Azure IoT Central limits the number of applications you can deploy in a subscription to 100. However, there is no specific limit on the number of Microsoft account users that can be added to a single Azure IoT Central application. Please see IoT Central limits for more details.

The following limitations apply to Microsoft Entra groups and service principals:

• Total number of Microsoft Entra groups for each IoT Central application can't be more than 20.
• Total number of unique Microsoft Entra groups from the same Microsoft Entra tenant can't be more than 200 across all IoT Central applications.
• Service principals that are part of a Microsoft Entra group aren't automatically granted access to the application. The service principals must be added explicitly.

In addition to the restrictions on the users, IoT Central organizations to which users can be associated with, has the following restrictions.

• The hierarchy of sub level organizations can't be more than five levels deep.
• The total number of organizations can't be more than 200. Each node in the hierarchy counts as an organization.

As long as these requirements are met, we should not have any issues adding additional users to the IoT Central application.

Also, please see Manage users and roles in your IoT Central application and Frequently asked questions for IoT Central for more details.

I hope this helps. Do let me know if that helps or have any other queries.
