Request-based chat access for a guest user

concept australia Updated Sep 10, 2026 1 min read guest-user-chat-access-st.md

Request-based self-configured app chat access enables a guest user to start and import chats in a single ServiceNow® for Microsoft Teams instance.

Guest sharing is enabled by default in Microsoft Entra ID and in ServiceNow for Microsoft Teams. As a result, users can invite guests to teams and sites, and share files with guests without having to request assistance from the IT department.

Guests can take the following actions:

Initiate a chat with people from outside their organization.
Import their chat conversations with people from outside their organization.

For information about configuring access for guest users, see Guest access in Microsoft Teams.

Guest access configuration is applicable to the following tables in both IT Service Management integration with Microsoft Teams and HR Service Delivery integration with Microsoft Teams applications:

HR Core task (sn_hr_core_task)
HR Life events Case (sn_hr_le_case)
HR Core case (sn_hr_core_case)
Request Item (sc_req_item)
Task (sc_task)
Incident (incident)
Request (sc_request)
Change request (change_request)

The ServiceNow system admin can extend guest access to other tables.
