High CPU for multiple processes Microsoft 365

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.

    Magically, the process creation has ceased today. It stopped occurring after todays quality updates. (i'm in the test ring using Autopatch) I searched for an update that would have anything to do with office deployment tool but nothing stood out. I am just so glad my CPU has returned to normal and no more odt<Random>tmp.exe files are being generated.

    I think you're right. Mine stopped yesterday and I was trying to figure out what might have fixed it since I applied those Windows Updates and also updated Office to the newest release (Version 2312 Build 16.0.17126.20132) 64-bit and those rogue processes seemed to have finally stopped...fingers crossed.

    MS Support has told me that any support tickets need to be opened with their MDM department, not Intunes or Office. Our testing has shown it is the MDM checking to push updates that is causing this.

    Our fleet of devices automatically update BIOS every time an update is released and this hasn't helped us. So far, we've had success with two of the previously mentioned approaches:-

    • sfc /scannow or
    • remove odtxxxx.tmp.exe files from C:\Windows\Temp

    We're waiting to see if either or both approaches are permanent of if the problem may resume, possibly as patch management or MDM tries to push further Office updates.
