Oh no, Outlook’s stuck again while you’re just trying to send a simple email? Yeah, I know—it’s super frustrating. You hit “Send,” and then… nothing.
It just hangs there like it’s taking a nap. And if you’re in the middle of work or sending something important, it can totally throw off your day.
Here’s the thing. Outlook freezing isn’t random. There’s usually a reason behind it, and good news, most of those reasons are easy to fix.
You don’t need to be a tech expert. You just need to know where to look and what to do.
It could be something as small as a weak internet connection or as annoying as a bloated inbox. Sometimes, Outlook just needs a little restart.
And other times, you might have to tweak a few settings or clean up some files. Whatever the case, don’t worry—I’m going to walk you through it all step by step.
So, let’s figure out what’s going wrong and get Outlook back to doing what it’s supposed to do—sending your emails without any drama.
What causes Outlook to hang or freeze?
Let’s talk about what might be going wrong in the background. If Outlook keeps freezing when you try to send an email, it’s usually one of these common issues:
1. Overloaded inbox can slow things down
If your inbox is packed with thousands of emails, attachments, and folders, Outlook can start to lag. It’s like trying to run with a backpack full of bricks.
The bigger the load, the slower it gets. Try clearing out old messages or archiving things you don’t need right now.
2. Outlook might have a software glitch
Like any app, Outlook can run into bugs or glitches. These small issues can cause big headaches—like freezing when you hit “Send.” Keeping Outlook updated helps a lot here.
3. Your internet connection could be the problem
If your Wi-Fi is weak or keeps dropping, Outlook might freeze while trying to send an email. It’s waiting for a stable connection to do its job. So, if your emails are stuck, check your internet first.
4. Corrupted emails make things worse
Sometimes, a bad email or a broken data file can jam everything up. Outlook doesn’t know what to do with it and just… stops. That’s when you’ll need to run a repair tool (we’ll get to that soon).
5. Unnecessary add-ons might be causing trouble
Add-ons are like apps inside your Outlook. Some are great, but others can slow things down or even crash the whole program. If Outlook is freezing, it might be time to turn off the extras.
Okay, now that we know what might be going wrong, let’s fix it.
How to Fix Outlook When It Hangs While Sending Email
You’ve seen the problem—now let’s fix it together. Most of these fixes are quick and easy. You don’t need any special tools, just a bit of time and patience.
#1 Make sure you’re online
Let’s start with the easiest fix. If Outlook is stuck, your internet might be the reason.
Try this:
- Open a web browser and visit any website to see if it loads.
- If not, unplug your router, wait for about 20 seconds, then plug it back in.
- Once you’re back online, reopen Outlook and try sending your email again.
If that worked—great! If not, let’s move on.
#2 Give Outlook a fresh start
Sometimes, Outlook just needs a quick break.
Here’s what to do:
- Close Outlook completely. Don’t just minimize it—make sure it’s fully closed.
- Wait a few seconds, then reopen it.
- Try sending your email again.
This clears out temporary glitches and gives Outlook a clean slate.
#3 Keep Outlook up to date
Running an old version of Outlook? That could be the issue.
Here’s how to check for updates:
- Open Outlook.
- Click on File in the top-left corner.
- Select Office Account.
- Click Update Options and then choose Update Now.
Updates include bug fixes that can stop Outlook from freezing.
#4 Turn off extra add-ons
Add-ons might be useful, but too many can slow things down or cause freezing.
Let’s disable them:
- Open Outlook.
- Click File > Options.
- Select Add-ins.
- At the bottom, choose COM Add-ins and click Go.
- Uncheck the add-ons you don’t need, then click OK.
Restart Outlook and see if it works smoother now.
#5 Fix data files using SCANPST tool
Outlook uses special files to store your emails. If one of those files gets damaged, things can go haywire.
Here’s how to run the repair tool:
- Go to your Microsoft Office installation folder (usually in Program Files).
- Find and open SCANPST.EXE.
- Click Browse and locate your Outlook data file (usually ends in .pst).
- Click Start to let the tool scan and fix issues.
After the scan, restart Outlook and try sending that email again.
#6 Keep your inbox clean
Delete old emails, empty your spam and trash folders, and archive what you want to keep. A lighter inbox means faster Outlook.
#7 Simplify your email rules
Too many rules filtering your emails? That can slow things down. Keep only the ones you really need.
#8 Use Task Manager when Outlook freezes
If Outlook locks up, open Task Manager and end the process.
- Press Ctrl + Shift + Esc to open Task Manager.
- Find Outlook.exe under the Processes tab.
- Click End Task.
#9 Clean up your computer
Too many apps or files? That’ll slow everything down. Uninstall things you don’t use and run disk cleanup tools regularly.
#10 Use a trusted antivirus
A good antivirus keeps your internet connection safe—and that helps Outlook, too. Make sure your security software is up to date.
The Takeaway
Outlook freezing when you send an email is annoying. But it’s usually not a huge deal. Most of the time, it’s something simple like a weak internet connection, a full inbox, or a software hiccup.
We talked about restarting Outlook, updating it, turning off unnecessary add-ons, and even fixing corrupted files with the SCANPST tool.
These steps are easy to follow and don’t take much time.
One thing people often get wrong? They think the problem is too big to fix themselves. But honestly, you’ve got all the tools you need right here.
Stay on top of your inbox, keep Outlook updated, and don’t overload it with too many extras. Do that and you’ll rarely have to deal with these freezes again.
