A family of Microsoft word processing software products for creating web, email, and print documents.
I've had the same problem and its been huge setback because I use this feature daily for redlining and tracking changes in legal documents; sometimes with other people collaborating. Jessica S_14, I feel your pain. The notes below highlight the solution that worked for me. See also the link to the help article below that explains some of the more detailed steps for how to roll Word and Office 365 back to a prior version. I'm running Microsoft Office Professional Plus 2016, which is the version having the problem. [FWIW, a different set of computers is running the latest Microsoft 365, and the hover feature also disappeared from those computers as well (and we successfully rolled them back to the 2022 December 13 Version 2211 (Build 15831.20208, using the same procedure below.)] https://answers.microsoft.com/en-us/msoffice/forum/all/revert-to-a-previous-version-of-office-365/79138c95-80b4-48fb-bef7-08619af3593e
A Microsoft Support Ambassador (Afeez) has been helping me for the past few weeks and he's been great. Afeez provided the link to the article above.
First we tried reverting back to older versions of Microsoft/Office 365 (Current Channel).
This version below didn't restore the 'authors' feature when you hover over a redline change.
2023 February 14 Version 2301 (Build 16026.20200)
Next I tried this version, but it still didn't restore the hover feature.
2023 January 10 Version 2212 (Build 15928.20216)
As an aside, this is the "<Add>" line that was added (replaced an existing Add line of xml code) to the xml file that the setup.exe program needs to access. (see link to article).
<Add OfficeClientEdition="32" Channel="Current" Version="16.0.15928.20216">
I noticed that Windows 10 pushed out a new set up updates, so I installed the latest Windows 10 update
April 25, 2023—KB5025297 (OS Build 19045.2913) Preview
Windows 10, version 22H2, all editions
After I restarted and the Windows 10 updates finished, I opened Word up to check for changes. To my surprise, the hover feature came back! So at least on my computer, the 2023 January 10 Version 2212 (Build 15928.20216) Office 365 Current Channel software roll back definitely brought back the old hover feature in Word. Its not the new "Cards" feature that Microsoft 365 is pushing in the latest versions, its the old hover over feature we've all known and loved as part of Track Changes for so many years. Looks just like the example shown below in Stefan Blom's post.
I'm not able to tell if the Windows 10 update released April 25, 2023 is what fixed this or not. But the combination of this Windows 10 update, and rolling Word and Office 365 back to 2023 January 10 Version 2212 (Build 15928.20216) definitely brought back the old hover feature.
Remember to go into the Account setting in Word and disable future updates so the fix doesn't get overwritten by a future update. Microsoft definitely needs to get this feature fixed and preserve the classic hover over feature. Knowing who made edits and what date/time the edits were made is an essential feature.
I hope others are able to benefit from this.
Cheers!
