Offic365 apps is loading the CPU

Vlad Olekhnovich 1

Hey there, y'all!

I have bunch of users, who stuck with high-loading of CPU, during editing of a document using O365's Word. I tried to google issue and found a few solutions, that worked for usual users, but not corporate one.

Here are some solutions that already were tried by users and specific of user's workflow:

Department members are using Collaborate mode to edit documents (so option "Use Office applications to sync Office files that I open" - need to be enabled - OneDrive's settings -> Office tab (as far as I understood, the option is required to use coworking mode);
Enabled "Tracker changes" function (department need to have Change tracker, since they are editing docs together);
Disabling of auto-save option in Word application didn't helped much;
Cleaning of cache of Office365 also didn't helped much;
I didn't try changing/deleting of Normal.dotm file (AppData\Roaming\Microsoft\Templates), since it may harm user's workflow (and won't help much, as far as I understood);
Disabling of "Spell check" didn't helped much.

Also, one of users noticed that OneDrive making copies too regularly. But in didn't found any settings related to it in OneDrive's client or setups in O365 Admin Centre (to provide its administrator with proper info).

So maybe anyone had deal with such issues or have any ideas about how to deal with loading of CPU.

Are you sure this is an issue with the Microsoft 365?
Have you checked the CPU in the task manager to see which processors are using a lot of resources.
Does it happens when the user is offline?

Could you please go to File > Account > Product Information, share us with the Office version number.
Please make sure Office is updaed to the latest.

Besides, does this issue just occur with co-authored files that store on OneDrive?
Or does this issue occure with all files no mater local files or personal OneDrive files that are not shared with oterhs?
I suggest you run Office apps in safe mode, and then open files for a test.
Safe mode could help us on identifying an add-in or extension that may be causing a problem on startup.

Any updates, you could post back.

Hey there! Sorry for long delay -- I been trying to get as full as possible input from users.

So! Office version (it updates centrally, so version is same for whole company):

Performance of the app is poor if Co-Authored mode is disabled, but file is on OneDrive. But if it stored locally, Co-Authored mode disabled and it doesn't syncs, then performance gets better.
Unfortunately, had no opportunity to check performance in Safe mode, but I checked Add-Ons of reporter remotely and there were nothing (at least, in the user's case, but she said situation should be same for others). But I have to notice that they are using custom templates.

Hi @Vlad Olekhnovich

Thanks for your shaing.

> But I have to notice that they are using custom templates.

Could you please let users test co-authring on a file that do not created via custom templates?

Besides, please check ｗhat features are used in their custom templates.

Hey! Happy Christmas and new year! Sorry that I kept this issue open for that long. End of the year was busy and users didn't give me any updates. But I noticed that performance got better after employees moved to newer and more powerful laptops. Thus, I think, issue was related to power of hardware. Yeah, it's kinda strange conclusion, but they cannot leave those custom templates or optimize their workflow in other way.

I really thankful, that you put you time into this issue and been giving me advices related to troubleshooting. Live long and prosper
