In July 2025, Microsoft introduced an update to OneDrive that allows users with both Personal and Business accounts to synchronize their data. This new feature has raised concerns among IT professionals about potential security risks related to data leakage and privacy issues. The introduction of this function could make it easier for employees to inadvertently bypass company security policies when they use personal OneDrive accounts on business devices, potentially leading to the exposure of sensitive corporate information.
According to a recent article from TechZine.eu, Microsoft’s new feature named “Prompt to Add Personal Account to OneDrive Sync” enables users with both personal and business OneDrive accounts to synchronize data without additional configuration. This could be problematic if employees do not understand the security risks involved in such an action. The function was initially set to roll out in June 2025 but started its deployment in July 2025.
Administrators can mitigate these potential issues by setting up specific group policies that prevent personal accounts from being used on company devices or disable the synchronization prompt entirely. These actions require awareness and proactive measures from IT teams to ensure corporate data remains secure and compliant with relevant regulations.
While Microsoft provides options for administrators to control access to OneDrive Personal within a business environment, many small companies may overlook these settings due to limited IT resources or lack of expertise in cloud administration. This could expose businesses to significant risks without them even realizing it.
