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.

    Hello,

    I am experiencing the same issue. Outlook is crashing every time I try to send an email - this happens even in safe mode. Sending from my iPhone works fine, it is only occurring on my laptop.

    I am not sure what to do.

    The way I have resolved this is by purchasing an Office 365 annual subscription and upgrading Outlook.

    This feels like I have been forced by Microsoft to upgrade my purchased version of the Outlook client.

    I didn't ask for the new version of 365 to be installed on machine earlier this week - it just happened.

    Hi Sola,

    Thankyou for the suggestions. I tried them all except creating a new profile.

    I still have the same issue. I now have log files from the online repair.

    I know that the problem started after I changed Outlook's ribbon back to the classic mode. The Office update updated this and I preferred Classic mode. I feel that I can change it back to how it was, the problem will go away. I can live this with solution for a while. Is it possible to know how to get rid of Classic Mode on the Ribbon for Outlook please?

    Same issue here.

    Outlook application has 2 hotmail.com (outlook.com) email accounts. In the last day I can no longer send emails, the application simply closes and (sometimes) restarts.

    Created a new mail profile with a single hotmail.com account. Problem persists.

    Ran online repair of Office suite. Problem persists.

    Incoming email is fine.

    Only affects sending/replying and also when I switch accounts in the "from" field when composing an email.

    Sending and receiving from mobile app or outlook.com website is working fine.

    There are at least 3 reports on this forum in the last day of the same issue.

    Outlook 2311 (Build 17029.20028)

    Windows 10 22H2 (OS Build 19045.3693)
