You can check compatibility between versions of your Microsoft 365 files to see if features in a file are supported by older versions of Microsoft 365 by using Compatibility Checker.

To check compatibility with an older version of Office

  1. Click the File tab, and then click Info.

  2. Click Check for Issues, and then click Check Compatibility.

    In Visio 2016, on the Info tab, click Check Compatibility.

Any issues between the versions are listed under Summary in the Compatibility Checker window.

Note: Selecting Check compatibility when saving documents in the Compatibility Checker window causes the Microsoft 365 application to automatically check for compatibility issues when you save your file as an earlier version.

To save your file in an earlier Microsoft 365 format, see Save a file.
