Issue Status: ONGOING

Issue Description: Users’ files uploaded to Microsoft Teams channels may be incorrectly hosted on the users’ OneDrive for Business.

More info: Sent previews may appear blank after pasting images into Microsoft Teams chats.

Current Update: 20/12/2024 11:00:00 AM – Microsoft validations of the fix are ongoing to ensure its efficacy in mitigating impact, and they continue to expect that the deployment will start by Monday, January 6, 2025.

Scope of impact: Impact is specific to some users who are served through the affected infrastructure attempting to view previews of sent images from the Microsoft Teams desktop app.

Root cause: A recent update, intended to enable a feature focused on improving image handling in Microsoft Teams chats, inadvertently introduced a code regression causing images to not be checked for successful upload status” before being sent.
