These commands from the command line convert from markdown to HTML and then HTML to ODT.
pandoc .\some-file.md -f markdown -t html -s -o .\some-file.html
pandoc .\some-file.html -f html -t odt -o .\some-file.odt
That allows us to preserve some of the markdown formatting when importing a markdown documents into Office 365 or Google Docs.
