High CPU for multiple processes Microsoft 365

Question

In the last several days I have noticed my laptop CPU fan blowing constantly. The culprit seems to be 4 identical processes using the same amount of CPU as each other continuously hovering at about 8-12%. This keeps the fan blowing 24/7.

The Task Manager shows the Process name as "Microsoft 365 and Office (32 bit)" and no Office applications are running. When I view the details the executable names are "odt____.tmp.exe" with the underscores representing some 3- 4-character hex value, e.g. C67A.

I can end the tasks but they come back after a time and the CPU fan turns on again.

What are these processes and can I turn them off?

TIA

BTW, I tried to include a screenshot, but the image upload doesn't work.

Answer 1

I also have this same issue on multiple computers. I noticed that when restarting the computer the processes go away although they then come back after some time. These processes take up quite a lot of cpu usage and in turn make the computer fan activate at a high speed. Would love to know the resolution to this issue.

Answer 2

I have the same problem for several days. Even after deleting the files they come back and go to 25% CPU usage (100% on 1 core).

I updated 365 but no difference.

Answer 3

Our only way to stop so far was to disable the push of the package through our MDM. It does not uninstall it just stops trying to push it. It is not Intune but same general thought process.

Answer 4

In my case, though we do not use Intune we are using a different MDM which uses Choco and I traced it back to setup.exe (one from November that keeps showing back up after deleting so MDM related) in a folder under c:\windows\temp. We do not see ofdeploy running. But big picture this seems to be an instance of O365 for business continuing trying to reinstall/update. I just opened a ticket with MS so one more person reports it. I am afraid the only way to stop it is to stop our MDM from pushing.

Answer 5

I'm seeing the same thing. 2-4 processes, each consuming ~12% CPU. The files are living in C:\Windows\Temp. I can delete those (with seemingly no impact to functionality) but they will return after a reboot.

EDIT: One of these processes returned before a restart.
