word to adobe export without comments?

we just started our Adobe Acrobat Pro DC subscription 2 month ago and we have following (for us big) issue:

we have +99 Word (version 2016 )documents and we need to merge them into different Pdfs (for creation of technical manuals) so the merge function itself works fine.

But we dont find any option of disabling that the comments are NOT part of the PDF.

So in the +99 word files are (internal) comments about version control, editor notes etc.

But in the PDF will be a customer Document so they are not allowed to appear.

and we tryed everywhere but we dont find these solution of this issue.

the only 2 thinks how work are:

- delete all internal comments (really bad, because you need to create a extra copy and hold booth word files uptodate)

- create a pdf via the word print function - choose adobe pdf printer (without markup) and save it (more bad because the quality is poor! and we need to create often new versions of manuals so we need a lot of "manual work" for each word document....

so anywhere a suggestion?

thanks,

Timon
