Latest Message<\/th>\nTitle: Users may encounter failures when sending or receiving email messages protected by Information Rights Management (IRM)<\/p>\n

User impact: Users may encounter failures when sending or receiving IRM protected email messages in Exchange Online.<\/p>\n

More info: Users sending IRM protected email messages receive a Non-Delivery Report (NDR) containing an error stating “554 5.6.0 Corrupt message content”.<\/p>\n

Current status: We’ve developed and subsequently deployed the aforementioned potential fix and are monitoring the affected service environment while reaching out to some affected users for testing to ensure that it has the desired results and to determine whether any additional mitigating actions are required.<\/p>\n

Scope of impact: Any user serviced by the impacted portion of infrastructure sending or receiving IRM protected email in Exchange Online may be affected.<\/p>\n
