Latest Message<\/th>\nTitle: Some users\u2019 inbound email messages sent from Gmail accounts may be incorrectly marked as spam and quarantined<\/p>\n

User impact: Users\u2019 inbound email messages sent from Gmail accounts may be incorrectly marked as spam and quarantined.<\/p>\n

Current status: We’re reverting to our previous ML model, and we’re monitoring for mitigation as we rollback the model for all users. We aim to provide a timeline to mitigation as one becomes available.<\/p>\n

Scope of impact: Some users that are expecting to receive email messages sent from Gmail domains in their Exchange Online inbox may be affected by this issue.<\/p>\n

Start time: Saturday, April 26, 2025, at 12:00 AM UTC<\/p>\n

Root cause: Our ML model, which safeguards Exchange Online against risky email messages, is incorrectly identifying legitimate email messages as spam due to their similarity to email messages used in spam attacks, which is resulting in impact.<\/p>\n
