Other information:

As in PDF, all the topics not included in your TOC are excluded from DOCX output. This is by design because DOCX is treated as a print format. By definition, there is no place in print-style documents for topics that are not included in the TOC.

If you want to include information from topics not included in your TOC you need to use Help+Manual's conditional output features or alternative TOCs to make alternative content for the DOCX version.

Hyperlinks are supported in MS Word DOCX files.
