This issue applies to MS Word 365 with Acrobat DC Pro Add-in.
Word version: Microsoft® Word for Microsoft 365 MSO (Version 2201 Build 16.0.14827.20158) 64-bit
Adobe Acrobat DC version: 2022.001.20117
Background story:
When the MS Word 365 Acrobat add-in is used to create a PDF (with create from headings selected in the Adobe preferences), bookmarks are created in the PDF output navigation panel as expected (refer to fig 3), but some of the headings do not link to their correct page when you click on them (they all default to page 1, top of the document). The affected styles are not MS Word headings as such but custom styles with MS Word paragraph Outline Level set to Level 1.
In contrast, if I use the MS Word Save as PDF, the custom outline level 1 styles again appear in the PDF output navigation bookmarks and they all link to their correct pages in the PDF output document.
Three support screen shot files are attached to aid this post as follows:
Fig 1. word-custom template-outline-structure.jpg (this shows the basic structure of the source MS Word document).
Fig 2. word-acrobat-addin-preferences-set.jpg (this shows the Acrobat addin prefrences set to headings).
Fig 3. pdf-output-from-word-acrobat-addin-save-as-pdf.jpg (this shows the pdf output created from the source MS Word document. The Outline 1 style are all those above ‘List of Acronyms’.
This triggers the question, how does Acrobat DC Pro recognize a MS Word 365 style as a heading and what determines how it automatically maps to the correct page. Is this a bug or a feature?
