Hey there, busy professionals! We know that feeling when you've crafted the perfect email at 11 PM but you definitely don't want to hit send until tomorrow morning. It's like having that brilliant idea in the middle of the night but knowing you should wait until business hours to share it, right? We've been there too, and honestly, Outlook's email scheduling feature is one of those tools that can be a real lifesaver for your professional communications.
Here's the thing: we've found that most professionals use Outlook daily but many don't realize just how easy it is to schedule emails for later delivery. Whether you're trying to respect your colleagues' after-hours time, coordinate with different time zones, or just want to appear more organized (we won't judge!), email scheduling is a simple feature that can make a huge difference in your workflow. Think of it as your personal assistant that never sleeps, making sure your messages land at exactly the right moment.
In this guide, we'll walk you through the exact steps to schedule emails in both Outlook desktop and web versions, help you troubleshoot common issues when things don't go as planned, and share some pro tips for making the most of this feature. Plus, we'll show you how proper email timing connects to better deliverability, which is something we think about a lot here at mailfloss when helping businesses clean up their email lists and improve their sender reputation.
Scheduling Emails in Outlook Desktop
Scheduling emails in the desktop version of Outlook is pretty straightforward once you know where to look. The feature is called "Delay Delivery" (not "Schedule send" like in some other email platforms), and it's tucked away in the Options menu. We find that most people miss it because they expect it to be more prominent, but Microsoft has kept it in the same spot for years.
Start by composing your email as you normally would. Write your message, add your recipients, attach any files, and get everything ready to go. Here's where the magic happens: instead of clicking that big Send button, look for the "Options" tab at the top of your compose window. Click on it, and you'll see a "Delay Delivery" button in the ribbon. This is your gateway to email scheduling bliss!
When you click "Delay Delivery," a dialog box will pop up with several options. The one you want is "Do not deliver before" with checkboxes for date and time. Check both boxes, then set your desired delivery date and time. You can schedule emails days, weeks, or even months in advance. Once you've set your timing, click "Close" and then hit "Send." Your email will sit patiently in your Outbox until the scheduled time arrives.

One quick thing to keep in mind: your computer needs to be running Outlook at the scheduled time for the email to actually send. By default, Outlook desktop checks for new messages and processes scheduled emails every 30 minutes, but you can adjust this timing in your Send/Receive settings if needed. Just don't set it to less than 5 minutes, as that can cause issues with your mail server.


Using Send Later in Outlook Web
The web version of Outlook (what you access through your browser) handles email scheduling a bit differently, but it's actually even simpler in some ways. Microsoft calls this feature "Send later," and they've made it much more accessible than in the desktop version. We love how they've streamlined this process for the web interface.
Compose your email just like you normally would in the web interface. Get everything perfect, add your recipients, and make sure your message is exactly how you want it. Now, instead of clicking the regular "Send" button, look for the small dropdown arrow right next to it. Click that arrow, and you'll see "Send later" as one of your options. It's that simple!
When you click "Send later," you'll get a clean, modern interface where you can pick your date and time. You can choose from some preset options like "Tomorrow morning" or "Next week," or you can set a custom date and time that works perfectly for your needs. Once you've made your selection, click "Send" and your email will be scheduled for delivery.
The beauty of the web version is that you don't need to worry about keeping your computer running or Outlook open. Microsoft's servers handle the scheduling for you, which means your emails will go out even if you're on vacation in the Bahamas (lucky you!). This makes the web version particularly reliable for important scheduled communications.

Troubleshooting Common Scheduling Issues
We'd love to tell you that email scheduling always works perfectly, but the reality is that you might run into some hiccups along the way. Don't worry though, most issues are pretty easy to fix once you know what to look for. We've helped countless businesses solve email delivery problems, and these scheduling glitches are usually just minor bumps in the road.
One of the most common problems people report is the "last chosen" time displaying incorrectly for scheduled emails. Some users report bugs with the email scheduler, such as the "last chosen" time displaying incorrectly for scheduled emails, which can cause confusion when you're managing multiple scheduled messages. If you notice this happening, double-check your scheduled emails by looking in your Outbox (desktop) or Drafts folder (web) to confirm the actual send times.

Another frustrating issue is when scheduled emails get stuck in your Outbox or don't send at all. This usually happens with the desktop version when there are synchronization problems, especially if you're using Outlook with Gmail or if you've been working offline. The solution is typically to restart Outlook, check your internet connection, or manually send the stuck emails by double-clicking them in your Outbox and hitting send again.
If you can't find the scheduling options at all (the "Delay Delivery" or "Send later" features are missing), you might be using an older version of Outlook or there could be an issue with your account settings. Try updating Outlook first, and if that doesn't work, check with your IT department or Microsoft support forums for account-specific troubleshooting steps.
- Check your Outbox regularly for stuck scheduled emails
- Restart Outlook if scheduled emails aren't sending properly
- Verify your internet connection before scheduling important emails
- Update Outlook if scheduling options are missing
- Double-check scheduled times, especially when managing multiple messages

Pro Tips for Better Email Timing
Now that you've got the technical stuff down, let's talk strategy! Email timing can make a huge difference in whether your messages get read, and we've learned a lot about this from our work at mailfloss helping businesses improve their email deliverability. The best scheduled email in the world won't matter if it's going to invalid addresses or landing in spam folders.
Think about your recipient's schedule when choosing send times. For business emails, aim for Tuesday through Thursday between 10 AM and 2 PM in their time zone. Avoid Monday mornings (everyone's catching up from the weekend) and Friday afternoons (people are mentally checking out for the weekend). If you're emailing internationally, scheduling becomes even more critical for hitting those optimal windows.
Here's something most people don't consider: batch your scheduled emails to avoid overwhelming your recipients. If you need to send multiple emails to the same person, spread them out over several hours or days. Nobody likes to open their inbox and find five emails from the same sender all at once. It's like getting five phone calls in a row, it just feels overwhelming.
For email marketing campaigns (which is where our mailfloss customers really see the benefits), proper timing combined with clean email lists can dramatically improve your open rates and engagement. If you're scheduling marketing emails, make sure your list is clean and up-to-date first. There's no point in perfectly timing an email that's going to bounce or end up in spam because of deliverability issues.

Managing Multiple Scheduled Emails
Once you start using email scheduling regularly (and trust us, you will!), you'll want to keep track of what you've scheduled and when it's going out. This becomes especially important when you're juggling multiple projects or communicating with different teams across various time zones. We've seen professionals schedule dozens of emails at once during busy periods, and organization becomes key.
In Outlook desktop, your scheduled emails will sit in your Outbox until they're sent. Make it a habit to check this folder regularly, especially before important deadlines or meetings. You can double-click any scheduled email to modify the content or change the send time if plans change. Just be careful not to accidentally send it immediately by clicking the regular Send button instead of going back through the Delay Delivery options.
For the web version, scheduled emails appear in your Drafts folder with a small clock icon indicating they're scheduled. You can edit or cancel these emails up until they're sent, which gives you flexibility if situations change. We recommend creating a simple spreadsheet or using your calendar to track important scheduled emails, especially for time-sensitive business communications.
Consider using Outlook's categories or flags to color-code your scheduled emails by project, priority, or recipient type. This visual organization system can be a lifesaver when you're managing complex communication schedules. Think of it like organizing your closet, everything has its place and you can find what you need quickly.
- Set up a weekly review of your scheduled emails
- Use categories to organize scheduled messages by project or priority
- Create calendar reminders for critical scheduled communications
- Keep a backup list of important scheduled emails in case of technical issues
Email Scheduling and Deliverability
Here's where our expertise at mailfloss really comes into play: even perfectly timed emails won't reach their destination if your email list has deliverability issues. We see this all the time with our customers who master the timing aspect but struggle with emails bouncing or landing in spam folders. It's like having the perfect dinner party planned but sending invitations to addresses that don't exist anymore.
When you're scheduling emails, especially for marketing campaigns, make sure you're sending to valid, engaged email addresses. Invalid emails, spam traps, and unengaged subscribers can hurt your sender reputation, which affects whether your carefully scheduled messages actually reach their intended recipients. This is particularly important for businesses that rely on email marketing for customer communication and sales.
If you're using platforms like Mailchimp, HubSpot, or Constant Contact for your scheduled email campaigns, consider integrating an email verification service like mailfloss to automatically clean your lists. We work with over 35 email service providers to keep your lists clean and your scheduled emails landing in inboxes instead of spam folders.
The timing of your scheduled emails can also impact deliverability. Sending large batches of emails all at once can trigger spam filters, even if your list is clean. Instead, consider staggering your scheduled sends over several hours or using your email platform's built-in delivery optimization features. It's better to have your emails arrive in smaller waves than to have them all blocked as potential spam.
Pro Tip: Before scheduling important email campaigns, run your list through an email verification service to remove invalid addresses and improve deliverability. Clean lists plus good timing equals better results!

Conclusion
There you have it! Email scheduling in Outlook doesn't have to be mysterious or complicated. Whether you're using the desktop version with its trusty "Delay Delivery" feature or the more modern "Send later" option in Outlook web, you now have all the tools you need to time your emails perfectly.
Here's what we recommend you tackle first: start with scheduling just one or two emails this week to get comfortable with the process.
