How to Schedule an Email in Outlook on the Web (OWA)

To schedule an email in Outlook on the web, compose your message, open the menu beside Send, choose Schedule send (or Send later), and select a delivery time. Outlook holds the message until then, so you can send it at a useful time without keeping the browser open. You’ll need access to your Outlook.com or Microsoft 365 mailbox and a recipient, subject, and message ready to send.

What You’ll Need

An Outlook.com or Microsoft 365 account that you can access in a web browser.
The recipient’s email address and the message content. You can also add attachments before scheduling.
A delivery date and time, with the correct time zone in mind. If this is a work or school account, your organization may control which features are available.

The instructions below are for Outlook on the web, sometimes called OWA. The steps are broadly the same in a browser on Windows or Mac. The Outlook desktop app has a different interface and may offer a different scheduling feature, so make sure you are working at Outlook on the web if the menu names do not match.

Step-by-Step

Open Outlook on the web. Go to Outlook in your browser and sign in to the account you want to send from. If you have more than one mailbox open, check the account name or profile before composing. Scheduling a message in the wrong account can be difficult to notice until the recipient sees the sender address.
Start a new message. Select New mail or New message, depending on the interface. A blank compose pane should appear. If it opens in a small pane, you can use the expand or pop-out control to make writing easier, but expanding the message is optional.
Address the email and write it. Enter the recipient in the To field. Add people in Cc or Bcc if needed, then fill in the subject and message body. Check names in the recipient suggestions carefully: selecting an autocomplete entry can insert a different person with a similar name or address.
Add any attachments now. Use the attachment control to add files, or include a link if the file is stored in OneDrive or another shared location. Wait for an attachment to finish uploading before scheduling. For a large file, confirm that Outlook has finished processing it; a filename that appears in the draft does not always mean the upload is complete.
Open the scheduling menu. Find the small arrow or dropdown control beside the Send button at the bottom of the compose pane. Select it, then choose Schedule send. Some accounts or interface versions may label the option Send later. Do not select the main Send button if you want to delay delivery: that sends the message immediately.
Choose a date and time. Outlook may show suggested times, such as the next morning, as well as an option to choose a custom time. Select the suggestion that fits, or open the custom date and time picker and enter the intended delivery date and time. Check the date, not just the hour; a message set for tomorrow morning is different from one set for this morning. If Outlook displays a time zone, verify it before confirming.
Confirm the scheduled send. Review the selected time and confirm the action in the scheduling window. Outlook should close the compose pane or show a confirmation that the message is scheduled. If you do not see confirmation, check the message location before assuming it was queued. Depending on the account and interface, you may find it in Drafts or a Scheduled folder.
Check the scheduled message if timing matters. Open the folder where Outlook placed it and confirm the recipient, subject, content, attachment, and scheduled time. A scheduled email usually remains editable or cancelable before delivery. If it is important or time-sensitive, check it again well before the send time so there is time to correct a mistake.

Once a message is scheduled, you can close the browser or sign out; the message is queued by Outlook rather than relying on the compose window staying open. At the scheduled time, it is sent from the mailbox you used to create it. After it sends, look in Sent Items if you need to confirm that it left the account. Scheduling is not a guarantee that the recipient’s mail system will deliver it to the inbox; filters, address errors, or outages can still affect delivery.

Common Mistakes

Clicking Send instead of its dropdown. The main button sends immediately. Open the adjacent arrow menu first, then choose the scheduling option.
Choosing the wrong day or time zone. A date picker can open on a different day than expected, especially near midnight or when working across time zones. Read the complete date and time on the confirmation screen rather than relying on a suggested label alone.
Leaving the recipient or attachment unchecked. Scheduling does not make an incomplete message safer. Verify each address and make sure files have uploaded before confirming.
Assuming the message is in Sent Items right away. A queued message has not yet been sent. Check Drafts or Scheduled, not Sent Items, before its delivery time.
Thinking schedule send is the same as a delivery receipt. A scheduled time tells Outlook when to send; it does not confirm when the recipient opens or receives the email.

Tips

Give yourself a review window. For an important announcement, schedule it early enough that you can reopen and check it before delivery. Avoid setting a critical message for a time when no one can resolve an issue.
Use a clear subject and concise opening. The recipient may read the message on a phone or see it among many emails. A specific subject makes it easier to recognize and find later.
Check the sender account and reply path. If you have shared mailboxes or aliases, confirm which address Outlook will use and whether replies should go to that address.
Schedule in the recipient’s working hours when appropriate. For colleagues in another region, convert the intended time before choosing it, then verify Outlook’s displayed time zone. A message arriving during their workday may be easier to act on than one sent overnight.
For recurring announcements, verify every instance. Outlook’s schedule-send control is for a single message, not an automatic recurring email. If you need a repeating process, use an approved workflow or calendar/task reminder rather than assuming one scheduled message will repeat.

Troubleshooting

You cannot find Schedule send or Send later. Confirm that you are composing in Outlook on the web and look for the arrow beside the Send button, not just the main button. If the menu still lacks the option, refresh Outlook, try a supported browser, and check whether your organization has limited the feature. A work or school administrator may need to confirm availability. Avoid relying on a desktop-app instruction if you are using OWA; its menus differ.
You selected a time but are not sure the message queued. Look for an on-screen confirmation, then check Drafts or Scheduled for the message. If it remains an ordinary unscheduled draft, open it and try the scheduling action again. Do not click Send to test the feature unless you are ready for immediate delivery.
The time looks wrong. Reopen the scheduled message and compare its displayed delivery date and time with your intended time zone. Check Outlook’s regional or time-zone settings if available, as well as your device clock. If the message is still queued, cancel or edit it and schedule it again for the corrected time.
You need to change or cancel the message. Open the queued item from Drafts or Scheduled. If Outlook offers Cancel send, select it; the message should return to an editable draft. Make the change, then schedule it again. If you only want to stop delivery, cancel the schedule and leave the message as a draft or delete it. Menu wording can vary, so confirm the message is no longer queued.
The recipient says the email never arrived. Check Sent Items after the scheduled time to see whether Outlook sent it. If it is still in Drafts or Scheduled, the send may not have completed or the time may not have arrived. If it is in Sent Items, verify the exact address and ask the recipient to check junk, spam, quarantine, or other filtered folders. A sent message can still be delayed or rejected after leaving your mailbox.

Frequently Asked Questions

Can I close Outlook after scheduling an email?

Yes. Outlook on the web queues the message in your mailbox, so you do not need to keep the browser tab open or your computer running for the scheduled send to occur. Check the queued message if you want to verify the chosen time before closing.

Where does Outlook store a scheduled email?

It commonly appears in Drafts until its scheduled time, though some interface versions or account types may show a Scheduled folder. If you cannot find it, use Outlook’s search or inspect both folders in the account from which you composed the message.

Can I edit a scheduled email?

Usually, yes. Open the queued message and use Cancel send if Outlook presents that option. The message should return to drafts so you can edit the text, recipients, or attachments. Schedule it again afterward; simply changing a draft may not preserve the original delivery time.

Can I schedule a message to send immediately?

If you want it sent now, select the main Send button. Schedule send is for a later date and time. Some suggested times may be soon, but they are still a delay, so check the selected time if delivery speed matters.

Will Outlook send the email at the exact time I selected?

Outlook queues it for the selected time, but delivery through the recipient’s mail service may take longer. Check the time zone shown when scheduling, and allow for possible processing or network delays if the email must arrive by a deadline.

Does scheduled send work for attachments?

Yes, you can schedule a message with attachments. Add the files before scheduling and wait until each upload is complete. For large files or shared links, confirm that the recipient will have permission to open them when the email arrives.
