Microsoft Purview Information Protection: User-defined permissions support domain name restrictions

Coming soon to public preview and general availability, we’re updating the options for custom permissions, also referred to as user-defined permissions, to support domain name restrictions.

This message is associated with Microsoft 365 Roadmap ID 98131.

When this will happen:

Rollout to public preview will begin in mid-October and is expected to be complete by late-October.

Rollout to general availability will begin in early November and is expected to be complete by end of November. 

How this will affect your organization:

Within Microsoft Office files (Word, Excel, PowerPoint), when you choose a sensitivity label configured for user-defined permissions, you can now use domain names to restrict file access to specific individuals, or to all individuals from that domain. For example, you can specify “someone@example.com” or “@example.com” and permissions will be restricted based on those parameters.

What you need to do to prepare:

If you have previously configured user-defined permissions for your organization, no further action is needed to enable this feature.
