For the PowerShell Mail integration with Microsoft Exchange service account when only iOS and Android devices are in use, the minimum requirements include the Mail Recipients role and the Organization Client Access role. The Mail Recipients role is essential for managing email recipients, and the Organization Client Access role is necessary for accessing the client connections. These two roles provide the required permissions for managing iOS and Android devices. Recipient Policies role is not needed unless managing Windows Phone 7 and BlackBerry devices, and PowerShell 2.0 is outdated and not specific to the roles required.

The content gateway-related log files on the Unified Access Gateway (UAG) are stored in the /opt/vmware/gateway/logs directory. This directory is designated for log storage related to various gateway operations on the UAG, ensuring that administrators can easily access and review log files for troubleshooting and monitoring purposes.

To troubleshoot a device, the most appropriate console location is 'Monitor > Reports and Analytics > Events > Device Events'. This path specifically includes 'Device Events', highlighting it as the relevant section for viewing events related to devices. This allows for focused troubleshooting based on device-specific logs and events, making it easier to identify and resolve issues with the device in question.

After troubleshooting, log levels in systems like Workspace ONE UEM are typically set back to a less detailed level to conserve resources and avoid excessive logging. 'Severe' generally captures only the most critical issues, which is appropriate when detailed logging is no longer needed. 'Error' might still log too much unnecessary information. 'None' would disable all logging, which is not advisable for ongoing operations.
