Microsoft Office 2016 does not support Equation editor 3.0.
I am Maths teacher. After installing Microsoft office 2016, since it does not support Equation editor 3.0, all equations cannot be viewed and edited. That means Maths teachers from all around the world cannot edit their notes any more. So I sincerely ask for your help to buy the license from Mathtype again. Thanks.
Thank you for your feedback. As noted in the Changes to Office 2016 article (https://technet.microsoft.com/enus/library/mt715497(v=office.16).aspx) Equation Editor 3.0 is no longer supported by Office. These objects can still be edited if you have the MathType plugin installed. We are aware of the issues with Equation Editor 3.0 and are considering potential mitigations, though as this equation editing is no longer supported we encourage you to use Microsoft’s builtin equation editing tools instead where possible.

So, does it mean that if I have MathType installed, I would be able to use Equation Editor the same way as in Office 2013 and earlier products? i.e. When I've opened a word file, select "insert" on the left and choose "object" on the right and I'll find a MathType selection on the list?

'These objects can still be edited if you have the MathType plugin installed.' Really, Word Product Team?! Have you actually attempted to use MathType with Word recently? Absolutely inexcusable product development.

Two possible solutions:
1. Stop using as much MS products as you can, it is definitely not worth of its price and struggle, rather contrary. E.g. LibreOffice work on Windows: https://www.libreoffice.org/
2. If you are unable to avoid MS office, use http://latex2png.com/, generate a picture and insert it to your document. Keep more complicated latex equations aside (e.g. in comment) if you would need to edit it. Basic introduction to math with latex:

Yet ANOTHER frustrated user! I'm looking to see if anyone with brains has been able to develop a plugin for this, or if it's worthwhile to switch to other software like GoogleDocs. Obviously, I will not be paying money for Microsoft products in the future!

but if how I need microsoft equation 3.0 for my dissertation paper?

bolso commented
yes that's a complete shamble, years of notes thrown in the loo, followed by MS word 2016, back to latex

I would be more willing to do this if Microsoft's builtin equation software wasn't sinfully ugly, and **** near entirely impossible to use.

This is a very late reply. It looks like Murray Sargent discussed this and possible workaround in some detail in his "Math in Office" blog: https://blogs.msdn.microsoft.com/murrays/2018/08/31/convertingmicrosoftequationeditorobjectstoofficemath/

Why not solving the problem? it is essential tool. Just bring it back and correct the mistake you (MS) made

Super frustrating....as a math teacher, I'm furious that I now have to redo equations with your equation editor 3.0. FIX THIS ISSUE!!!

Loreli commented
Microsoft's Equation Tool is seriously lacking and only uses a font that NO publisher on Earth uses. This is not acceptable in any way, shape, or form. I literally have thousands of documents with hundreds of thousands, if not millions of equations that are now unusable. Maybe the scientific and engineering community is a niche group, but, I would think that we are an important part of your business.

Acerbic commented
Hello. Can this be seriously the best approach to solve a 'security' issue? Would you apply the same stup*d standards for Office apps and builtin apps everytime you discover vulnerabilities? You guys are becoming the Ford motors in the industry. This is a botched update, fix it.

Nothing seems to work commented
Hi there Microsoft. I have tried all of the suggested workarounds (Install Math Type Plugin, Install MT Extra font) but still I cant view Equation Editor 3.0 objects. Hopefully a solutions is around the corner. Cheers

As another teacher I want to said that Microsoft Equation 3.0 was much better, but therewith the main reason to recover this editor is a very hard work in the thousands of documents accumulated for many years. The only answer of Microsft is we have to create again all these documents, it's another sign of its arrogance. Someone must declare Microsoft as an enemy of the Teaching and the University, and to report damages in a court.

Angry lecturer commented
I am a lecturer and a researcher. I have 20 years worth of lecture notes and scientific papers. As a matter of fact, I have just received two revisions to my latest submitted papers. I was given 2 weeks to submit the corrections  and guess whet? I cannot edit the original paper as the MS Equations are no longer supported. moreover, half of the equations cannot be viewed properly. Which means that in the two weeks instead of revising my papers to make them better I will have to retype every single one. Apart from the fact I cannot as the font does not match the journal template, neither the random equation formatting rules that one cannot change! I am really screwed and am urgently switching to Latex.
This is a major *****up where people are left completely helpless, hopeless and angry. Miscrosoft are already well known for doing this sort of thing, but for me this is a step too far where I lose the ability to use properly the entire output of my career as a result of one sneaky unnecessary update. Will consider switching to Linux altogether.

Frustrated Buyer commented
I am also a teacher, and after upgrading to mac os High Sierra my powerpoint began exhibiting many problems, and I bought the office 2016 for mac... Now I can't open my MS equations... this is incredibly unrespectiful... unbelievable that MS powerpoint simply can't at least convert automatically from one format to the newer! Frustrating! I hope an update for Office 2016 would provide a solution for this as soon as possible!

Margo commented
How do I use the the "Microsoft's builtin equation edition tools?" I don't want to just use one of your standard equations. I am a retired math teacher. How are teachers managing?

Kate Dodge commented
I am disappointed that Microsoft Equation 3.0 is not supported by Office 2016. Along with many others on this thread, I am also a math teacher and I have hundreds of documents using Microsoft Equation 3.0. The Office Equations is TERRIBLE! There are NO SHORTCUTS and so you have to click and use arrow keys to add in a simple exponent. In Microsoft Equation 3.0 all I needed to do was hit "control h" and it created an exponent. It takes two to three times as long to write an equation and it does not look half as nice as Microsoft Equation 3.0! Please, bring it back!

This is some visionary advice. It appears my workplace knew about this problem already two years ago. They pushed toward using google docs and Co. I thought very bad choice not even half as good as the Microsoft product. But at least I know it is bad. I am still reluctant to swap to any of the google things, but if this problem persists, it is probably good bye Microsoft, Hello Google  not sure if that is a good move, but perhaps that is what Microsoft wants. Let's go Google. NO, bring back equation editor 3.0. Just bring it back how hard can that be. As many posted I have so many documents that I cannot even look at the equations any more  this is out of this world. So irresponsible.
