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.

    Similar issue here.

    On Windows 10, after automatic update of Outlook (Office 2016) to version 16.0.17029.20028 recently, the Send Email will crash silently (sometimes with automatic restart) under the following condition:

    1. Sending with the Default Account continued to work. Can a) Select "New Email", b) enter recipient and text and Send without obvious problem.
    2. Sending with a non-default account by selecting it in the "From" list will immediately crash Outlook without notice (takes about 5 seconds). I cannot find any crash report in the eventvwr. I have 3 alternate accounts, all imap/pop, and it does not matter which one I select.

    I repeat, only changing the Account in the "From" list will immediately crash the application, so no chance to even press a Send button later.

    I tried restarting Outlook and Windows, did not resolve the problem.

    I tried safe mode, which does not resolve the problem.

    I tried a repair which did not resolve the problem.

    Only reverting the Outlook (Office) version to  16.0.16924.20150
    C:\Program Files\Common Files\microsoft shared\ClickToRun\OfficeC2RClient.exe" /update user updatetoversion=16.0.16924.20150

    finally restored the previous version and the problem is resolved.

    To run OfficeC2RClient I started a command line prompt in admin mode. Note that the utility did not give me any output whether it was successful or not. Only after a while (or may be restarting Outlook) the installation of the desired version started.

    However I have to disable automatic updates (in the dialog "Office Account / Update Options") to avoid updating to the buggy version again, so this is not a good solution for long term.

    I would just like to add to this thread. I have the same issue, which I noticed only a few days ago.

    Running Outlook as part of Office Professional Plus 2019

    Version 2311 (Build 17029.20028)

    On Windows 10

    Receive Emails OK

    When I hit SEND on new emails or replies to emails - Outlook crashes and restarts. Email is lost.

    Web based and Mobile app work fine.

    I have Microsoft Office Home and Business 2019 edition and my Outlook for windows is doing the same thing when I try to send an email. Receiving emails is fine, only trying to send an email. This all started when Microsoft added the Outlook.com version to my desktop computer shortly before Thanksgiving. Thanks a lot to Microsoft to stop me from sending emails at Thanksgiving time!!!! Microsoft should and MUST correct this immediately. Forcing users to buy Microsoft 365 is NOT a good solution. What can I do?

    I have the same issue with live.com and have tried all the useless "fixes". Except now it wants to switch me from 2019 to 365. Ugh! And I have to dig up my Product Key or it will shut down in 5 days. Please fix this!!!
