# MS Teams - Professional Services with GDAP

## Professional Services with GDAP (Granular Delegated Admin Privileges)

## Goal

Assist customers with understanding the requirements for CallTower to access their Microsoft Tenant to perform Professional services.

## Summary

CallTower will perform MACD (Moves, Additions, Changes, or Deletions) requests for our non-CSP (Cloud Service Partner) customers for a professional service fee of $200 per hour, billed in 15-minute increments. You can find out more about the scope of support for your specific CSP type here: [Microsoft Teams Support Scope](/v1/docs/ms-teams-support-scope)

To access your tenant, we will need to establish a GDAP relationship [Granular delegated admin privileges (GDAP) introduction - Partner Center | Microsoft Learn](https://learn.microsoft.com/en-us/partner-center/gdap-introduction) with your tenant. This invitation must be accepted by a Global Administrator in the tenant, and will provide the following roles to our support technicians while the relationship is in place.

To implement a GDAP request, select from the following GDAP sets and provide the email and name of the Global Administrator receiving the invite in your request to [support@calltower.com](mailto:support@calltower.com).
