Add additional Spell Check languages to Outlook on the Web (Exchange, Office 365 and Outlook.com)

Outlook on the Web (formerly known as Outlook Web App or OWA) completely relies on the spellcheck capabilities of the Internet Browser that you are using.

For some browsers, it is quite easy to add additional spell-check languages while for others you need to dig a little bit deeper within the options and settings that the browser provides.

Internet Explorer and Edge

Internet Explorer 10, Internet Explorer 11 and Edge completely depend on Windows to offer you spell check capabilities.

By default, Windows only offers you spell check capabilities for the language that you chose to install Windows in, but luckily it is quite easy to add additional languages in the following way;

• Windows 10
  Start-> Settings-> Time & language-> Region & language-> Add a language
• Windows 8
  Control Panel-> Clock, Language, and Region-> Language-> Add a language
• Windows 7
  In Internet Explorer: Gears menu-> Manage Add-ons-> Spelling Correction

In Windows 7, you can do this via the right click menu on a misspelled word.

Toggle between languages with Windows + Spacebar.
