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.

    It's *possible* the latest update has fixed this behaviour for me?

    Given that you've got a nice test in an iso environment, I'd be interested to see if it's fixed for you Tourmalet38?

    Cheers

    Quick update for what it is worth: simply opening or closing Dropbox (latest version, 17.4.33) allows me to replicate the symptoms in an iso environment. Dropbox on = bad, dropbox off = good. 

    Settings in Word (markup on or off, spellchecking as you type on or off) did not make that much difference to the CPU overload compared to Dropbox. 

    I have unplugged Expandrive as well. It has been deactivated for a few weeks and it therefore not a part of the issue in this post. However, I mention it because much like Dropbox now, when I was running it, i also had the impression it was taking a lot of cpu power.

    I will repost to confirm these observations in 10 days or so.

    Great message board here: hosted by MS, apparently, but not staffed by it. Most (all?) folks are just volunteers.
