How to Schedule an Email in Outlook for iOS on iPhone

To schedule an email in Outlook for iOS, compose your message, tap the three-dot menu, choose Schedule Send, and select when it should be delivered. The message is then held for delivery at that time, so you do not have to remember to send it later. You will need Outlook installed on your iPhone, access to the mailbox you want to send from, and an internet connection while setting up the scheduled message.

What You’ll Need

An iPhone with the Outlook app installed and a mailbox added to it. Update Outlook from the App Store if you cannot find the scheduling option.
Permission to send messages from the account selected in the compose window. Work or school accounts may be subject to organization policies.
A planned delivery date and time. Check the time zone shown on your iPhone and allow for any difference between your location and the recipient’s.
An internet connection while composing and scheduling. Once Outlook confirms the schedule, the phone generally does not need to remain online for a server-hosted mailbox to send the message.

Step-by-Step

Open Outlook and choose the correct account. Launch Outlook for iOS and tap the mail icon if you are in another area of the app. If you have multiple accounts, check the account shown in the mailbox before composing. The sender address is important: a message scheduled from a work account will not automatically be sent from your personal account.
Start a new message. Tap the compose button, usually shown as a pencil or a square with a pencil. Add the recipient in the To field. You can enter an address or select a contact suggestion, but make sure the final address is correct, especially if Outlook offers several people with similar names.
Write the subject and message. Add a clear subject, then write the email as you normally would. Attach files now if needed and check that they appear in the message. Scheduling changes the delivery time; it does not change the content, recipients, attachments, or sender account.
Review the message before scheduling. Confirm the recipient, subject, wording, and attachments. If the message needs to refer to a date, make sure the date in the text agrees with the time you plan to send it. This is a useful moment to check whether a reply, meeting invitation, or other action is needed before the scheduled message goes out.
Open the message options. In the compose window, tap the three-dot menu, generally near the top-right corner. Outlook’s layout can shift between app versions and iPhone sizes, so look for the ellipsis menu rather than assuming it is in an exact position. Do not tap the paper-plane send button if you want to schedule instead of sending immediately.
Choose Schedule Send. Tap Schedule Send in the menu. If this option is missing, see Troubleshooting below; availability can depend on the app version, mailbox type, and account policies. If Outlook shows suggested delivery times, you can choose one, or select the option to pick a custom time when available.
Set the date and time. Use the date and time picker to choose when Outlook should send the email. Check the day as well as the hour: a time such as 8:00 may be offered for today or the next morning depending on when you are scheduling. For a custom date, move through the calendar to the correct day, then select the intended time. Pay attention to AM or PM if the picker uses a 12-hour clock.
Confirm the schedule. Review the delivery time in the confirmation screen and tap the button that confirms scheduling. Wait for Outlook to finish and show a confirmation that the message is scheduled. If the app returns to the compose window or reports a connection problem, do not assume it was queued; check the message list before trying again to avoid sending duplicates.
Check where Outlook put the message. Look in Drafts first, and also check for a Scheduled folder or an Outbox if your account displays one. Folder names and message indicators vary by account and app version. Open the message if needed to verify the planned time and confirm it is the scheduled copy, not an older draft with similar wording.
Make changes before delivery if necessary. Open the scheduled message from its folder. Depending on the mailbox and Outlook version, you may be able to cancel the send, edit the message, and schedule it again. If Outlook shows a cancel or unschedule action, use it before editing; changing an unrelated draft may not alter the queued message. Confirm the new schedule after making changes.

After scheduling, leave the message in the account rather than deleting it or moving it to another service. For most server-connected mailboxes, Outlook’s service handles delivery at the chosen time. If your account uses a connection or provider for which Outlook cannot keep a scheduled message on the server, the app may behave differently or may not offer this feature. The confirmation and the location of the message are the best clues that scheduling succeeded.

Common Mistakes

Choosing the wrong time or date. Suggested times can be convenient, but they are easy to tap without noticing the day. Read the confirmation carefully, particularly when scheduling near midnight, over a weekend, or across a time-zone change.
Sending immediately by accident. The normal send control and schedule options are separate. Open the three-dot menu and choose Schedule Send before confirming; tapping the send icon delivers the message right away.
Assuming a scheduled message is an ordinary draft. A draft may not have a delivery time attached. Look for a scheduled indicator or the correct scheduled-message folder, and verify that Outlook displayed a success confirmation.
Editing the wrong copy. If you have saved drafts with similar subjects, make sure you opened the scheduled message. A change to a separate draft does not necessarily update the version waiting to be sent.
Forgetting attachments or choosing the wrong sender. Scheduling does not add a missing file or correct the From address. Check both before confirming, especially when switching between personal and work mailboxes.
Assuming the recipient will receive it at the exact displayed second. The selected time is the intended send time, but delivery can take longer because of service delays, connectivity, or recipient mail systems.

Tips

Schedule with a small buffer. If the email must arrive before a meeting or deadline, choose a time early enough to allow for processing and recipient-server delays. A scheduled message is not a guarantee of instant arrival.
Use a specific subject. A subject such as Project update for Tuesday is easier to identify in Drafts than a generic subject such as Update. This also makes it simpler to distinguish the scheduled copy from other drafts.
Check local time when traveling. If you schedule while abroad or change the iPhone time zone, confirm how the selected time is displayed. For an important message, note the intended time in the recipient’s time zone and compare it with the time picker.
Keep the app current. Outlook menus and supported account types can change. Installing the latest version can restore features or make the Schedule Send control easier to locate.
Use scheduling for practical, low-risk timing. It is useful for routine follow-ups, reminders, and messages you want to send during normal business hours. For urgent or time-critical communication, send it yourself and verify delivery rather than relying solely on a scheduled queue.
Check the mailbox after scheduling. A quick check of the scheduled message or its confirmation can catch a failed save while there is still time to send manually or schedule again.

Troubleshooting

Schedule Send is not in the menu. Update Outlook in the App Store, close and reopen the app, and make sure you are composing from the account you intend to use. Some mailbox types, older app builds, or organization settings may not support the option. If it remains unavailable, try Outlook on the web or another supported Outlook client and check your organization’s guidance. Do not assume that a normal draft will send itself later.

The message does not appear to be scheduled. First check for a success notice, then look in Drafts and any Scheduled or Outbox folder available for that account. Refresh the folder and confirm the correct mailbox is selected. If the message is still open in the compose screen, Outlook may not have completed the scheduling action. Reconnect to the internet, try again, and check for an existing scheduled copy before repeating the action.

The time or date looks wrong. Reopen the scheduled message and inspect its delivery time. Check the iPhone’s date, time, and time-zone settings, and compare the selected time with the location you intended. If you cannot edit the queued message directly, cancel or unschedule it if that option is available, then compose or reopen it and schedule it again for the corrected time.

The email was not sent at the expected time. Refresh the mailbox and check whether the message is still waiting in Drafts, Scheduled, or Outbox. Confirm that scheduling was successful and that the account is still connected and allowed to send. Some delivery delay is possible even when the send is processed on time. If it is urgent, open the message, cancel the schedule if possible, and send it manually after checking that a copy has not already gone out.

You cannot find a way to cancel or edit it. Open the scheduled message itself and inspect its available actions; controls differ by account and Outlook release. If the mobile app does not offer the needed control, sign in to the same mailbox in Outlook on the web or another Outlook client and check the scheduled message there. Avoid deleting the entire conversation as a substitute: deleting a visible copy may not cancel a server-side queued message.

Frequently Asked Questions

Can I schedule an email in Outlook for iOS?

Yes, when the Schedule Send feature is available for your Outlook app version and mailbox. Compose the message, open the three-dot menu, select Schedule Send, and choose a delivery time. If the option is absent, update the app and check whether the account or organization supports it.

Does my iPhone need to stay on for the email to send?

For a mailbox that queues scheduled messages on its server, the phone generally does not need to stay on or connected after Outlook confirms the schedule. The message still depends on the account and service being able to send it. If Outlook has not confirmed scheduling, it may only be an unsent draft.

Where can I find scheduled emails in Outlook on iPhone?

Check Drafts first, then look for a Scheduled folder or Outbox. The location and label depend on the mailbox and version of Outlook. Open the message and confirm that it has a scheduled status or delivery time rather than assuming every item in Drafts is queued.

Can I change a scheduled email after setting it?

Often you can open it and cancel or unschedule it, make edits, and schedule it again, but the available controls vary. Verify that you are changing the queued message, not a separate draft. If the app does not provide an editing action, check the same mailbox in Outlook on the web.

Will Outlook send the email if I close the app?

Usually, yes, if Outlook has successfully scheduled the message with a supported server-connected mailbox. Closing the app is different from deleting or canceling the message. Check for the scheduling confirmation before you close Outlook.

Can I schedule an email to arrive at an exact time?

You can choose a delivery time in the picker, but the recipient may see the message later because delivery depends on Outlook and the recipient’s mail service. For a deadline, schedule it with a buffer and do not treat the selected time as a guaranteed arrival time.
