Latest Message<\/th>\nTitle: Admins can\u2019t upgrade groups from Distributions Lists to Unified Groups using PowerShell or the Exchange admin center<\/p>\n

User impact: Admins can\u2019t upgrade groups from Distributions Lists to Unified Groups using PowerShell or the Exchange admin center.<\/p>\n

Current status: We\u2019ve deployed the fix to approximately 10% of the affected environment. We\u2019re investigating the cause of the deployment delay and exploring alternative approaches to accelerate the rollout.<\/p>\n

Scope of impact: Impact is specific to some admins attempting to upgrade groups from Distribution Lists to Unified Groups using PowerShell or the Exchange admin center. This section may be updated as our investigation continues.<\/p>\n

Start time: Friday, October 24, 2025, at 11:32 AM UTC<\/p>\n

Root cause: A timing issue during a recent migration is causing backend systems to act before directory changes are fully synchronized.<\/p>\n

Next update by: Friday, April 3, 2026, at 11:00 AM UTC<\/td>\n<\/tr>\n
