External Group and Group Membership Limits in Microsoft Search
Raytion connectors reflect the custom security model of the source system in Microsoft Search. In order to do so, the connector creates external groups, which correspond to the groups from the source system.
The connector also links Microsoft Search users, i.e., users in Azure AD, to the correct external groups. This way, early-binding security trimming works.
External Groups Limit
However, there is a limit regarding the synchronization of external groups: All Microsoft Graph Connectors within a tenant can create up to 100,000 external groups. If this threshold is reached in your tenant, please contact the Microsoft support and check if they can extend the limit.
