Latest Message<\/th>\nTitle: Admins may be unable to perform actions involving Domain Name System (DNS) records within the Exchange admin center<\/p>\n

User impact: Admins may be unable to perform actions involving DNS records within the Exchange admin center.<\/p>\n

More info: This issue may impact admins attempting to perform any actions involving DNS records within the Exchange admin center, such as provisioning new domains or mailboxes, accessing the Exchange admin center, or changing domains from IPv6 to IPv4. <\/p>\n

Current status: We\u2019re progressing with our efforts to disable the provisioning feature responsible for generating additional synchronization divergences and are continuing cleanup efforts to remove the existing backlog. In parallel, we\u2019re implementing processing changes to help reduce system load and improve throughput, as we work to restore affected provisioning operations to expected service levels.<\/p>\n

Scope of impact: Admins attempting to perform actions involving DNS records within the Exchange admin center may be impacted. This information may be updated as our investigation continues.<\/p>\n

Start time: Wednesday, June 17, 2026, at 6:00 AM UTC<\/p>\n

Root cause: A recently enabled provisioning feature introduced a large number of synchronization divergences, resulting in repeated cmdlet executions that’s causing resource contention and impact.<\/p>\n
