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’ve encountered an issue preventing us from safely rolling out the code changes we were previously theorizing may be able to resolve the issue. We’ve identified that due to the complexity of the involved request flow and low volume of data associated with the impacted scenario, our internal reproduction of the issue is insufficient to conclusively validate our root cause theory without making changes to enhance our service logging specific to this scenario. We’re evaluating options for implementing advanced logging and data collection methods to assist us in identifying our next steps towards remediation, as well as reassessing our options for safely deploying our potential fix.<\/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
