OFFICE 365 - ENABLING SPELL CHECK
Spell check is an application that flags words that may not be spelled correctly.
To enable spell check in Outlook 2016 Desktop Client:
- Select the File tab
- Click Options
- Click Mail
- If you want the spelling checker to run all at once when you click Send, select the Always check spelling before sending check box.
- To specify that the original text of a message not be checked for spelling when you reply to or forward the message, select the Ignore original message text in reply or forward check box.
NOTE: Spell check was removed from Outlook Web App in the 2013 version. When using OWA, you will need to rely on your browser's spell checker. Firefox, for example, automatically checks spelling; other browsers may require you to manually enable the application.
