Use Microsoft Teams scoped directory search
Microsoft Teams scoped directory search allows organizations to create virtual boundaries that control how users can find and communicate with other users in their organization.
Microsoft Teams lets organizations provide custom views of the directory to their users. Microsoft Teams uses Information Barrier policies to support these custom views. Once the policies are enabled, the results returned by searches for other users (for example, to initiate a chat or to add members to a team) will be scoped according to the configured policies. Users will not be able to search or discover teams when scoped search is in effect.
In Exchange hybrid environments, this feature only works with Exchange Online mailboxes, and not with on-premises mailboxes.
When should you use scoped directory searches?
Scenarios that benefit from scoped directory searches are similar to address book policy scenarios. For example, you may want to use scoped directory search in the following situations:
- Your organization has multiple companies within its tenant that you want to keep separate.
- Your school wants to limit chats between faculty and students.
To learn how to use address book policies, read Information Barrier policies in Exchange Online.
Address book policies provide only a virtual separation of users from directory perspective. Users can still initiate communications with others by providing complete email addresses. It is also important to note that any user data that had already been cached, prior to the enforcement of new or updated address book policies, will remain available to users for up to 30 days.
Turn on scoped directory search
Use Information Barrier policies to configure your organization into virtual subgroups. For more information, see Define Information Barrier policies.
In the Microsoft Teams admin center, select Org-wide settings > Teams settings.
Under Search, next to Scope directory search in Teams using an Exchange address book policy (ABP), turn the toggle On.
This change can take a few hours to replicate.
