Message Summary
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.
Configure and manage sensitivity labels in the Microsoft Purview compliance portal.
