Hello everybody,

In my current document, Word does not recognize mistakes in the spelling of words automatically, i.e. the words are not underlined. If I type F7, the misspelled word are recognized, though. When I open a new document, the spelling checker works flawlessly and underlines misspelled word immediately. Since my current document contains a lot of customized style settings, I do not want to change the document. Does anyone have an idea what my problem may be, and how I can solve it?

I'm using Office 365.

Best regards,
Sebastian
