Frequently Asked Questions

What is a GDAP relationship in Microsoft 365?

Granular Delegated Admin Privileges (GDAP) is a security feature that allows organizations to provide external partners or support providers with limited, time-bound access to their Microsoft 365 tenant, ensuring they only have the permissions necessary to perform their specific tasks.

Who can initiate a GDAP request?

The GDAP relationship request must be initiated by the Microsoft partner or support provider (such as IONOS or a managed service provider). The customer then reviews and approves the request from within their Microsoft 365 admin center.

How long does a GDAP relationship last?

GDAP relationships are strictly time-bound. The exact duration is specified during the request process and cannot exceed two years. Once the relationship expires, the partner loses access and a new request must be submitted if continued support is needed.
