Hi Guys, just to let you know that the final version of Office does not work properly and have 70-100% CPU issue as reported on numerous posts here. In my case, it's the WORD with which I have the issue with and no remedies posted here help. Please provide the fix as soon as possible, because this bug renders the new suite useless...

Hi,

To resolve this issue, is your installation of Office for Mac fully updated?

In any Office application go to the Help menu and choose Check for Updates to launch the Auto Update app. Let AutoUpdate install the updates and then restart your Mac.

Update us with results for further assistance.

I'm having the same issue on the same software versions.

It's a large document ~130 pages with a lot of tables. Typing and scrolling are both laggy and I'm frequently getting SBBOD when I change a style (e.g. set a highlighted section of text to bold takes ~5 secs).

CPU usage is <1% when Word is in the background, but bring it to the front and CPU is >50%. It jumps to 80-110% when typing or making changes.

I have the latest Word for Windows in a VM with a fraction of the resources allocated and am not seeing the same issues with this document. 

Changing to Draft view has sped up scrolling and improved typing lag somewhat, but the high CPU usage remains.

UPDATE: updating to the latest fast preview (15.31 161227) has fixed the lagginess, but still experiencing 40-50% CPU when typing. At least it's now usable.

    Have the same problem: CPU usage around 70% when scrolling through the word document, and over 100% when typing. I have spellcheck disabled, Word 15.26 (160910) and OSX Yosemite 10.10.5. 

    Makes Word completely unusable.  

    Any suggestions...?

    I regret the 15.26 update. with this version the CPU use is more than 74% even without spell check on.

    Tried following:

    1. Installed august 15.25 update : issue does not resolve.
    2. Restore the word app from Time Machine backup also does not help.
    3. Removed Office completely as per : https://support.office.com/en-us/article/Uninstall-Office-2016-for-Mac-eefa1199-5b58-43af-8a3d-b73dc1a8cae3

    then Install fresh copy of the office, and then install august 2016 update [version 15.25 (160817)]. at least able to work now with spell check on.

    the august update can be downloaded from 

    https://support.microsoft.com/en-us/kb/3179163

    Hope Microsoft could fix this. the spell check is must for a word, I don't know how one can work without making any errors.
