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

More info: While we’re focused on remediation, users and admins may be able to create allow rules to prevent email messages from Gmail senders from going to the junk folder.<\/p>\n

Current status: We reverted to our previous ML model; however, some impact persists. We’ve initiated deployment of an additional ML fix to update the data set for identifying spam, which we anticipate will remediate the remaining impact. Once the deployment completes, we’ll monitor our telemetry to ensure the email messages are no longer marked as spam.<\/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 processes, which safeguard 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
