A family of Microsoft word processing software products for creating web, email, and print documents.
Hi NF_29,
We appreciate that you posted back and confirmed the scenario with us, we also appreciate that you spent your precious time doing those tests.
We read your description, and it seems that five users have the same problem and only Word application has this problem. Word Online doesn’t have this problem.
If so, according to your tests, since this issue only occurs on Word on multiple computers, this issue may be related to your Word client.
Since our category focus on Office 365 business product, and you are using Microsoft Office professional Plus 2016, due to the limited resource, we may not use Word professional Plus 2016 to test it on our side. Given this situation, we do understand the inconvenience caused and apologize for it.
The best way to troubleshoot the issue is to report the issue to the related Team. We’d suggest you contact your office 365 administrator to go to Office 365 Admin Center-> Support-> New Service Request, the support engineers there have the correct escalation channel and this is the most efficient way to report such issue. You can refer to this article to check the way how to raise a ticket. Ways to contact support for business products - Admin Help. And the engineers in related team have enough resource and environment to help you test.
At the same time, you can also go to Microsoft Q & A forum to post a new thread, which is specific channel to handle Microsoft Office professional Plus 2016 related questions.
Thank you for your patience so far.
Best Regards,
Sukie
