Scheduling an email in Outlook helps when you are working across different time zones, or you want to create drafts for a future event that will be sent automatically on a specific date. Whatever the reason is, the main concern here is how to schedule an outgoing email in Outlook.
Well, Outlook, being one of the feature-rich platforms, facilitates scheduling an email in the easiest way possible. In Outlook, you can schedule an email after writing the message and specifying the recipient's address. In this blog, we will walk you through the steps to schedule an email in Outlook on the Web, classic Outlook, and New Outlook. Additionally, we will also discuss how you can cancel and edit scheduled emails in Outlook.
There are multiple benefits to schedule an email to be sent in Outlook. Some of them are:
From marketing to the health industry, every organization is using the email scheduling feature in Outlook. In the next section, we will go through the actual procedure to schedule an email in Outlook.
If you are an Outlook user, you must know that there are three different versions of Outlook, namely classic Outlook, Outlook on the Web, and New Outlook. The steps for email scheduling differ for different Outlook versions.
In this section, we will explore the methods to schedule an email to be sent in Outlook’s different versions. Follow the steps according to the type of Outlook you are using:
The steps below will work in all versions of classic Outlook, including Outlook 365, Outlook 2024, 2021, 2019, 2016, and earlier versions. Here are the steps one needs to follow to schedule an email in classic Outlook:
Step 1: Launch Outlook and click on the New Email button located at the top left corner of the interface.
Step 2: Compose a new email, then click on the Options tab >Delay Delivery. If you do not see the Delay Delivery option in the menu bar, click the three-dot icon or more options button to find it.
Step 3: In the Properties dialog box, under Delivery options, select Do not deliver before. Set the date and time of delivery and click the Close button.
Step 4: Click the Send button, and the email will be saved and delivered on the specified date and time of delivery.
Below are the steps to schedule an email in Outlook on the Web. Follow them carefully:
Step 1. Log in to your account in Outlook.com and click on New Mail.
Step 2. Compose a new email.
Step 3. Click on the down arrow button next to Send, then Schedule send.
Step 4. Set time and date, then click Send.
Step 5. The email message will be scheduled, and you will receive a notification saying Send scheduled for this XXYY.
Starting from Windows 11, the New Outlook user base is growing steadily. Therefore, there are many users who want to know how to schedule an outgoing email in New Outlook. The steps are similar to the Outlook on the Web, but there is a limitation. The scheduling feature is not available for users who are using an IMAP or POP account with New Outlook.
You must have either an Exchange, Office 365, or Outlook.com account to schedule an email in the New Outlook. The steps for scheduling emails are:
Step 1: Open New Outlook and click on New.
Step 2: Compose the email and then click the arrow button next to Send.
Step 3: Select the Schedule Send option.
Step 4: Choose the default time and date or specify a new date/time by clicking on the Customize time option.
Step 5: Finally, click Send.
The email will be saved temporarily to the Drafts folder and will be sent automatically at your specified date and time.
Often, after scheduling an email, the need arises to add or remove recipients or change the email content. Also, sometimes, you may need to discard or cancel the complete email. Outlook allows you to modify or cancel a scheduled email in Outlook. However, this option is only for those emails that have not yet been sent. To make changes to the email, you need to know where it is.
As I said above, every email that you schedule is not immediately sent to the target email address. After you click the Send button, that email is moved to the Drafts folder in Outlook on the Web and New Outlook. While the classic Outlook users can find it in the Outbox folder.
After finding the email in the Drafts or Outbox folder based on your Outlook version, open it and modify it as per your need, and then click Send. The email will be saved with the latest changes and will auto-deliver at the time you had specified earlier. You can use the same process to change the delivery time and date of the email.
To delete a scheduled email in Outlook, find the email and click the delete button next to the subject line of that email. Based on your Outlook version, the interface may vary. Also, if you cannot find the delete icon, open the email and then look for options like "Delete" or "Cancel Send".
Every email that you schedule is not guaranteed to be delivered. There are certain factors that can delay or cause email delivery to fail. Knowing these issues will help you in avoiding failed message delivery errors.
Outlook Closed or Disconnected from Internet
This case is seen in the classic Outlook and especially when you are using the Cached Exchange Mode in Outlook. If the scheduled email remains only on the local cached OST file, Outlook must be running and connected to the internet at the time of delivery. Failing to do so will result in failed delivery. For such an email, you may have to manually open it and send it again.
Incorrect Date and Time
Outlook will only send an email at the time you specified when you scheduled it. If you accidentally choose the wrong year or month, the message will be delayed until that time is reached. Therefore, if your Outbox or the Drafts folder has message in waiting, open them and verify the schedule time and date.
Large Attachments
Microsoft’s official documents say that Outlook may fail to deliver an email (standard or scheduled) having an attachment of size greater than the limit of the destination server. So, make sure the emails that you are scheduling contain attachments only up to the maximum allowed limit. For oversized attachments, prefer OneDrive links.
Corrupted Outlook Profile or Data File
A corrupt Outlook profile or a damaged Outlook data file (OST or PST) can make your mailbox folders inaccessible. In such an event, Outlook will not be able to access or send emails stored in the mailbox and will naturally fail to deliver the scheduled emails as well. This issue is seen in classic Outlook because it relies heavily on the local data files, OST and PST. Outlook on the Web and the New Outlook use a web-based architecture, so OST/PST corruption does not hinder their operations.
To restore email delivery to its natural, correct flow, you have to fix the corruption. If the profile is corrupt, create a new Outlook profile. And if the mailboxes are corrupt, use the appropriate method to fix them.
When you create a scheduled email in classic Outlook, the email is saved in the local Outbox folder. And if your OST file gets corrupted, Outlook may fail to deliver that email at the specified time. Moreover, the issue is not limited to just OST. Since Outlook also depends on PST files, a corrupt PST file also creates issues in accessing emails or folders.
To fix OST, Microsoft recommends deleting the old, damaged file and rebuilding a new OST. However, this approach may result in data loss of the items that were not synchronized with the Exchange Server.
A safer option is to use a dedicated OST repair tool, like the Kernel OST File Repair Tool. The tool supports repairing multiple large OST files and recovering data with original metadata and folder hierarchy.
For PST, you can fix minor corruption using the ScanPST.exe tool, and for more deeply rooted corruption, a professional PST repair tool, like Kernel for Outlook PST Repair, will work better.
Using the steps we discussed in this blog, you will be able to easily schedule an email in Outlook on the Web, classic Outlook, and the New Outlook. In case of any failed or delayed email deliveries, verify the email delivery date and time, and if using the classic Outlook, make sure the Outlook instance is running and connected to a stable internet connection at the time of message delivery.
However, if your Outlook data files are corrupt, repair them immediately to avoid data loss and restore your usual email flow. For severe corruption, do not rely on manual solutions. Save your data and time with professional tools.
