If you’ve over used a trial install of Office you’ll find that it goes into a limited usage mode – basically making it so documents are read only and not editable.
- This is a very quick post to help some people out on installation problems with Office for Mac 2016. I was about to factory reset this stupid computer. Thanks so much!-1. I have changed computer name and Office activation went fine. All other solutions including those suggested by official Microsoft pages were pretty useless.
- I have encountered this activation windows pop up even after entering product keys and my Microsoft outlook email, I have activated office 2016 on 20 PCs and now its asking again to activate again. Will I loose these product keys that I have used? If I have to download new office 2016 and install then activate?

Office 2016 Activation Without Key
Having been on Microsoft Office 365 for a few months now, we started to notice that when users who had activated software on a PC were removed from Office 365, the software would go into 'grace period' and would continually notify the new user of the PC that there was a problem.
The steps below show how to reset the trial period for Office 2016. It is a similar process for Office 2013 and Office 365.
- Close any Office programs (Word, Excel etc)
- Open “Computer” and browse to
- Right-click on OSPPREARM.EXE and choose ‘Run as administrator’
- Now open up an Office program and you should find the activation period has been reset.
