Minimum versions for sensitivity labels in Office apps
The capabilities tables on this page supplement Manage sensitivity labels in Office apps by listing the minimum Office version that introduced specific capabilities for sensitivity labels built in to Office apps, or if the label capability is in public preview or not available.
New versions of Office apps are made available at different times for different update channels. For Windows, you'll get the new capabilities earlier when you're on the Current Channel or Monthly Enterprise Channel, rather than Semi-Annual Enterprise Channel. The minimum version numbers can also be different from one update channel to the next. For more information, see Overview of update channels for Microsoft 365 Apps and Update history for Microsoft 365 Apps.
New capabilities that are in private preview aren't included in the tables but you might be able to join these previews by nominating your organization for the Microsoft Information Protection private preview program.
Tip
When you compare the minimum versions in the tables with the versions you have, remember the common practice of release versions to omit leading zeros.
For example, you have version 4.2128.0 and read that 4.7.1+ is the minimum version. For easier comparison, read 4.7.1 (no leading zeros) as 4.0007.1 (and not 4.** 7000**.1). Your version of 4.2128.0 is higher than 4.0007.1; so, your version is supported.
The numbers listed are the minimum Office application versions required for each capability.
Note
For Windows and the Semi-Annual Enterprise Channel, the minimum supported version numbers might not yet be released. Learn more.
