Latest Message<\/th>\nTitle: Users’ inbound and outbound email delivery may be delayed for 15 minutes or longer in Exchange Online<\/p>\n

User impact: Users’ inbound and outbound email delivery may be delayed for 15 minutes or longer in Exchange Online.<\/p>\n

More info: The issue isn’t client-specific, thus this impact may occur in all Exchange Online connection methods.<\/p>\n

Current status: During our review of the system logs, we identified that Control Flow Messages (CFMs) are still sending at an increased rate. We’re looking into options to prevent the additional CFMs in the affected portion of infrastructure, which we expect will mitigate the email delivery delays.<\/p>\n

Scope of impact: This issue may affect any user sending or receiving mail in Exchange Online.<\/p>\n

Start time: Monday, July 17, 2023, at 3:00 PM UTC<\/p>\n

Root cause: A recent code change related to our free\/busy publishing APIs has resulted in an influx of Control Flow Messages (CFMs), which are sent during certain free\/busy operations such as calendar replication, to be sent for other instances where CFMs are not necessary. This is resulting in a spike in messages on Exchange Online infrastructure, which is resulting in message queuing.<\/p>\n
