Latest Message<\/th>\nTitle: Admins can\u2019t upgrade groups from distributions lists to unified groups from PowerShell and the Exchange admin center<\/p>\n

User impact: Admins can\u2019t upgrade groups from distributions lists to unified groups from PowerShell and the Exchange admin center.<\/p>\n

Current status: We\u2019re proceeding to work on the fix to ensure directory cache information is refreshed correctly across all servers. We\u2019re also progressing our deployment validation and now expect to provide a completion timeline by our next scheduled update. <\/p>\n

Scope of impact: Impact is specific to some admins attempting to upgrade groups from distributions lists to unified groups from PowerShell and the Exchange admin center. This section may be updated as our investigation continues.<\/p>\n

Root cause: A timing-related issue during group creation across backend systems where service requests are processed before directory information has fully refreshed across all servers, leading to impact.<\/p>\n
