One of my systems (out of four) that all have recently ( about 3 weeks back) been completely reloaded for Office 365 including a full run of the MS uninstaller app first, now has a feature that many people have asked for but MS has yet to restore. On this one system spellcheck works in a way I have never seen and I would LOVE to get the same functionality onto the other systems if possible.

In our office, ONE other person out of 30 also seems to have lucked out and gotten the same setup but no one else has.
This is Office 365 Business installing the 2016 App package. All users have the same option which is Office Insider Slow.
Ver. 1610 build 7466.2023. The spellcheck feature I am seeing like this is in the desktop software not the Cloud version.

On the one "special" copy Spellcheck has become a much More useful and handy option. Any misspelled word is underlined in the usual red squiggly line but after that, right clicking it brings up many new options to correct.

It has the usual suggested correct spellings - but - now each of them is accompanied by a short dictionary-like definition of the word when spelled that way. PLUS they each have another black arrow that if clicked offers to read the word aloud and more important offers to make that spelling of the word into an Auto-correct option.. Right There!. No need to jump through all the usual hoops to get it added.

This same 'feature' also works in Word and all the other Office Desktop Apps on that one system. I have tried to check everything i can find that would indicate any new or different version of anything but cannot find a single change that is different between it and the other three systems my email address is licensed on. Nor can i find anything in Windows 10 configs that is different.

I have nothing in common with the one other person who also somehow ended up with this new setup either.

This actions look a little like a grammar check but isn't. Words that are spelled correctly but are not the right word for the sentence as used are underlined in a double blue line which can be clicked to get the same options along with their definitions. I have asked in several MS forums about this but gotten no replies to answer the mystery. I did run across a few posts from people asking MS to restore the option for adding the "auto correct" direct from the right click on the misspelled word as it used to be. Also a statement from MS that this was a planned FIX to happen this year.

I dont want to scrub too deeply on the one system as i am afraid this new feature will stop working and I dont want to lose it.

If anyone else has seen this and knows what it is or how to control it I would surely like to know how to activate it on my other 3 systems.
