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: Some users may encounter delivery delays of up to approximately four hours. The issue isn’t client-specific, thus this impact may occur in all Exchange Online connection methods.<\/p>\n

Current status: We’ve deployed the revised fix but identified that this has only improved delays for some users and hasn’t provided the expected relief for all users. We’re assessing options of disabling the free\/busy publishing assistant to prevent CFMs from being generated and causing email delivery delays. This will restore email delays but users may still see outdated free\/busy information in Exchange Online. After disabling the assistant, we’ll deploy a longer term fix to enable the assistant without causing an excessive load of CFMs.<\/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
