Why Is The Spell Check In Outlook Not Working? [2023]

Spell Check in Outlook Not Working

You’re probably wondering why Outlook’s spell check isn’t working.

The spell-check feature in Outlook can be a real lifesaver, ensuring that your emails are error-free and professional. Unfortunately, errors can occur which stop the spell-check from functioning correctly. There are several possible reasons for this, ranging from faulty settings to corrupt files. 

When your Outlook spell check stops working, it could be because of corrupted or missing files in your Microsoft Office installation.

It’s also possible that the AutoCorrect feature is enabled but not configured properly – if so, then disabling AutoCorrect should solve the problem.

Additionally, there may be conflicts between third-party programs and Outlook, such as grammar tools or virus protection software; these too can cause issues with spell-checking features.

Finally, if none of these solutions work then try running a system file checker (SFC) scan to make sure that all of your Windows system files are intact and functional.

In summary then: if you’re facing an issue with Outlook’s spell check not working on replies or other messages then firstly look at whether any config changes need to be made; secondly double-check whether all your Office files are present and correct; finally run a system file checker scan to ensure everything is functioning as expected on your device.

Why is the spell check not working in Outlook?

If your Outlook isn’t flagging typos and grammar mistakes, it could be that the spell checker is not functioning properly.

Here are 4 potential causes for this issue:

  1. You may have an outdated version of Outlook.
  2. The auto-correct feature may be disabled or set incorrectly.
  3. Your language settings in Outlook may need to be adjusted.
  4. There might be a problem with the Windows registry settings associated with Office products.

To troubleshoot these issues, you’ll need to open up Outlook’s Options menu and run through each setting, in turn, to ensure they’re configured correctly for spellcheck operations.

You’ll also want to make sure that your version of Office meets minimum requirements as specified by Microsoft, and check the Windows Registry if necessary to verify any related settings there too.

If all else fails, you should consider reinstalling Office from scratch – though we’d recommend backing up any important documents first!

Other Possible Causes of Why Spell Check Is Not Working

It could be that something’s amiss with the spell checker.

Spell Check in Outlook can malfunction due to a variety of reasons, such as an out-of-date version, language incompatibility, or even malware infections.

The most common cause is when the user has turned off the spell checker either accidentally or deliberately.

This issue can also occur if any third-party add-ons have interfered with the functioning of Outlook’s spell-checking system.

Furthermore, if you are using an old version of Outlook, it could be causing issues too, and needs an upgrade.

To ensure that your emails are typo-free and errorless, double-check all these causes before sending them across.

How to repair the Microsoft Outlook spell checker?

By troubleshooting the issue, you can get your emails back to errorless form.

1: Restart Outlook

You may need to restart Outlook to make sure your changes take effect.

Before doing so, be sure to save all open documents and drafts. This is an important step that should not be overlooked as it will help ensure that no data is lost when the program is restarted.

Restarting Outlook can often resolve issues with spell checkers, especially if you have made any recent changes to the settings or installed a new version of the software.




To restart Outlook, you must first close it completely.

On Windows PCs, this can be done by accessing the Task Manager and clicking ‘End Task’ for Outlook in the list of running programs. If using a Mac, select ‘Force Quit’ from the Apple menu at the top left corner of your screen and then select ‘Outlook’ from the list of applications shown there.

Once closed, open up Outlook once more and see if this has resolved your issue with spell checking.

If after restarting Outlook you are still having trouble with the spell checker, then there may be a deeper issue at hand that requires further investigation for resolution. 

2: Is automatic checking of outgoing emails activated?

Verifying automatic checking of outgoing emails is essential to ensure accuracy.




To do this, follow these steps in Outlook:

  1. Access the “File” tab and launch the “Options” menu.
  2. Select the “Mail” tab.
  3. Check the box labeled “Always check spelling before sending.”
  4. Make sure to deselect the option for ignoring the original message text in reply or forward if it is already set.

This will help Outlook to properly spell-check each outgoing email you send. If all settings are correctly configured, then you can be confident that your messages won’t contain any typos or misspellings when they arrive at their destination.

Automatic spell checking is an important feature that helps maintain the accuracy of your communications. So, make sure you double-check these settings!

3: Change the language for spell check

Changing the language for spell-checking is a great way to ensure your emails are accurate.

To do this in Outlook, open the “Review” tab and click on “Language”.

Select “Set Proofing Language” to view current language settings for spell and grammar checks.

Once you have chosen the desired language, test it by pressing the “Spelling & Grammar” button in the same tab.

This will launch a small dialog window which should display the correct language.

Make sure to uncheck “Detect Language Automatically” if it is already checked as this can cause issues with foreign words.

This easy adjustment should guarantee that all of your emails are free from spelling errors and typos.

4: Is the spell checker correctly activated?

To ensure spell check is working properly, it’s important to check the settings for Outlook AutoCorrect.




Follow these steps:

  • Go to the “File” tab
  • Click on “Options” in the left-hand menu
  • Switch to “Mail” in the pop-up window
  • Select “Spelling and AutoCorrect”

Under “When correcting spelling in Outlook”, make sure both boxes next to “Check spelling as you type” and “Mark grammar errors as you type” are checked.

If these options aren’t active, spell check will not be running in Outlook.

5: Check installation and update status

Make sure your operating system and Office package are up to date so you can start using Outlook correctly.

Check the following items to make sure everything is in order:

  1. Is the operating system up-to-date? Have you installed any recent updates?
  2. Is Microsoft Office, including Outlook, installed properly?
  3. Are all components of the Office package updated with the latest versions?
  4. Does Outlook have all its features enabled and working correctly?

To ensure that your Outlook experience is efficient and error-free, double-check that you have a valid license key for installation, uninstall it completely from your device if necessary, and then reinstall it properly according to Microsoft’s instructions.

6. Enable Proofreading at Template Level Using Language Options

Enabling proofreading at the template level is a great way to ensure accuracy in emails. To do this, follow these steps:

  1. Open a new email.
  2. Click ‘Review’ > ‘Language’.
  3. From the language menu, select ‘Proofing Language’.
  4. Uncheck ‘Do Not Check Spelling or Grammar’.
  5. Click ‘Set as Default’.

For Outlook 2007, the process is slightly different:

  1. Select Mail Message from the New menu.
  2. Uncheck ‘Do Not Check Spelling or Grammar’ under Set Language.

7: Manually Check for Spelling and Grammar

You can quickly double-check your spelling and grammar before sending it in Outlook by using the F7 shortcut key. 

This is a simple way to ensure that your emails are error-free and look professional.

You can also move to the Review tab in the menu bar and select Spelling & Grammar, which will let you manually check for any errors.

In Outlook 2019, 2016, 2013, and 2010, you can enable this feature permanently by going into File > Options > Mail > Always check spelling before sending.

For Outlook 2007 users, click Tools then Options, and select Always Check Spelling Before Sending from the Spelling tab.

After making this selection, make sure to hit OK so that it saves your settings.
