Access Mail Merge to Word Error

[DanSans54]

When I run mail merge to send addresses to Word the Mail Merge Wizard gives the following error: The ShowMe command is not available in Word.

I've tried multiple Word files, I've tried it on a different computer, I've chatted with Office 365 help desk and even created a new database and still have the same issue.

The mail merging process generally requires the following steps:
Creating a main document and the template.
Creating a data source.
Defining the merge fields in the main document.
Merging the data with the main document.
Saving/exporting.
