Double-spacing won't save in .doc & .docx files

I am using MS Word v16.87 on Sonoma 14.5. I select the document content and change the line spacing to 2.0, then save the document as a .docx. Apple's Quick Look view of that document does not reflect the double spacing and it will appear single-spaced. That is also true for the same .docx content saved from Pages, or LibreOffice 24.2.5.

If you based the failure to double-space on the Quick Look view, I can assure you that the documents when opened in any of the above applications will retain their double-spaced text as originally saved.

You'll need to learn how to use styles in Word. Define a style for your content. I recommend creating a new style instead of trying to use or change the built-in styles. Create a paragraph style and set the line spacing to 2 lines.

As you add text, you will likely lose the styles with copy/paste etc. Don't worry about that. Don't try to fix it. It's easier to just select a paragraph and re-apply the style.

If you do this right, you'll have styles for content and all header levels. Then you can easily create a table of contents.

Try this again in a different login, unrelated to your current login, and not sharing any Microsoft 365 login or other details, and not whatever printer and Microsoft 365 printer driver you’re using.

Otherwise, take this up with Microsoft Support, and with school IT support. Their mess, and their requirement, respectively.

Tried creating your document in Apple Pages, and exporting to Microsoft 365 docx?

Anti-trust? Could you elaborate in that?

Again, have you tried creating the document using Apple Pages, and saved the Pages document as .docx?

It is your document. You can create it in any app you want to use, Pages, Word, LibreOffice, etc. then save it to whatever app you want such as Word. This is in no way "anti trust".

Yes. I can create a page with Pages, double space it, then export to .docx, and the .docx will NOT be double-spaced. Tried it, but no cigar.

You'll have to expand on what you mean by "no cigar". The procedure you describe seems to work fine and results in a double-spaced docx file.

Sounds like a question for the Microsoft Help Community.

But just looking at Word in the top menu there is a line spacing option that includes a double line spacing option.

How can I confirm,

Open it in Word.

If you don’t own word, take it to a friend who does.

I’ve never heard of a school that requires use of some software and doesn’t provide a license for it.
