High CPU usage when typing a message in Outlook

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...

    Dear Linda,

    Thank you for your message.

    What we can confirm is that the problem only occurs on Win 11 Pro platforms.
    There is no problem when running on Win 10 Pro OS;
    Strangely enough, the problem only affects Outlook ; running WORD 2K16 on Win 11 OS does not cause any issue (although WORD and OUTLOOK share the same kernel).

    Does Outlook 2021 suffer from the same High CPU usage problem, when running on Win 11 ?

    Thank you for your consideration.
