What is Outlook spell check?
The proofing tool in Outlook checks the spelling of your emails and flags spelling and grammatical errors. It works in a similar manner to the spell checker in Microsoft Word and alerts you to errors as you type.
You can enable spell check in Outlook so that emails are automatically checked for errors before sending. You’ll receive a notification when an error is made and thus can avoid accidentally sending emails with mistakes. It’s important to correct spelling mistakes before sending them because retrieving sent emails in Outlook is rarely possible. The spell checker includes suggestions for solutions and the correct spelling of words and sentences. The tool alerts you in case of missing or incorrect punctuation marks or repeated words.
Depending on the recipient and type of email, you could add smileys in Outlook emails to loosen up your communication.

How to enable manual spell check in Outlook
Irritated by the red and blue marks of misspelled words and sentences? You can quickly deactivate the automatic spell check as described above. This doesn’t mean that you need to forego spell checking. You can still use the manual spell checker, which works even after AutoCorrect is deactivated.
For this purpose, select the “Review” tab and click on “Spelling and Grammar” once you finish composing your email. The spell checker opens in a new dialog box and will suggest corrections for misspelled words or grammar errors. You can accept or reject suggestions and add your own corrections in the text field, or simply ignore them.
Outlook spell check: Set up proofing before sending
Don’t want to be disrupted by red or blue lines while writing but regularly forget to manually check the spelling of emails before sending them? Outlook has a solution for you too. The application now includes the option to auto-check your emails for errors just before sending them.
- Go to the “File” tab and click on “Options”.
- Select “Mail”.
- Activate “Always check spelling before sending” by adding a check mark. It’s a good idea to check the box next to “Ignore original message text in reply or forward”. This prevents notifications of errors in emails before sending.
- Now click on “Send” and Outlook will check the spelling of your message. If your email is free of errors, it will be sent immediately. If errors are discovered, you will receive a corresponding alert.
