Latest Message<\/th>\nTitle: Some users may not receive One-Time Passcode (OTP) email messages for encrypted messages in Exchange Online<\/p>\n

User impact: Users may not receive OTP email messages for encrypted messages in Exchange Online<\/p>\n

More info: Impact only occurs for users that have a process configured to perform a Domain Name System (DNS) check on incoming email messages.<\/p>\n

Current status: We’ve corrected the DNS record configurations for the affected domain and are reaching out to a sample of affected users to confirm whether the impact is remediated.<\/p>\n

Scope of impact: Some users expecting to receive OTP email messages for encrypted email messages in Exchange Online may be impacted.<\/p>\n

Start time: Thursday, June 26, 2025, at 2:31 PM UTC<\/p>\n

Root cause: DNS records for the domain that provides OTP email messages to encrypted messages became misconfigured, which is causing impact.<\/p>\n
