High CPU usage when typing a message in Outlook

Hello again, dear other users suffering from Microsoft's Outlook bug,

there is another thread where a user complains about the same issue: https://answers.microsoft.com/en-us/msoffice/forum/all/why-does-my-laptop-fan-start-every-time-i-type-an/f5acb9da-1375-48fe-b118-9e05ef8c8044

Unfortunately, there is also no solution. It's really a pity with Microsoft. Maybe, it's time now to switch from Outlook to Thunderbird, because in fact, Outlook is unregarded and supportless and Microsoft does not care at all about bug reports. Why then pay for it?

Just to add to the list. I have noticed this also. I am running on a laptop. I run a 14900HX so my usage is not very high in percentage, but the CPU frequenty goes really high and I see my CPU temp going upto 95°C with a lot of fan noise.

I have version 2412 (Build 18324.20194). Everything was freshly installed in november as this is a new laptop. So no historic issue can be caried over.

I noticed that eventhough it is (slightly) elevated when outlook is open. When having the New message window open and active, it really goes up. When the window is not active, it seems to go back down.

I don't know it it's just a coincidence, but I currently also have massive GPU (not CPU) usage from Desktop Window Manager parallel to using Outlook. So now Outlook as well as DWM make my system very slow nearly always when I work something.

It doesn't totally solve the problem either. I'm seeing abnormally high cpu usage from OUTLOOK.EXE with one client using monthly enterprise channel of Office 365 on Windows Server 2016. However another client in the same configuration and channel does not.

Thank you, this would have been worth trying it, but I neither get text predictions in Outlook nor is there a setting to didable it.
