Description
Users may see legitimate .docx email attachments mistakenly marked as malware and may be unable to open attachments. Only .docx file types are affected. Microsoft's investigation shows that a recent update inadvertently caused an .XML file present in Word documents to be marked as malware which is causing the issue. They are reverting the update and reprocessing the messages to ensure that all affected messages and future emails are resolved.
