We are seeing significant progress with the fix rolled out by Microsoft for their issue impacting the sending of emails with large attachments via the Graph API using multipart/form-data. Over the past 48 hours, the error rate has dropped substantially, and we are monitoring the improvements closely.
- US Region: The error rate has decreased to 0.047% over the past 24 hours.
- EU Region: The error rate has decreased to 0.060% over the same period.
We will continue to monitor the situation and provide updates as needed. Thank you for your patience as Microsoft works to fully deploy the fix.
