Outlook crashes when sending emails after Microsoft Update

Hi,

I had 2 updates today from Microsoft for Microsoft Office. I am using Windows 11.

"Microsoft Office Professional Plus 2016 - en-us" and "Microsoft 365 - en-us".

Versions for both are 16.0.17029.20028

This updated my Outlook client as well - I know this because it changed to a new menu bar. I changed this back to the classic outlook menu bar.

After this, my Outlook client crashes whenever I try to send an email.

I cannot revert to the new menu bar in case this is causing the issue as there is no option to do this.

I am still receiving emails.

There is a similar thread from earlier this year here: Outlook keeps crashing on email Send - Microsoft Community

If someone could kindly advise on this please. Thankyou.

    Same message, but should be a reply to this post ...

    For me the crash still occurs ... 

    Double check before I revert to a prior build for a different outlook version:

    I am on Microsoft Office Professional Plus 2019

    Outlook version 2311, build 17029.20028 click-to-run.

    Is this the correct version for me ? officec2rclient.exe /update user updatetoversion=16.0.16924.20124

    Thank you, Hettie_399

    So far, nothing has fixed this for me. I have uninstalled, reinstalled, removed all addins, recreated profiles, safe mode, repair, you name it. When I check updates, it says I am up to date, not sure where to get 17029.20052 -- and any "service" change didn't fix anything.

    This worked for me. Thanks!

    (Ignore the post before I edited this. I didn't notice that the "applying updates" was still running.)

    Hi all,

    I still repro the crash this morning even though the service change went through. I see some of you are using the workaround already. I'll post back when I have a status update.

    Workaround to revert to prior working build:

    1. Open a Command Prompt window (from Windows search box type Command Prompt, right click on Command Prompt and click Run as administrator)
    2. Paste the commands below into the Command Prompt window and press Enter after each:

    cd %programfiles%\Common Files\Microsoft Shared\ClickToRun

    officec2rclient.exe /update user updatetoversion=16.0.16924.20124
