We have an instance where an integration that accepts and processes and inbound email with .xlsx attachment. The attachment is being attached to the data source, but the .xlsx is being removed and the extension is now "originalfilename".xlsx.txt. Inside that .txt file it contains the text "This attachment was removed."
In the sys attachment table it shows that text file with the content type "text/plain". It looks the same way in the sys_email table. When we open the .xlsx file it looks fine. No special characters. This integration has been working fine for years. No change to the source job, no change to the servicenow inbound action etc.
Is there any way to troubleshoot this and find out what it is that servicenow does not like about the attachment? Is there any debug logging available at the email engine level? How can I log what it is that is removing the attachment?
We have narrowed this down during troubleshooting to know that it most likely isn't anything to do with the inbound action or associated script.
Thanks
