Document and solution types monitored by telemetry in Office

Applies to: Office 365 ProPlus, Office 2019, and Office 2016


To assess your Office compatibility, we recommend using the Readiness Toolkit for Office add-ins and VBA. The Readiness Toolkit is a free download and can be used to identify the VBA macros and add-ins used in your organization. Also, the Excel-based readiness reports can tell you which add-ins are adopted or supported in Office 365 ProPlus and can provide suggestions on how to remediate VBA macros issues that are identified. For more information, see Use the Readiness Toolkit to assess application compatibility for Office 365 ProPlus.
