High CPU usage when typing a message in Outlook

Question

OS: Win 11 Pro

Office: 2016 Pro

Hi everyone,

CPU activity goes to 16-22% when typing a message in Outlook 2016 and returns to 1 % when typing stops.

Deactivating (all) add-ins and Graphic acceleration did not solve the issue.

Deactivating spell check options did not cure the problem either.

The problem seems to be specific to Win 11 and does not occur on Win 10 OS.

If anyone has any suggestion on how to solve this issue...

Answer 1

I'm not aware of way to open a formal complaint...

That's a good question. Because if you contact their customer support, they just endlessly let you try this and that and the same again, always assuming that you as the user would have misconfigured something and not Microsoft causes this bug.

Maybe the DSA (Digital services act) within the EU offers a possibility to force Microsoft to cover the issue?

Answer 2

Good point
Microsoft support is a waste of time.
I have support cases opened since May last year.
None of them has been properly addressed or resolved.

Answer 3

I have the same issue as described here. Everything is ok until start typing (new message or reply). Then CPU increases his activity to 10-20% for nothing! When stop typing, CPU activity goes down to normal.

I switched off all addons, no improvement...

Brand new notebook, Microsoft® Outlook® 2024 MSO (Version 2501 Build 16.0.18429.20132) 64 bit.

It's very annoying!

Answer 4

On occasion, merely opening an email prompts the fans of my device to activate. Once I start typing, the fans surge to their maximum speed. This incessant noise is profoundly irritating. I am perplexed as to why Microsoft continues to overlook such issues. I'm also using a brand new Windows 11 PC with i7-14700F 20 core processor, typing an email with Outlook should not be putting a load on this processor.

Answer 5

I worked with Microsoft support on this issue for a couple of months. Back and forth, back and forth, we tried everything. I even wiped a disk and reinstalled the OS, drivers, Office. I logged into several different computers that were known to be OK, and once my profile was added to outlook, that computer started having the issue too. So it appears to be account-related. Microsoft finally gave up and told me they wouldn't help any more. Here is the exact wording from the email:

We have checked with our engineering team, and it appears that this is likely a known issue. The engineering team is currently working on it, but there is no estimated time of arrival (ETA) for a resolution at this moment.

We have also been informed that several other users are experiencing the same issue.

Given the circumstances, I would like to ask for your closure on this case, as we do not have a resolution or an ETA for an update from our engineering team.

I didn't allow them to close the ticket, and asked several more questions, here are their answers to those question:

1. More Information: We are still investigating the root cause of the issue. It appears to be a known problem affecting multiple users.
2. Known Workarounds: At this time, there are no confirmed workarounds. Our engineering team is actively working on a resolution.
3. Affected Accounts/Installations: The issue seems to affect users across various accounts and installations, not limited to a specific group.
4. Windows 11 vs. Windows 10: The issue manifests on both Windows 11 and Windows 10.
5. Documentation: We have documented the issue internally, and it is being tracked by our engineering team. Unfortunately, there is no ETA for a resolution at this moment.

The MS support person again asked permission to close the ticket. I said absolutely not, but then I just got ghosted.
