I have an Outlook add-in deployed that performs processing before sending emails. It’s working smoothly across various environments, including:
- All major browsers, including Safari
- Windows Outlook (new UI)
- New Outlook UI on Mac
However, I’m encountering an issue in the legacy UI on Mac where Outlook crashes under one specific condition: when both an inline attachment and a regular attachment are added to the email. All other cases work without issue in the legacy UI on Mac.
We are specifically seeing this issue on outlook 16.90, everything is working fine on 16.88.
Dump of the crash:

Looks like your issue is more related to Outlook development, please kindly understand that the Outlook tag here we mainly focus on general issues about Outlook desktop client. In order to better solve your problem, we will add "Office Development" tag.
