deadline. Once Outlook has sent the message, canceling its schedule is no longer possible. If you change your mind, open the scheduled item and cancel it before the listed delivery time.

Troubleshooting

“Schedule Send” is missing. Update Outlook from the App Store or Google Play, close and reopen the app, and check the three-dot menu while a message is open. Confirm that you are using the Outlook mobile app rather than a phone’s separate mail app. The feature can depend on the account type, app version, and organization settings. If it remains unavailable, try Outlook on the web or ask your workplace administrator whether scheduling is enabled for your mailbox.

The message is not where you expected. Refresh the mailbox, confirm the correct account is selected, and inspect both Drafts and any Scheduled folder. Outlook can display or store scheduled messages differently depending on the account and version. Search for the subject if you have several drafts. If it is not in either location, check Sent Items before composing again, since the message may already have gone out.

The scheduled time looks wrong. Open the message and inspect its schedule details before the send time. Check the phone’s date, clock, and time-zone settings, and compare those with the time Outlook displays. If the wrong time is set, cancel or change the schedule and confirm the new time. Be especially careful when traveling, because a changed device time zone can make a planned local-time delivery confusing.

The email did not send at the expected time. First check Sent Items and the scheduled-message location to see whether it sent, remains queued, or was returned to Drafts. Check for a failed sign-in, mailbox restriction, organization policy, or an attachment that could not upload. Refresh Outlook and, if possible, inspect the same mailbox in Outlook on the web. For a work account, your administrator can check mailbox or service issues. Do not create another copy until you know whether the original was sent.

You cannot edit or cancel the scheduled message. Make sure you opened the scheduled item rather than a separate copy of the draft. Look for a cancel or reschedule control in the message or its options menu. If the mobile app does not show one, use Outlook on the web with the same mailbox. If the delivery time has already passed, check Sent Items: once sent, the email cannot be recalled reliably through the scheduling control.

The email sent without its attachment or to the wrong person. Check Sent Items to confirm what was actually delivered. Scheduling cannot correct a message after dispatch. If necessary, send a brief correction or follow-up with the right file or recipient details, and review the original message before taking further action.

Frequently Asked Questions

Can I schedule an email in Outlook mobile on both iPhone and Android?
Yes, the Outlook app supports scheduled sending where the feature is available for the account. The layout and exact menu labels may differ slightly between iOS, Android, and app versions.

Does my phone need to be on when the email is due to send?
Usually not when scheduling is supported by the account’s mail service; the service handles delivery. Still, verify that Outlook confirmed the schedule and that the message appears in Drafts or Scheduled. Account-specific behavior can vary.

Can I schedule a message to send later today or at a custom time?
Often, Outlook offers suggested delivery times and may provide a custom date-and-time choice. The available choices can vary. Review the actual date and time Outlook displays before confirming.

Can I change a scheduled email after I set it?
In many versions, you can open the scheduled message, cancel its pending send, edit it, and schedule it again. Look for the cancellation or scheduling control; if it is missing in the app, try Outlook on the web.

Will Outlook tell me if the email fails to send?
Outlook may show a delivery or sign-in problem, but do not rely only on a notification. Check the scheduled item, Sent Items, and any error message in the mailbox. For a time-critical work email, confirm delivery through an appropriate follow-up channel.

Can I schedule an email from a connected Gmail or other account?
Availability and how the scheduled message is handled can depend on the connected account and Outlook version. If the Schedule Send option is missing, check that provider’s own app or webmail, or use Outlook on the web if it supports scheduling for that mailbox.
