Users and user groups

Resource Limit
Users 3,000 per organization
User groups 1,000 per organization

Each organization, such as a partner account or customer account, can have up to 3,000 users. Each organization can also have up to 700 user groups.

For example, assume you have a partner account with ten customer accounts. Each customer can have up to 3,000 users. The partner account itself can also have up to 3,000 users. In total, the partner account and its customer accounts in this example can have up to 33,000 users. In other words, the limitation is not cumulative across multiple accounts. Rather, it is limited per organization.
