Hello,
I am using Office 365 University Edition on Windows 7 OS.
Within a document there was a misspelled Word that was not red underlined by Word. As I was troubleshooting with a technician we can to the conclusion that text within a Word document originated from a copy and paste from a PDF bypasses Word's spell checker since a PDF file is essentially an image of the document converted.
Additionally, if that same misspelled word was manually typed into another paragraph (still misspelled) within the same Word document, Word would not red underline that instance either. If I was to copy the misspelled word into Notepad (presumably to remove all formatting) and paste it back into the same document, Word still would not red underline the misspelled word.
However, if I was to copy that selection into notepad and then copy and paste it back into a fresh Word document, Word would function as normal and flag the misspelled Word.
It appears to me that by copying content from a PDF and pasting it into a document, the PDF content overrides the ENTIRE document's ability to accurately spellcheck.
The word in question was "workth"; a misspelling of the word "worth". Default language for my OS and for Word is set to English.
It is my hope that a solution to this is possible and viable and would be addressed in future updates or editions of Word.
Thank you.
